     This application is a divisional application of U.S. Ser. No. 14/667,685, filed on Mar. 25, 2015, which claims priority under 35 U.S.C. § 119 from Japanese Patent Applications No. 2014-072917 filed Mar. 31, 2014 and No. 2014-160537 filed Aug. 6, 2014. The entire disclosures of all of these applications are incorporated by reference herein. 
    
    
     BACKGROUND 
     Field of the Invention 
     The present invention relates to a pump device and a terminal member, and in particular relates to a pump device including a noise suppression device, a terminal member, and a pump device including a noise suppression device using the terminal member. 
     Related Art 
     There are pump devices that include an electrical noise suppression device (noise suppression device) for suppressing noise from being generated during motor driving (see, for example, Japanese Patent Application Laid-Open (JP-A) No. 2012-44814). Such an electrical noise suppression device is configured including a pair of choke coils and a pair of capacitors. The choke coils and the capacitors are housed in a cylindrical shaped housing. The pair of capacitors is disposed inclined with respect to the axial direction of the housing. This thereby enables the installation space for the capacitors to be made smaller when viewed from along the axial direction of the housing. 
     However, in such pump device, due to the pair of capacitors being disposed inclined with respect to the axial direction of the housing as described above, the results in the installation space for the capacitors becoming relatively larger in the axial direction of the housing. There is thus room for improvement in such pump device from the viewpoint of efficient disposition of capacitors in electrical noise suppression device. 
     There is a tendency recently to even further reduce the installation space for an electrical noise suppression device under demand for more compact pump device. Electrical elements configuring the electrical noise suppression device, such as capacitors, are accordingly disposed closer to each other. Moreover, in an electrical noise suppression device, a configuration can be adopted, for example, with a terminal member as a common earth contact by connecting earth terminals of plural electrical elements to the terminal member connected to ground. In such a case, plural press-fit grooves are formed to the terminal member, into which the earth terminals are press-fit connected. 
     However, if electrical elements are disposed closer to each other, in the terminal member, there is concern about being able to achieve a good press-fit of earth terminals due to adjacent press-fit grooves being disposed in the vicinity of each other. Namely, when press-fitting earth terminals into press-fit grooves, the terminal member displaces (deforms) such that the press-fit groove spreads out to the outsides in the groove width direction. In other words, the terminal member would displace (deform) such that this press-fit groove spreads toward the adjacent press-fit groove side. As a result, the groove width of the adjacent press-fit groove would get smaller, making it difficult to press-fit connect the terminal of an electrical element to the adjacent press-fit groove. 
     SUMMARY 
     In consideration of the above circumstances, a pump device capable of disposing a first electrical element and a second electrical element in a noise suppression device with good efficiency is provided, and a terminal member capable of achieving good connection for plural terminals is provided, and a pump device provided with a noise suppression device using such a terminal member is provided. 
     A pump device of an aspect includes: a housing formed in a tubular shape, that includes: a motor housing section that houses a motor, and a pump chamber that houses an impeller which is axially supported at a rotation shaft of the motor so as to be capable of rotating integrally with the rotation shaft; a cap that includes a power supply terminal for connecting to an external connector and that closes an opening of the motor housing section; a noise suppression device that is provided between the cap and the motor, that is connected between the power supply terminal and the motor, and that suppresses noise from being generated during driving of the motor; a first electrical element that configures the noise suppression device, that is disposed such that a height direction of the first electrical element is oriented along an orthogonal direction orthogonal to an axial direction of the housing, and that includes a pair of first terminals that extend from one end portion of a first element body of the first electrical element toward one side in the orthogonal direction; and a second electrical element that configures the noise suppression device, that is disposed such that a height direction of the second electrical element is oriented along the orthogonal direction, and that includes a pair of second terminals that extend from one end portion of a second element body of the second electrical element toward another side in the orthogonal direction, wherein one of the second terminals is disposed between the pair of first terminals as viewed along the axial direction of the housing. 
     According to thus configured pump device, the housing formed in the tubular shape includes the motor housing section and the pump chamber. The motor is housed in the motor housing section, and the opening of the motor housing section is closed off with the cap. The impeller is housed in the pump chamber, and is axially supported so as to be capable of rotating as one with the rotation shaft of the motor. Moreover, the noise suppression device is provided between the cap and the motor, and is configured including the first electrical element and the second electrical element. The noise suppression device is electrically connected between the power supply terminal provided at the cap and the motor, such that noise is suppressed from being generated during driving of the motor by the noise suppression device. 
     The first electrical element and the second electrical element are disposed with their height directions oriented along the orthogonal direction which is orthogonal to the axial direction of the housing. Namely, the first electrical element and the second electrical element are disposed in a state of lying down so as to be orthogonal to the axial direction of the housing. This thereby enables the installation space for the first electrical element and the second electrical element to be suppressed from becoming too large in the axial direction of the housing. 
     The pair of first terminals of the first electrical element extend from the one end portion of the element body of the first electrical element toward the one side in the orthogonal direction, and the pair of second terminals of the second electrical element extend from the one end portion of the element body of the second electrical element toward the another side in the orthogonal direction. As viewed along the housing axial direction, one of the second terminals is disposed between the pair of first terminals. In other words, the first terminals and the second terminals are disposed alternately to each other as viewed along the housing axial direction. As a result, the installment space (the arranged surface area) of the first electrical element and the second electrical element as viewed along the housing axial direction can be made smaller than a case in which the first electrical element and the second electrical element are disposed in a row adjacent to each other. Thus in the pump device of the aspect, the first electrical element and the second electrical element can be efficiently disposed (arranged) due to efficient utilization of the space between the pair of first terminals (second terminals) to dispose the second terminal (the first terminal). 
     In the pump device of another aspect, in addition to the above configuration, the noise suppression device includes a retaining member that retains the first electrical element and the second electrical element, the retaining member including: a base portion on which the first electrical element and the second electrical element are mounted, and a pair of stopper portions that abut the one end portion of the first element body of the first electrical element and the one end portion of the second element body of the second electrical element, respectively. 
     According the pump device configured as described above, the noise suppression device includes the retaining member, and the first electrical element and the second electrical element are mounted to the base of the retaining member, and are retained by the retaining member. 
     Moreover, the retaining member includes the pair of stopper portions. The pair of stopper portions respectively abuts portions at the one ends of the element bodies of the first electrical element and the second electrical element. 
     Thus the position in the orthogonal direction of the first electrical element (the second electrical element) with respect to the retaining member can be set with reference to the one end portion of the element body. This thereby enables, for example, variation to be suppressed in positioning between the terminal member to which the first terminal (second terminal) of the first electrical element (the second electrical element) is connected, and the first terminal (second terminal), enabling stable connection of the first terminal (second terminal) to the terminal member. 
     In the pump device of another aspect, in addition to the above configuration, the retaining member further includes a pair of biasing portions that are resiliently deformable in the orthogonal direction, that abut another end portion of the first element body of the first electrical element and another end portion of the second element body of the second electrical element, respectively, and that bias the first element body of the first electrical element and the second element body of the second electrical element toward respective sides of the stopper portions. 
     The retaining member further includes the pair of biasing portions. The biasing portions are configured so as to be resiliently deformable in the orthogonal direction, respectively abut portions at the another ends of the element bodies of the first electrical element and the second electrical element, and bias the element bodies toward the corresponding stopper portion side. 
     Accordingly, this also enables the position of the first electrical element (second electrical element) in the orthogonal direction with respect to the retaining member to be set with reference to the one end portion of the element body. Accordingly, for example, variation in positioning is suppressed between the terminal member to which the first terminal (second terminal) of the first electrical element (second electrical element) is connected and the first terminal (second terminal), enabling stable connection to be made of the first terminal (second terminal) with the terminal member. 
     In the pump device of another aspect, in addition to the above configuration, the biasing portions include sloping faces that abut the another end portion of the first element body of the first electrical element and the another end portion of the second element body of the second electrical element, respectively; and the sloping faces are sloped, with respect to the axial direction of the housing, toward respective sides of the first element body of the first electrical element and the second element body of the second electrical element, and toward a base portion. 
     According to the thus configured pump device, the biasing portions include the sloping faces, and the sloping faces abut the another end portions of the element bodies of the first electrical element and second electrical element, respectively. The sloping faces are sloped, with respect to the axial direction of the housing, toward the respective element body sides and the base portion side. Thus biasing forces from the biasing portions can be made to act on the element bodies of the first electrical element and the second electrical element toward the base portion side. This thereby enables the retention performance to be improved of the retaining member with respect to the first electrical element and the second electrical element. 
     In the pump device of another aspect, in addition to the above configuration, the retaining member is formed from resin, and the base portion and the biasing portions are integrally formed. 
     According to the pump device configured as described above, the retaining member that retains the first electrical element and the second electrical element can be simply configured due to the retaining member being made from resin, and the base portion and the biasing portions being integrally formed. 
     In the pump device of another aspect, in addition to the above configuration, the first electrical element and the second electrical element are respectively a first capacitor and a second capacitor. 
     In the pump device of another aspect, in addition to the above configuration, the noise suppression device includes a pair of choke coils and a third electrical element (third capacitor) in addition to the first electrical element (first capacitor) and the second electrical element (second capacitor); the choke coils are disposed between the first electrical element and the second electrical element in a circumferential direction of the housing; and the third electrical element is disposed between the pair of choke coils as viewed along the axial direction of the housing, and the third electrical element is disposed so as to overlap with the first electrical element and the second electrical element in the axial direction of the housing. 
     According to the pump device configured as described above, the noise suppression device includes the pair of choke coils and the third electrical element in addition to the first electrical element and the second electrical element. The choke coils are disposed, in the circumferential direction of the housing, between the first electrical element and the second electrical element. This thereby enables efficient arrangement of the first electrical element, the second electrical element, and the pair of choke coils in the noise suppression device. 
     Moreover, the third electrical element is disposed between the pair of choke coils as viewed along the axial direction of the housing, and the third electrical element is disposed so as to overlap with the first electrical element and the second electrical element in the housing axial direction. This thereby enables the third electrical element to be mounted to the noise suppression device, while suppressing the noise suppression device from becoming larger in the radial direction of the housing. 
     A terminal member of an aspect includes: a plurality of connection tabs that are configured from a metal plate member, the connection tabs being disposed adjacently in a plate thickness direction thereof; a coupling portion that couples the connection tabs; press-fit grooves that are formed at the respective connection tabs such that the press-fit grooves are disposed so as to be displaced from each other in width direction of the connection tabs, terminals of electrical elements being press-fitted into the press-fit grooves respectively; and insertion grooves that are respectively formed at the connection tabs, the insertion grooves being disposed adjacent to the press-fit grooves in the width direction of the connection tabs, and a terminal of the electrical element that is press-fitted into the press-fit groove of another connection tab being inserted in the insertion groove. 
     More specifically, the terminal member of the aspect includes: a plurality of connection tabs that are configured from a metal plate member, the connection tabs being disposed adjacently in a plate thickness direction thereof; a coupling portion that couples the connection tabs; first and second press-fit grooves that are formed at the respective connection tabs such that the first and the second press-fit grooves are disposed so as to be displaced from each other in a width direction of the connection tabs, terminals of electrical elements being press-fitted into the first and the second press-fit grooves respectively; and first and second insertion grooves that are formed at the respective connection tabs such that the first and the second insertion grooves are disposed so as to be displaced from each other in the width direction, wherein at one of the connection tabs, the first insertion groove is disposed adjacent to the second press-fit groove in the width direction, at another one of the connection tabs, the second insertion groove is disposed adjacent to the first press-fit groove in the width direction, one of the terminals of the electrical elements, which is press-fitted into the first press-fit groove, is inserted in the first insertion groove, and another one the terminals of the electrical elements, which is press-fitted into the second press-fit groove, is inserted in the second insertion groove. 
     In the terminal member of the above configuration, the plural connection tabs configured from the metal plate member are coupled by the coupling portion and disposed in a row in the plate thickness direction. The press-fit groove for press-fitting the terminal of the electrical element is formed to each of the connection tabs, and the press-fit grooves are disposed so as to be displaced from each other in the width direction of the connection tabs. Moreover, an insertion groove is formed to each of the connection tabs, and the insertion groove is disposed adjacent to the press-fit groove in the width direction of the connection tab. The terminal of the electrical element that has been press-fitted into the press-fit groove of another connection tab is inserted into the insertion groove. 
     Therefore, in each of the connection tabs, displacement (deformation) of the connection tab arising when the terminal is press-fitted into the press-fit groove can be absorbed in the insertion groove, helping or enabling to prevent change in the groove width dimension of another press-fit groove due to such displacement (deformation). Accordingly, good connection of plural terminals to the terminal member can be achieved. 
     In the terminal member of another aspect, in addition to the above configuration, the terminals of the electrical elements press-fitted into the (first and second) press-fit grooves are earth terminals. 
     According to the thus configured terminal member, the terminal member can be configured as a common earth terminal member for plural electrical elements. 
     In the terminal member of another aspect, in addition to the above configuration, the coupling portion is disposed at outer sides in the width direction with respect to the (first and second) press-fit grooves and the (first and second) insertion grooves. 
     According to the thus configured terminal member, due to the coupling portion being disposed at the width direction outsides of the connection tabs with respect to the press-fit grooves and the insertion grooves, further helping or enabling to prevent change in the groove width dimension of another press-fit groove when a terminal is press-fitted into the press-fit groove. 
     In the terminal member of another aspect, in addition to the above configuration, the coupling portion is a bent portion at which the metal plate member is bent. 
     According to the thus configured terminal member, due to the coupling portion being configured by the bent portion, the plural connection tabs can be formed at the connection portion by bending processing of a single plate member. This thereby enables easier configuration of the terminal member than, for example, a case in which the connection tabs are coupled such as by welding, enabling an increase in cost of the terminal member to be suppressed. 
     In the terminal member of another aspect, in addition to the above configuration, in an expanded state of the connection tabs, which is a state of the metal plate member not being bent, the (first and second) press-fit groove and the (first and second) insertion groove are disposed at positions that are symmetrical about a bend line of the bent portion. 
     According to the thus configured terminal member, due to the press-fit grooves and the insertion grooves being disposed in the expanded state of the connection tabs at positions that are symmetrical to each other about the bend line of the bent portion, a configuration can be achieved in which the press-fit grooves and the insertion grooves are easily corresponded to (aligned with) each other. 
     In the terminal member of another aspect, in addition to the above configuration: a first taper portion is formed at an opening portion of the first (second) press-fit groove so as to open out toward an outer side in a groove width direction of the first (second) press-fit groove on progression toward an opening side of the first (second) press-fit groove; a second taper portion is formed at an opening portion of the first (second) insertion groove so as to open out toward an outer side in a groove width direction of the first (second) insertion groove on progression toward an opening side of the first (second) insertion groove; and in the expanded state of the connection tabs, the first taper portion and the second taper portion are disposed at positions symmetrical to each other about the bend line of the bent portion. 
     According to the thus configured terminal member, due to the first taper portion and the second taper portion being disposed at positions symmetrical to each other about the bend line of the bent portion in the expanded state of the connection tabs, a configuration can be achieved in which the first taper portion and the second taper portion are easily corresponded to (aligned with) each other. 
     In the terminal member of another aspect, in addition to the above configuration, a width dimension of the one of the terminals of the electrical elements is larger than a groove width dimension of the first press-fit groove, and smaller than a groove width dimension of the first insertion groove, and a width dimension of the another one of the terminals of the electrical elements is larger than a groove width dimension of the second press-fit groove, and smaller than a groove width dimension of the second insertion groove. 
     A pump device of another aspect includes: a housing formed in a tubular shape, that includes: a motor housing section that houses a motor, and a pump chamber that houses an impeller which is axially supported at a rotation shaft of the motor so as to be capable of rotating integrally with the rotation shaft; a cap that includes a power supply terminal for connecting to an external connector and that closes an opening of the motor housing section; and a noise suppression device that includes a terminal member of any one of the above aspects, wherein the noise suppression device is provided between the cap and the motor, is connected between the power supply terminal and the motor, and suppresses noise from being generated during driving of the motor. 
     According to the thus configured pump device, in the terminal member, a good connection can be achieved of plural terminals due to the noise suppression device being configured including the terminal member configured as described above.

     DETAILED DESCRIPTION 
     Explanation follows regarding a vehicle washer pump device  10  serving as a “pump device” (referred to below as washer pump  10 ) according to a first exemplary embodiment, with reference to the drawings. The washer pump  10  is configured as a centrifugal pump. The washer pump  10  is assembled to a washer tank (not shown in the drawings) installed inside an engine room (a power unit chamber) of a vehicle (an automobile), in a state in which the up-down direction of the washer pump  10  (the arrow A direction and the arrow B direction in  FIG. 6 ) coincides with (is aligned with) the up-down direction of the vehicle. As illustrated in  FIG. 6 , the washer pump  10  is configured including a pump body  12 , a connector cap  40 , and a noise suppression device  50 . Explanation follows regarding each configuration. 
     Pump Body  12   
     As illustrated in  FIG. 7 , the pump body  12  is configured including a housing  14 , a motor  30 , and an impeller  38 . The housing  14  is made from resin and formed in a substantially circular cylindrical shape with an axial direction thereof along the up-down direction. The housing  14  is configured including a motor housing section  16 , an inlet  20 , a pump chamber  22 , and an outlet  28 . 
     The motor housing section  16  configures the upper side portion of the housing  14  (the arrow A direction side section of  FIG. 7 ), and is formed in a bottomed, substantially circular cylindrical shape, open toward the upper side. The bottom wall portion of the motor housing section  16  configures a partition wall  18 , and the inside of the inlet  20 , as described below, and the inside of the motor housing section  16  are partitioned by the partition wall  18 . The motor  30  is housed coaxially inside the motor housing section  16 , and a rotation shaft  32  of the motor  30  pierces through the partition wall  18 , and projects out from the partition wall  18  to the lower side. A sealing member is disposed in a shaft hole portion of the partition wall  18 , through which the rotation shaft  32  passes, so as to prevent penetration of washer liquid (liquid) into the motor housing section  16 . A pair of motor terminals  34  and  36  (see  FIG. 6 ) are provided at outer circumferential portions on the upper end portion of the motor  30 . The motor terminals  34  and  36  are disposed at positions with point symmetry to each other about the axial line of the motor  30 , and are formed in substantially rectangular plate shapes that project out to the upper side from the upper end portion of the motor  30  (along the direction of assembly of the connector cap  40  to the housing  14 , as described below). 
     The inlet  20  is disposed at the lower side of the motor housing section  16 . The inlet  20  is formed in a substantially circular cylindrical shape, with its axial direction in a direction orthogonal to the axial line AL 1  of the housing  14 , so as to extend (project) out to the radial direction outside of the housing  14 . The internal space of the inlet  20  configures an intake hole  20 A, with the intake hole  20 A extending as far as the lower side of the motor housing section  16 . The housing  14  is assembled to an assembly hole of the washer tank through a grommet (not shown in the drawings) or the like, in a state in which the inlet  20  is inserted into the washer tank. 
     The pump chamber  22  is disposed at a lower end portion of the housing  14 , further to the lower side than the inlet  20 . The pump chamber  22  is formed with a substantially circular shaped cross-section, open toward the lower side. An end cap  24  made from resin is fixed in a watertight state to the open portion at the lower end portion of the housing  14  by ultrasonic welding or the like. The pump chamber  22  is thereby closed off by the end cap  24 . A communication hole  26  is formed between the pump chamber  22  and the intake hole  20 A of the inlet  20 . The communication hole  26  is disposed coaxially to the rotation shaft  32  of the motor  30 , and communicates the inside of the pump chamber  22  with the inside of the inlet  20  (the intake hole  20 A) at a central portion of the pump chamber  22 . The rotation shaft  32  of the motor  30  extends through the inside of the inlet  20  and the communication hole  26 , through to the pump chamber  22 , with the leading end portion of the rotation shaft  32  disposed inside the pump chamber  22 . 
     The impeller  38  is housed inside the pump chamber  22 , with the impeller  38  axially supported at the leading end portion of the rotation shaft  32  of the motor  30  so as to be capable of rotating integrally with the rotation shaft  32  of the motor  30 . The impeller  38  includes plural vanes, with the vanes extending to the radial direction outside of the rotation shaft  32 . 
     The outlet  28  is formed in a substantially circular cylindrical shape, and extends (projects) from the lower end portion of the housing  14  toward the radial direction outside of the housing  14 . More specifically, the outlet  28  projects from the housing  14  toward the opposite side to the side toward which the inlet  20  projects, and is disposed on the axial line AL 2  direction of the inlet  20  in plan view. The inside of the outlet  28  is in communication with the inside of the pump chamber  22 . The washer liquid in the washer tank is fed under pressure to the outlet  28  when the impeller  38  is rotated to one side in the rotation directions. 
     The outlet  28  is connected through a hose (not shown in the drawings) to a front nozzle for washing a front windshield (glass) of the vehicle. Configuration is thus made such that when the impeller  38  rotates, the washer liquid in the pump chamber  22  is discharged (jetted) from the outlet  28 , so as to be supplied to the front nozzle. 
     Connector Cap  40   
     As illustrated in  FIG. 6 , the connector cap  40  is formed in a bottomed, substantially circular cylindrical shape, open toward the lower side, and is disposed coaxially to the housing  14  at the upper side of the housing  14 . The lower end portion of the connector cap  40  is fitted into the opening portion of the motor housing section  16  in the housing  14 , and the connector cap  40  is fixed in a watertight state to the housing  14  by ultrasonic welding or the like. The open portion of the motor housing section  16  is thereby closed off by the connector cap  40 . 
     As illustrated in  FIG. 8A , a pair of fixing tabs  42  are integrally formed to the connector cap  40 , for fixing the noise suppression device  50 , as described below. The fixing tabs  42  extend from an upper wall of the connector cap  40  toward the lower side, and fixing hooks  42 A are formed to the leading end portions of the fixing tabs  42 . 
     As illustrated in  FIG. 6 , a connector section  40 A is integrally formed to the connector cap  40 . The connector section  40 A is formed in a substantially rectangular tubular shape projecting from the upper wall of the connector cap  40  to the upper side. More specifically, the connector section  40 A slopes toward the opposite side to the side toward which the inlet  20  projects on progression toward the upper side as viewed from the side. 
     A pair of power supply terminals  44  and  46  are integrally provided to the connector cap  40 . The power supply terminals  44  and  46  are configured by conductive metal plate members, and are formed in substantially rectangular (longitudinal) shapes. Portions at one end of the power supply terminal  44  and  46  are disposed inside the connector section  40 A. The power supply terminals  44  and  46  are each bent into a specific shape, with portions at another end of the power supply terminals  44  and  46  projecting out from the upper wall of the connector cap  40  toward the lower side. The another end portions of the power supply terminals  44  and  46  are connected to the motor terminals  34  and  36  of the motor  30  through the noise suppression device  50 , as described below. Configuration is thereby adopted such that current is supplied to the motor  30  by connecting external connectors (not shown in the drawings) of a harness on the vehicle side to the connector section  40 A. 
     Noise Suppression Device  50   
     As illustrated in  FIG. 6 , the noise suppression device  50  is disposed between the motor  30  and the connector cap  40 , in a configuration such that electrical connection is made between the motor terminals  34  and  36  of the motor  30  and the power supply terminals  44  and  46  of the connector section  40 A. Thus noise generated while driving the motor  30  is suppressed by the noise suppression device  50 . 
     As illustrated in  FIG. 2 , the noise suppression device  50  includes three capacitors that absorb noise arising during driving of the motor  30  (a first capacitor  70 , a second capacitor  80 , and a third capacitor  90  that are each radial lead type capacitors, and are each corresponds to “electrical element” in the aspects), and a pair of choke coils (a first choke coil  100  and a second choke coil  102 ). The noise suppression device  50  also includes a pair of power supply side relay and  112 , a pair of motor side relay terminal members  114  and  116  (elements that are broadly defined as “relay terminals”), and an earth terminal member (a ground terminal member)  118  (elements that is broadly defined as a “relay terminal”). These components configuring the noise suppression device  50  are retained by a holder  52  serving as a “retaining member”. Explanation first follows regarding the electrical connection relationship between the components configuring the noise suppression device  50 , and then regarding each of the components. 
     As illustrated in  FIG. 3 , in the noise suppression device  50 , one end of the first choke coil  100  is connected to the power supply terminal  44  by the power supply side relay terminal member  110 , and one end of the second choke coil  102  is connected to the power supply terminal  46  by the power supply side relay terminal member  112 . 
     Another end of the first choke coil  100  is connected to the motor terminal  34  of the motor  30  and to one end of the first capacitor  70  by the motor side relay terminal member  114 . Another end of the second choke coil  102  is connected to the motor terminal  36  of the motor  30  and to one end of the second capacitor  80  by the motor side relay terminal member  116 . The first choke coil  100  and the second choke coil  102  are thereby connected in series to the positive electrode side and the negative electrode side of the motor  30 , respectively. Another end of the first capacitor  70  and another end of the second capacitor  80  are connected to ground by the earth terminal member  118 . The third capacitor  90  is connected to the power supply side relay terminal members  110  and  112  so as to be connected in parallel to the motor  30 . 
     As illustrated in  FIG. 1 , the holder  52  is made from resin. The holder  52  includes a substantially circular plate shaped base portion  54 . The base portion  54  is disposed with its plate thickness direction along the up-down direction, and is disposed coaxially to the housing  14  and the connector cap  40 . 
     In the following explanation, for ease of explanation, in plan view, a line rotated by 45 degrees in the clockwise direction from the axial line AL 2  of the inlet  20  about the axial line of the base portion  54  (namely the axial line AL 1  of the housing  14 ) is referred to as a first reference line L 1 , and a line passing through the axial line AL 1  of the base portion  54  and orthogonal to the first reference line L 1  is referred to as a second reference line L 2 . The direction along the first reference line L 1  is referred to as a first direction, one side in the first direction (one side in orthogonal direction in the aspects) refers to the arrow C direction side, and another side in the first direction (another side in the orthogonal direction in the aspects) refers to the arrow D direction side. The direction along the second reference line L 2  is referred to as a second direction, one side in the second direction refers to the arrow E direction side, and another side in the second direction refers to the arrow F direction side. 
     A pair of notches  56 A and  56 B are formed to outer circumferential portions of the base portion  54 . The notches  56 A and  56 B are disposed at positions with point symmetry to each other about the axial line AL 1 , as reference, of the base portion  54 . The notch  56 A is disposed so as to be adjacent with respect to the second reference line L 2  at the first direction one side, and the notch  56 B is disposed so as to be adjacent with respect to the second reference line L 2  at the first direction another side. The notches  56 A and  56 B are formed with substantially V-shaped profiles, open toward the radial direction outside of the base portion  54 . The fixing hooks  42 A of the fixing tabs  42  of the connector cap  40  anchor onto the edge portions of the notches  56 A and  56 B. Thereby not only are the power supply side relay terminal members  110  and  112  being connected to the power supply terminals  44  and  46 , but the holder  52  is also fixed to the connector cap  40  (see  FIG. 8B ), and the noise suppression device  50  is housed inside the connector cap  40 . 
     The first capacitor  70  is mounted to the upper face of the base portion  54 . The first capacitor  70  includes a first element body  72  serving as an “element body” formed with a substantially rectangular cuboid shape, and the first element body  72  is disposed with its height direction along the first direction. Namely, the first capacitor  70  is disposed in a lying down state, lying in the direction orthogonal to the axial direction of the housing  14 . The first element body  72  is disposed with its thickness direction in the up-down direction, and with its width direction along the second direction, at the first direction another side with respect to the second reference line L 2 . The width direction center of the first element body  72  is disposed so as to be displaced to the one side in the second direction with respect to the first reference line L 1 , and with a portion of the first element body  72  overlapping with the first reference line L 1  in plan view. 
     A pair of bulging portions  74  are formed to both width direction side portions of one end portion  72 A of the first element body  72 . The bulging portions  74  bulge out from the first element body  72  to the first direction one side. The first capacitor  70  also has a pair of first terminals  76 A and  76 B. The first terminals  76 A and  76 B extend out from the bulging portions  74  to the first direction one side. The first terminal  76 A is disposed at the second direction another side with respect to the first reference line L 1 , and the first terminal  76 B is disposed at the second direction one side with respect to the first reference line L 1 . The leading end portions of the first terminals  76 A and  76 B are disposed at the first direction one side with respect to the second reference line L 2 . 
     The second capacitor  80  is formed with the same structure as that of the first capacitor  70 , and is mounted to the upper face of the base portion  54 . Namely, the second capacitor  80  includes a second element body  82  serving as an “element body”, a pair of bulging portions  84  which are formed to one end portion  82 A of the second element body  82 ; and a pair of second terminals  86 A and  86 B that respectively extend out from the bulging portions  84 . A portion at another end of the second element body  82  configures an another end portion  82 B. The first capacitor  70  and the second capacitor  80  are disposed so as to have point symmetry to each other about the axial line AL 1 , as reference, of the base portion  54  in plan view. Namely, the second terminal  86 A is disposed between the pair of first terminals  76 A and  76 B of the first capacitor  70 , with the first terminals  76 A and  76 B and the second terminals  86 A and  86 B disposed alternately to each other along the second direction. The first capacitor  70  and the second capacitor  80  thereby overlap with each other in the first direction and the second direction in plan view. 
     A pair of stopper portions  58  is formed to the upper face of the base portion  54  as described above, to restrict the positions in the first direction of the first capacitor  70  and the second capacitor  80  with respect to the base portion  54 . The stopper portions  58  are respectively disposed between the pair of bulging portions  74  of the first capacitor  70  and between the pair of bulging portions  84  of the second capacitor  80 , and respectively abut the one end portion  72 A of the first element body  72  and the one end portion  82 A of the second element body  82 . Movement of the first capacitor  70  to the first direction one side and movement of the first capacitor  70  in the second direction are thereby restricted by the stopper portion  58  abutting the first element body  72 . Similarly, movement of the second capacitor  80  to the first direction another side and movement of the second capacitor  80  in the second direction are restricted by the stopper portion  58  abutting the second element body  82 . 
     A pair of engaging tabs  60  are also integrally formed as “biasing portions” at outer circumferential portions of the upper face of the base portion  54 . The engaging tabs  60  are formed so as to correspond to the first element body  72  and the second element body  82 , respectively, and the pair of engaging tabs  60  is configured so as to have point symmetry to each other about the axial line AL 1  of the base portion  54 . Thus in the following explanation, explanation will be given regarding the engaging tab  60  corresponding to the first element body  72 , and explanation will be omitted regarding the engaging tab  60  corresponding to the second element body  82 . 
     As illustrated in  FIG. 4 , the engaging tab  60  is disposed on the opposite side of the first element body  72  to that of the stopper portion  58 . The engaging tab  60  is formed in a substantially number-7 plate shape, is disposed with the plate thickness direction thereof along the first direction, and extends from the base portion  54  to the upper side. More specifically, the engaging tab  60  is configured including a first arm  60 A extending to the upper side from the base portion  54 , a second arm  60 B extending from the upper end portion of the first arm  60 A toward the second direction one side, and a third arm  60 C extending from the leading end portion (one end portion in the second direction) of the second arm  60 B toward the lower side. The engaging tab  60  is configured so as to be resiliently deformable in the first direction. 
     An engagement hook  62  is formed to a lower end portion of the third arm  60 C. The engagement hook  62  projects out from the third arm  60 C to the first direction one side (the first element body  72  side). The engagement hook  62  includes a sloping face  62 A, and the sloping face  62 A slopes toward the first direction another side (the side in the direction away from the first element body  72 ) on progression toward the lower side as viewed along the second direction. In other words, the sloping face  62 A slopes, with respect to the up-down direction, toward the base portion  54  side and toward the first element body  72  side. The sloping face  62 A abuts an another end portion  72 B of the first element body  72 , and the engaging tab  60  is resiliently deformed to the first direction another side. The first element body  72  is thereby in a state biased to the first direction one side (the stopper portion  58  side) and to the lower side by the engaging tab  60 , retaining the first capacitor  70  onto the base portion  54 . 
     As illustrated in  FIG. 2 , the earth terminal member  118  is configured from a conductive metal plate member, and retained by the base portion  54 . The earth terminal member  118  extends in the substantially up-down direction, and a connecting portion  118 A is formed to a leading end portion of the earth terminal member  118 . As illustrated in  FIG. 1 , the connecting portion  118 A is disposed at the upper side of a central portion of the base portion  54 , with its plate thickness direction along the first direction, and is disposed on the second reference line L 2  in plan view. A pair of slits  118 B is formed to the connecting portion  118 A, and the first terminal  76 A of the first capacitor  70  and the second terminal  86 A of the second capacitor  80  are press-fit connected inside the pair of slits  118 B respectively. The lower end portion of the earth terminal member  118  is connected to ground. 
     As illustrated in  FIG. 2 , the motor side relay terminal member  114  is configured by a conductive metal plate member, and retained by the base portion  54 . The motor side relay terminal member  114  includes a connection portion  114 A. As illustrated in  FIG. 1 , the connection portion  114 A is disposed, with its plate thickness direction along the first direction, at a position on the second direction one side with respect to the connecting portion  118 A of the earth terminal member  118 , and is disposed on the second reference line L 2  in plan view. A slit  114 B is formed to the connection portion  114 A, and the first terminal  76 B of the first capacitor  70  is press-fitted connected into the slit  114 B. The motor side relay terminal member  114  and the first capacitor  70  are thereby electrically connected together. 
     Moreover, as illustrated in  FIG. 2 , the motor side relay terminal member  114  includes a connection portion  114 C. The connection portion  114 C is disposed at the radial direction outside of the base portion  54 , and is bent and curved into a substantially letter B shape in plan view. The motor terminal  34  of the motor  30  is press-fitted connected (plug connected) inside the connection portion  114 C. The motor  30  and the motor side relay terminal member  114  are thereby electrically connected together. 
     The motor side relay terminal member  114  also includes a connection portion  114 D. The connection portion  114 D is bent into a substantially V-shaped cross-section, open toward the upper side. The connection portion  114 D is caulked (crimped) so as to wrap around (so as to grip or hold) the terminal of the first choke coil  100  as described below (see  FIG. 1  and  FIG. 5 ). 
     As illustrated in  FIG. 2 , the motor side relay terminal member  116  is configured by a conductive metal plate member, and is retained by the base portion  54 . The motor side relay terminal member  114  and the motor side relay terminal member  116  are configured so as to have point symmetry to each other about the axial line AL 1 , as reference, of the base portion  54 . Namely, as illustrated in  FIG. 1 , the motor side relay terminal member  116  includes a connecting portion  116 A. The connecting portion  116 A is disposed at a position on the second direction another side with respect to the connecting portion  118 A of the earth terminal member  118 , is disposed with its plate thickness direction along the first direction, and is disposed on the second reference line L 2  in plan view. A slit  116 B is formed to the connecting portion  116 A, and the second terminal  86 B of the second capacitor  80  is press-fit connected into the slit  116 B. The motor side relay terminal member  116  and the second capacitor  80  are thereby electrically connected together. 
     As illustrated in  FIG. 2 , the motor side relay terminal member  116  includes a connection portion  116 C, and the motor terminal  36  of the motor  30  is press-fitted connected (plug connected) into the connection portion  116 C. The motor  30  and the motor side relay terminal member  116  are thereby electrically connected together. The motor side relay terminal member  116  also includes a connection portion  116 D. The connection portion  116 D is caulked (crimped) so as to wrap around (so as to grip or hold) the terminal of the second choke coil  102 , as described below (see  FIG. 1  and  FIG. 5 ). 
     As illustrated in  FIG. 1  and  FIG. 2 , the first choke coil  100  is formed in a substantially circular pillar shape, disposed with its axial direction along the up-down direction. The first choke coil  100  is disposed at the first direction one side with respect to the first capacitor  70  and at the second direction one side with respect to the second capacitor  80 , and is retained in the holder  52 . As illustrated in  FIG. 5 , the terminal at a lower end portion of the first choke coil  100  is connected to the connection portion  114 D of the motor side relay terminal member  114 , and the terminal at an upper end portion of the first choke coil  100  is connected to the power supply side relay terminal member  110 , as described below. 
     As illustrated in  FIG. 1  and  FIG. 2 , the second choke coil  102  is formed in a substantially circular pillar shape, and is disposed with its axial direction along the up-down direction. The second choke coil  102  is disposed at a position with point symmetry to the first choke coil  100  about the axial line AL 1 , as reference, of the base portion  54  in plan view, and is retained by the holder  52 . Namely, the second choke coil  102  is disposed at the second direction another side with respect to the first capacitor  70 , and at the first direction another side with respect to the second capacitor  80 . The first capacitor  70 , the first choke coil  100 , the second capacitor  80 , and the second choke coil  102  are thereby disposed in a row in the circumferential direction of the base portion  54 . As illustrated in  FIG. 5 , the terminal at the lower end portion of the second choke coil  102  is connected to the connection portion  116 D of the motor side relay terminal member  116 , and the terminal at the upper end portion of the second choke coil  102  is connected to the power supply side relay terminal member  112 , as described below. 
     As illustrated in  FIG. 2 , the power supply side relay terminal member  110  is configured by a conductive metal plate member, and is retained by the base portion  54 . The power supply side relay terminal member  110  includes a connection portion  110 A, and the connection portion  110 A is bent into a substantially V-shaped cross-section open toward the lower side. The connection portion  110 A is caulked (crimped) so as to wrap around (so as to grip or hold) the terminal at the upper end portion of the first choke coil  100 , as described below (see  FIG. 5 ). 
     The power supply side relay terminal member  110  includes a connection portion  110 B, and the connection portion  110 B is bent and curved into a substantially B shaped profile in plan view. An another end portion of the power supply terminal  44  is press-fit connected (plug connected) into the connection portion  110 B. The power supply terminal  44  is thereby connected to the motor  30  through the power supply side relay terminal member  110 , the first choke coil  100 , and the motor side relay terminal member  114 . 
     The power supply side relay terminal member  110  also includes a connection portion  110 C. As illustrated in  FIG. 5 , the connection portion  110 C is disposed between the first choke coil  100  and the second choke coil  102 , and disposed at the upper side of the first capacitor  70  and the second capacitor  80 . A slit  110 D is formed in the connection portion  110 C, and a third terminal  96 A of the third capacitor  90  is press-fit connected into the slit  110 D, as described below. 
     As illustrated in  FIG. 2 , the power supply side relay terminal member  112  is formed from a conductive metal plate member, and is retained by the base portion  54 . The power supply side relay terminal member  110  and the power supply side relay terminal member  112  are configured so as to have point symmetry to each other about the axial line AL 1 , as reference, of the base portion  54 . Namely, the power supply side relay terminal member  112  includes a connection portion  112 A, and the connection portion  112 A is caulked (crimped) so as to wrap around (so as to grip or hold) the terminal at the upper end portion of the second choke coil  102  (see  FIG. 5 ). 
     The power supply side relay terminal member  112  includes a connection portion  112 B, and the power supply terminal  46  is press-fit connected (plug connected) into the connection portion  112 B. The power supply terminal  46  is thereby electrically connected to the motor  30  through the power supply side relay terminal member  112 , the second choke coil  102 , and the motor side relay terminal member  116 . Moreover, as illustrated in  FIG. 5 , the power supply side relay terminal member  112  includes a connection portion  112 C, and the connection portion  112 C is disposed between the connection portion  110 C and the second choke coil  102 , and disposed at the upper side of the first capacitor  70  and the second capacitor  80 . A slit  112 D is formed in the connection portion  112 C, and a third terminal  96 B of the third capacitor  90  is press-fit connected into the slit  112 D, as described below. 
     As illustrated in  FIG. 5 , the third capacitor  90  is configured with the same structure as that of the first capacitor  70 . Namely, the third capacitor  90  includes a third element body  92  (an element that is broadly defined as an “element body”), a pair of bulging portions  94  that are formed to one end portion  92 A of the third element body  92 , and the pair of the third terminals  96 A and  96 B that extend out from the respective bulging portions  94 . The third capacitor  90  is disposed between the first choke coil  100  and the second choke coil  102 , and is disposed at the upper side of the first capacitor  70  and the second capacitor  80 . More specifically, the third element body  92  is disposed at the upper side of the second element body  82 . The third terminal  96 A of the third capacitor  90  is press-fit connected into the slit  110 D of the connection portion  110 C of the power supply side relay terminal member  110 , and the third terminal  96 B of the third capacitor  90  is press-fit connected inside the slit  112 D of the connection portion  112 C of the power supply side relay terminal member  112 . 
     Explanation next follows regarding the operation and advantageous effects of the present exemplary embodiment. 
     In the washer pump  10  configured as described above, the power supply terminals  44  and  46  provided at the connector cap  40  are connected to the motor terminals  34  and  36  of the motor  30  through the noise suppression device  50 . The noise suppression device  50  is configured including the first capacitor  70  and the second capacitor  80  for absorbing noise arising during driving of the motor  30 . The generation of noise during driving of the motor  30  is accordingly suppressed by the noise suppression device  50 . 
     The first capacitor  70  and the second capacitor  80  are disposed such that their height directions are along the first direction. Namely, the first capacitor  70  and the second capacitor  80  are disposed such that their height directions are along a direction orthogonal to the axial direction of the housing  14 . This thereby enables the installation space for the first capacitor  70  and the second capacitor  80  to be suppressed from becoming too large in the axial direction of the housing  14 . 
     The pair of the first terminals  76 A and  76 B of the first capacitor  70  extend out from the first element body  72  toward the first direction one side, and the pair of second terminals  86 A and  86 B of the second capacitor  80  extend out from the second element body  82  toward the first direction another side. The second terminal  86 A is disposed between the pair of first terminals  76 A and  76 B in plan view, and the first terminal  76 A is disposed between the pair of second terminals  86 A and  86 B in plan view. In other words, the first terminals  76 A and  76 B and the second terminals  86 A and  86 B are disposed alternately along the second direction in plan view. This thereby enables the first capacitor  70  and the second capacitor  80  to be disposed so as to overlap with each other in the first direction and in the second direction in plan view. The installation space (disposed surface area in plan view) of the first capacitor  70  and the second capacitor  80  can accordingly be made smaller than, for example, a case in which the first capacitor  70  and the second capacitor  80  are disposed in a row adjacent to each other, such that the first terminals  76 A and  76 B and the second terminals  86 A and  86 B extend out in the same direction. Thus in the washer pump  10 , the first capacitor  70  and the second capacitor  80  can be efficiently disposed due to the space between the pair of the first terminals  76 A and  76 B (and the second terminals  86 A and  86 B) being efficiently utilized to dispose the second terminal  86 A (and the first terminal  76 A). 
     The pair of stopper portions  58  are formed at the base portion  54  of the holder  52 , and the stopper portions  58  abut the one end portion  72 A of the first capacitor  70  and the one end portion  82 A of the second capacitor  80 , respectively. Moreover, the pair of engaging tabs  60  are formed at the base portion  54 , and the pair of engaging tabs  60  respectively abut the another end portion  72 B of the first element body  72  and the another end portion  82 B of the second element body  82 , and resiliently deform in the first directions. The first element body  72  and the second element body  82  are accordingly biased by the pair of engaging tabs  60  toward the stopper portion  58  sides. 
     This thereby enables the position in the first direction of the first capacitor  70  (of the second capacitor  80 ) with respect to the holder  52  to be set with the one end portion  72 A of the first element body  72  (the one end portion  82 A of the second element body  82 ) acting as a reference. As a result, in the first capacitor  70 , variations in the positioning between the first terminals  76 A and  76 B, and the earth terminal member  118  and the motor side relay terminal member  114 , are suppressed, enabling the first terminals  76 A and  76 B to be stably connected to the earth terminal member  118  and the motor side relay terminal member  114 . In the second capacitor  80 , variations in the positioning between the second terminals  86 A and  86 B, and the earth terminal member  118  and the motor side relay terminal member  116 , are also suppressed, enabling the second terminals  86 A and  86 B to be stably connected to the earth terminal member  118  and the motor side relay terminal member  116 . 
     Explanation follows regarding this point, using the first capacitor  70 . In the first capacitor  70 , generally, the length dimension LA of the first terminals  76 A and  76 B (see  FIG. 4 ) is prescribed (defined) by the length from the first element body  72 . There is some variation (tolerance) in the length dimension LA. Thus, in a case in which the stopper portion  58  is omitted from (is not provided at) the base portion  54 , variation would occur in the position of the first element body  72  with respect to the base portion  54  in the first direction, and variation would occur in the length dimension LA of the first terminals  76 A and  76 B. There is accordingly the possibility that the projection amounts of the leading end portions of the first terminals  76 B and  76 A, from the connection portion  114 A of the motor side relay terminal member  114  and from the connecting portion  118 A of the earth terminal member  118 , become smaller. As a result, press-fit allowance (margin) LB (see  FIG. 4 ) at the leading end portions of the first terminals  76 A and  76 B when the first terminals  76 A and  76 B are being press-fit connected to the connection portion  114 A and the connecting portion  118 A become smaller, with the concern arising that a good press-fit of the first terminals  76 A and  76 B into the connection portion  114 A and the connecting portion  118 A might no longer be achieved. 
     In contrast thereto, in the present exemplary embodiment as described above, the position in the first direction of the first capacitor  70  with respect to the holder  52  is set with reference to the one end portion  72 A of the first element body  72 . For the press-fit allowance LB at the leading end portions of the first terminals  76 A and  76 B, there is accordingly no need to consider variation in the positioning of the first element body  72  with respect to the base portion  54  in the first direction. This thereby enables the projection amounts of the leading end portions of the first terminals  76 A and  76 B from the connection portion  114 A of the motor side relay terminal member  114  and from the connecting portion  118 A of the earth terminal member  118  to be secured (insured). As a result, the press-fit allowance LB of the first terminals  76 A and  76 B is secured (insured) when the first terminals  76 A and  76 B are press-fit connected to the connection portion  118 A and the connecting portion  114 A, enabling a good press-fit to be achieved of the first terminals  76 A and  76 B into the connection portion  114 A and the connecting portion  118 A. 
     The another end portion  72 B of the first element body  72  (the another end portion  82 B of the second element body  82 ) abuts the sloping face  62 A of the engagement hook  62  on the engaging tab  60 . The sloping face  62 A slopes (inclines), with respect to the up-down direction, toward both the first element body  72  side (the second element body  82  side) and the base portion  54  side. Due thereto, it is possible that, as a component force, a bias force toward the lower side (toward the base portion  54 ) also acts from the sloping face  62 A to the first element body  72  (the second element body  82 ). This thereby enables improved retaining performance to be achieved of the holder  52  with respect to the first capacitor  70  (the second capacitor  80 ). 
     The holder  52  is configured from resin, with the base portion  54  and the pair of engaging tabs  60  being integrally formed thereto. This thereby enables the holder  52  that retains the first capacitor  70  and the second capacitor  80  to have a simple structure. 
     Moreover, in addition to the first capacitor  70  and the second capacitor  80 , the noise suppression device  50  also includes the first choke coil  100 , the second choke coil  102 , and the third capacitor  90 . The first capacitor  70 , the first choke coil  100 , the second capacitor  80 , and the second choke coil  102  are disposed along the circumferential direction of the base portion  54  (the housing  14 ). This thereby enables efficient arrangement of the first capacitor  70 , the first choke coil  100 , the second capacitor  80 , and the second choke coil  102  to be achieved in the noise suppression device  50 . 
     Moreover, the third capacitor  90  is disposed between the first choke coil  100  and the second choke coil  102 , in an arrangement in which the first capacitor  70  and the second capacitor  80  overlap (are superimposed on) the third capacitor  90  each other in the up-down direction within the height range of the choke coil height (the long axial line) direction. This thereby enables the third capacitor  90  to be mounted to the noise suppression device  50 , while suppressing the noise suppression device  50  from becoming larger in the radial direction of the housing  14 . 
     The noise suppression device  50  is housed in the connector cap  40  and fixed to the connector cap  40 . Due thereto, in a case in which, for example, the noise suppression device  50  is omitted according to specification of the connector cap  40 , by modifying the connector cap  40 , this specification of the washer pump can be easily handled. In such a situation, the housing  14  can be used as a common component. 
     Moreover, it is also possible to easily change to a noise suppression device  50  of a different specification by changing the noise suppression device  50 , in the connector cap  40 , in which the power supply side relay terminal members  110  and  112  are plug-connected to the power supply terminals  44  and  46  of the connector cap  40 . Such a case enables not only the housing  14 , but also the connector cap  40 , to be used as a common component. 
     In the present exemplary embodiment the stopper portion  58  are integrally formed to the base portion  54  in the noise suppression device  50 . Alternatively, the stopper portion  58  and the base portion  54  may be configured as separate bodies. For example, the stopper portion  58  may be configured from metal, and the stopper portion  58  and the base portion  54  then integrated together. 
     In the present exemplary embodiment the engaging tabs  60  are integrally formed to the base portion  54  in the noise suppression device  50 . Alternatively, the engaging tabs  60  and the base portion  54  may be configured as separate bodies. For example, the engaging tabs  60  may be configured from metal, and the engaging tabs  60  and the base portion  54  then integrated together. 
     In the noise suppression device  50  of the present exemplary embodiment, as described above, in the first capacitor  70 , due to the stopper portion  58  abutting the one end portion  72 A of the first capacitor  70 , the position in the first direction of the first capacitor  70  with respect to the holder  52  is set with reference to the one end portion  72 A of the first element body  72 , as a result, the press-fit allowance LB of the first terminals  76 A and  76 B is secured (insured) when the first terminals  76 A and  76 B are press-fit connected to the connection portion  118 A and the connecting portion  114 A, enabling a good press-fit to be achieved of the first terminals  76 A and  76 B into the connection portion  114 A and the connecting portion  118 A (similar applies to the second capacitor  80 ). Accordingly, in the noise suppression device  50  of the present exemplary embodiment, configuration can be made without the engaging tabs  60 , or with another configuration in place of the engaging tabs  60 . 
     In the present exemplary embodiment, a single outlet  28  is formed to the housing  14 , and the washer pump  10  is configured in what is referred to as a single outlet pump. Alternatively, the housing  14  may be formed with a pair of outlets  28 , so as to configure the washer pump  10  in what is referred to as a double-outlet pump, with the washer liquid selectively switchable between ejection from the pair of outlets  28  by switching the rotation direction of the motor  30  (the impeller  38 ). 
     Explanation follows regarding an earth terminal member (a ground terminal member)  218  serving as a “terminal member” according to a second exemplary embodiment, with reference to the drawings. The earth terminal member  218  is applied to a noise suppression device  250  mounted to a vehicle washer pump device  210  (referred to below as washer pump  210 ) serving as a “pump device”. The earth terminal member  218  corresponds to the earth terminal member  118  of the first exemplary embodiment, but some parts of the configuration of the earth terminal member  218  are different from that of the earth terminal member  118 . The washer pump  210  of the present exemplary embodiment is similar to the washer pump  10  of the first exemplary embodiment, except in the earth terminal member  218  and a part of the configuration relating to the earth terminal member  218 . The same reference numerals are appended to locations and portions of the washer pump  210  of the present exemplary embodiment that are the same as those of the washer pump  10  of the first exemplary embodiment, and detailed explanation will be omitted thereof. Explanation follows regarding earth terminal member  218 , mainly focusing on the portions that differ from in the washer pump  10  of the first exemplary embodiment. 
     As illustrated in  FIG. 10 , in the present exemplary embodiment, the first terminal  76 A of the first capacitor  70  is configured as an earth terminal. 
     Further, the second terminal  86 A of the second capacitor  80  is also configured as an earth terminal. 
     As illustrated in  FIG. 11 , the earth terminal member  218  is configured from a conductive metal plate member, and is retained by the base portion  54 . 
     The earth terminal member  218  extends substantially in the up-down direction and in the first direction, and a connection portion  120  is formed at an upper end portion of the earth terminal member  218 . 
     The first terminal  76 A of the first capacitor  70  and the second terminal  86 A of the second capacitor  80  are connected to the connection portion  120 , and the lower end portion of the earth terminal member  218  is connected to ground. Explanation is given below regarding a specific configuration of the earth terminal member  218 , and regarding connection of the earth terminal member  218  to the first terminal  76 A and the second terminal  86 A. 
     As illustrated in  FIG. 10 , the connection portion  114 A is positioned at the second direction one side with respect to the connection portion  120  of the earth terminal member  218 , disposed with its plate thickness direction along the first direction and disposed on the second reference line L 2  in plan view. 
     The connecting portion  116 A is positioned at the second direction another side with respect to the connection portion  120  of the earth terminal member  218 , disposed with its thickness direction along the first direction, and disposed on the second reference line L 2  in plan view. 
     Earth Terminal Member  218   
     As illustrated in  FIG. 13  and  FIG. 14A  to  FIG. 14C , the earth terminal member  218  is formed by bending processing a plate member which is cut out in an elongated shape of specific profile. Specifically, the connection portion  120  is formed by bending a portion which is at one side in the length direction (the arrow C direction side in  FIG. 14A ) of the earth terminal member  218  (the above mentioned plate member) back on itself. Namely, the connection portion  120  is configured by two plate tabs side-by-side in the plate thickness direction. A portion at one length direction side of the connection portion  120  configures a first connection tab  120 A serving as a “connection tab”, and a portion at another length direction side of the connection portion  120  configures a second connection tab  120 B serving as a “connection tab”. The width direction (plate face direction) of the first connection tab  120 A and the second connection tab  120 B is accordingly coincided with (oriented in) the width direction of the earth terminal member  218 . The portion bent over at the upper end portions of each of the first connection tab  120 A and the second connection tab  120 B configures a bent portion  128 . In a state in which the earth terminal member  218  is assembled to the base portion  54 , the earth terminal member  218  is disposed with its length direction along the first direction, and the width direction of the earth terminal member  218  is disposed along the second direction. In this state, the width direction central line of the earth terminal member  218  is coincided with (aligned with) the first reference line L 1 . 
     As illustrated in  FIG. 13 , an anchor tab  122  is integrally formed at a width direction central portion of the lower end portion of the first connection tab  120 A. The anchor tab  122  extends toward the lower side from the first connection tab  120 A. A pair of hook portions  122 A is formed to the leading end portion of the anchor tab  122 . The hook portions  122 A project out from the anchor tab  122  to the outsides in the width direction of the first connection tab  120 A. 
     Moreover, as illustrated in  FIG. 14B  and  FIG. 14C , a fixing portion  124  which is bent into a substantially inverted L-shaped profile is integrally formed to a lower end portion of the second connection tab  120 B. More specifically, the fixing portion  124  is configured including a first fixing wall  124 A extending from the lower end of the second connection tab  120 B to the first direction another side, and a second fixing wall  124 B extending from the leading end of the first fixing wall  124 A to the lower side. The second fixing wall  124 B is disposed so as to face the anchor tab  122  along the first direction. 
     A ground connection portion  126  which is bent into a substantially inverted L-shaped profile is integrally formed to a lower end portion of the second fixing wall  124 B. More specifically, the ground connection portion  126  is configured including a coupling wall  126 A extending from the lower end of the second fixing wall  124 B toward the first direction another side, and a ground connection tab  126 B extending from the leading end of the coupling wall  126 A toward the lower side. The width dimension of the ground connection portion  126  is set so as to be smaller than the width dimension of the fixing portion  124 , and the lower end portion of the ground connection tab  126 B is connected to ground. More specifically, configuration is made such that, in the assembled state of the noise suppression device  250  to the motor  30 , the lower end portion of the ground connection tab  126 B contacts a motor housing (made from metal) of the motor  30 . 
     The earth terminal member  218  is assembled to the base portion  54  from the upper side. More specifically, as illustrated in  FIG. 16  and  FIG. 17 , a first insertion hole  64  is formed to the base portion  54 , for inserting the ground connection portion  126  and the second fixing wall  124 B of the earth terminal member  218  into. The first insertion hole  64  is formed with a substantially T shaped profile (see  FIG. 17 ) with its length direction along the first direction. A second insertion hole  66  is also formed to the base portion  54  on the first direction one side with respect to the first insertion hole  64 , in a configuration such that the anchor tab  122  is inserted into the second insertion hole  66 . A portion of the base portion  54  between the first insertion hole  64  and the second insertion hole  66  configures a fixed portion  68 . Namely, configuration is made such that, in the assembled state of the earth terminal member  218  to the base portion  54 , the fixed portion  68  is clamped (sandwiched) between the anchor tab  122  and the second fixing wall  124 B of the earth terminal member  218 . Configuration is made such that in this state the first fixing wall  124 A of the earth terminal member  218  abuts the upper face of the fixed portion  68  (see  FIG. 16 ). 
     As illustrated in  FIG. 17 , a groove  68 A opening to the second insertion hole  66  side is formed at one side face (the face on the first direction one side) of the fixed portion  68 . The groove  68 A pierces through in the up-down direction. The anchor tab  122  is disposed in the groove  68 A in the assembled state of the earth terminal member  218 . Namely, the thickness dimension Ti of the fixed portion  68  except for at the groove  68 A (see  FIG. 16 ) is set larger than the distance T 2  between the second fixing wall  124 B and the anchor tab  122  (see  FIG. 16 ). A step  68 B is formed in the lower edge portion of the one side face of the fixed portion  68 , open toward the lower side. The step  68 B is in communication with the groove  68 A. Configuration is made such that the hook portions  122 A are disposed in the step  68 B in the assembled state of the earth terminal member  218  (see  FIG. 16 ). Thus movement of the earth terminal member  218  to both sides in the first direction is restricted by the groove  68 A, and movement of the earth terminal member  218  toward the upper side is restricted by the step  68 B. The cross-section position of the fixed portion  68  is illustrated for convenience in  FIG. 16  displaced to the second direction another side with respect to the cross-section position of the earth terminal member  218 . 
     As illustrated in  FIG. 16 , a sloping portion  68 C is formed at an upper portion of the one side face of the fixed portion  68 . The sloping portion  68 C slopes toward the first direction another side on progression toward the upper side as viewed from the second direction. Configuration is accordingly made such that during assembly of the earth terminal member  218  to the fixed portion  68 , the hook portions  122 A of the anchor tab  122  are guided by the sloping portion  68 C such that the anchor tab  122  and the first connection tab  120 A are resiliently deformed in the first direction one side for the bent portions  128  as base point. The anchor tab  122  and the first connection tab  120 A then displace to the first direction another side due to the hook portions  122 A being disposed in the step  68 B, such that the earth terminal member  218  is fixed to the base portion  54 . 
     As illustrated in  FIG. 10  and  FIG. 15 , a first connecting groove  130  and a second connecting groove  140  are formed in the connection portion  120  for connecting the first terminal  76 A of the first capacitor  70  and the second terminal  86 A of the second capacitor  80 . The first connecting groove  130  and the second connecting groove  140  are formed with slit profiles open toward the upper side, and are disposed in the vicinity of each other in a row in the width direction (the plate face direction) of the connection portion  120 . More specifically, as illustrated in  FIG. 10 , the first connecting groove  130  is disposed, so as to correspond to the first terminal  76 A of the first capacitor  70 , at the second direction another side with respect to the axial line AL 1  of the base portion  54 . The second connecting groove  140  is disposed, so as to correspond to the second terminal  86 A of the second capacitor  80 , at the second direction one side with respect to the axial line AL 1  of the base portion  54 . 
     As illustrated in  FIG. 9 , and  FIGS. 14A and 14C , the first connecting groove  130  is configured including a first press-fit groove  132  formed in the second connection tab  120 B, and a first insertion groove  134  formed in the first connection tab  120 A. The first insertion groove  134  and the first press-fit groove  132  are disposed facing each other along the first direction, with the width direction central line of the first insertion groove  134  coincided with (aligned with) the width direction central line of the first press-fit groove  132 . Namely, in an expanded state (in a state of not being bend-processed) of the earth terminal member  218 , the first insertion groove  134  and the first press-fit groove  132  are disposed at positions in the length direction of the earth terminal member  218  symmetrical to each other about a bend line  128 A of the bent portions  128  ( FIG. 14A ). 
     The groove width dimension of the first press-fit groove  132  is set to be slightly smaller than the diameter of the first terminal  76 A, and the groove width dimension of the first insertion groove  134  is set to be larger than the diameter of the first terminal  76 A. Thus when the first terminal  76 A is connected (inserted) into the first connecting groove  130 , the first terminal  76 A is press-fit connected to the first press-fit groove  132 , and is inserted into the first insertion groove  134  in a non-press-fit state. Namely, the first terminal  76 A is connected to the second connection tab  120 B. 
     Moreover, a pair of taper portions  132 A as “first taper portions” are formed to the opening portion of the first press-fit groove  132 , each sloping toward the groove width direction outside on progression toward the upper side. A pair of taper portions  134 A as “second taper portions” are formed to the opening portion of the first insertion groove  134 , each sloping toward the groove width direction outside on progression toward the upper side. In the expanded state of the earth terminal member  218 , the taper portions  132 A and the taper portions  134 A are disposed in the length direction of the earth terminal member  218  at positions symmetrical to each other about the bend line  128 A (see  FIG. 14A ). 
     The second connecting groove  140  is configured including a second press-fit groove  142  formed to the first connection tab  120 A, and a second insertion groove  144  formed to the second connection tab  120 B. The second press-fit groove  142  and the second insertion groove  144  are disposed facing each other along the first direction, with the width direction central line of the second press-fit groove  142  coincided with (aligned with) the width direction central line of the second insertion groove  144 . Namely, in the expanded state of the earth terminal member  218 , the second press-fit groove  142  and the second insertion groove  144  are disposed in the length direction of the earth terminal member  218  at positions symmetrical to each other about the bend line  128 A (see  FIG. 14A ). 
     The groove width dimension of the second press-fit groove  142  is set to be slightly smaller than the diameter of the second terminal  86 A, and the groove width dimension of the second insertion groove  144  is set to be larger than the diameter of the second terminal  86 A. Thus when the second terminal  86 A is connected (inserted) into the second connecting groove  140 , the second terminal  86 A is press-fit connected to the second press-fit groove  142 , and is inserted into the second insertion groove  144  in a non-press-fit state. Namely, the second terminal  86 A becomes connected to the first connection tab  120 A. 
     Moreover, a pair of taper portions  142 A as “first taper portions” are formed to the opening portion of the second press-fit groove  142 , each sloping toward the groove width direction outside on progression toward the upper side. A pair of taper portions  144 A as “second taper portions” are formed to the opening portion of the second insertion groove  144 , each sloping toward the groove width direction outside on progression toward the upper side. In the expanded state of the earth terminal member  218 , the taper portions  142 A and the taper portions  144 A are disposed in the length direction of the earth terminal member  218  at positions symmetrical to each other about the bend line  128 A (see  FIG. 14A ). 
     A portion of the first connection tab  120 A, which is between the first insertion groove  134  and the second press-fit groove  142  configures a partition portion  150 , and A portion of the second connection tab  120 B, which is between the first press-fit groove  132  and the second insertion groove  144  configures a partition portion  152 . Thus in the first connection tab  120 A, the first insertion groove  134  is disposed adjacent in the width direction of the connection portion  120  to the second press-fit groove  142 , with the partition portion  150  being therebetween. In the second connection tab  120 B, the second insertion groove  144  is disposed adjacent in the width direction of the connection portion  120  to the first press-fit groove  132 , with the partition portion  152  being therebetween. 
     As illustrated in  FIG. 14A , in the expanded state of the earth terminal member  218 , the first connecting groove  130  and the second connecting groove  140  are formed by a single hole  154 . Namely, a coupling portion  156  that couples the first connecting groove  130  and the second connecting groove  140  is formed between the partition portion  150  and the partition portion  152 , and the hole  154  is formed with a substantially H-shaped profile. The first connection tab  120 A and the second connection tab  120 B are thereby coupled together at both width direction end portions of the connection portion  120 . More specifically, the first connection tab  120 A and the second connection tab  120 B are coupled at the width direction outsides of the connection portion  120  with respect to the first connecting groove  130  and the second connecting groove  140 . The coupled portions configure coupling portions  158 , and the bent portions  128  are formed by bending processing of the coupling portions  158 . Moreover, the hole  154  is shaped so as to have point symmetry about a central point CP where the width direction central line of the connection portion  120  (namely the first reference line L 1 ) and the bend line  128 A intersect. In other words, a configuration is achieved in which the first connecting groove  130  and the second connecting groove  140  have point symmetry about the central point CP. 
     As explained above, in the earth terminal member  218  of the present exemplary embodiment, the second terminal  86 A is connected to the first connection tab  120 A, and the first terminal  76 A is connected to the second connection tab  120 B. Namely, in the present exemplary embodiment, the number of connection tabs of the connection portion  120  are set so as to correspond to the number of terminals to be connected to the connection portion  120  (2 in the present exemplary embodiment), with a one-to-one correspondence between the connection tabs and the terminals (the first connection tab  120 A corresponds to the second terminal  86 A, and the second connection tab  120 B corresponds to the first terminal  76 A). The press-fit groove for press-fitting the corresponding terminal at each of the connection tabs is formed only at one location, and the press-fit grooves are disposed so as to be displaced from each other in the width direction of the connection portion  120 . In each of the connection tabs, the insertion groove is formed into which the terminal which is press-fitted in the another connection tab is inserted. 
     Explanation follows regarding operation and advantageous effects of the present exemplary embodiment. 
     In the noise suppression device  250 , when the first terminal  76 A of the first capacitor  70  and the second terminal  86 A of the second capacitor  80  are being connected to the connection portion  120  of the earth terminal member  218 , the first terminal  76 A is inserted into the first connecting groove  130 , and the second terminal  86 A is inserted into the second connecting groove  140 . 
     In the connection portion  120 , the second press-fit groove  142  is formed in the first connection tab  120 A, and the first press-fit groove  132  is formed in the second connection tab  120 B. The first press-fit groove  132  and the second press-fit groove  142  are disposed displaced from each other in the width direction of the earth terminal member  218 . The first terminal  76 A (the second terminal  86 A) is press-fitted into the first press-fit groove  132  (the second press-fit groove  142 ). In the connection portion  120 , the first insertion groove  134  is formed in the first connection tab  120 A, and the second insertion groove  144  is formed in the second connection tab  120 B. The first insertion groove  134  (the second insertion groove  144 ) is adjacent to the second press-fit groove  142  (the first press-fit groove  132 ). The first terminal  76 A (the second terminal  86 A) is inserted into the first insertion groove  134  (the second insertion groove  144 ). In the connection portion  120 , the connection tabs into which the first terminal  76 A and the second terminal  86 A are respectively press-fit are accordingly different to each other. This thereby enables a change in the groove width dimension of the second press-fit groove  142  (the first press-fit groove  132 ), arising from displacement (deformation) of the second connection tab  120 B (the first connection tab  120 A), to be suppressed, even if the second connection tab  120 B (the first connection tab  120 A) displaces (deforms) when the first terminal  76 A (the second terminal  86 A) is press-fitted into the first press-fit groove  132  (the second press-fit groove  142 ). The first terminal  76 A can accordingly be press-fit connected to the first press-fit groove  132 , and the second terminal  86 A can be press-fit connected to the second press-fit groove  142 . This thereby enables a good connection of the first terminal  76 A and the second terminal  86 A to the earth terminal member  218 . 
     More detail is given below regarding this point. Namely, due to the groove width dimension of the first press-fit groove  132  being smaller than the diameter dimension of the first terminal  76 A, as illustrated in  FIG. 9 , when the first terminal  76 A is being press-fit into the first press-fit groove  132 , force acts on the earth terminal member  218  to expand the first press-fit groove  132  toward the groove width direction outsides (in the arrow E direction and the arrow F direction in  FIG. 9 ). The partition portion  152  configuring the first press-fit groove  132  is accordingly displaced to the second insertion groove  144  side (the arrow E direction side in  FIG. 9 ). 
     Thus were both the first press-fit groove  132  and the second press-fit groove  142  to be formed to the second connection tab  120 B on the same plate face (namely a configuration in which the second insertion groove  144  is swapped with the second press-fit groove  142 ), then the groove width dimension of the second press-fit groove  142  would become smaller due to the partition portion  152  displacing to the second press-fit groove  142  side when the first terminal  76 A is press-fitted into the first press-fit groove  132 . It would therefore be difficult to press-fit the second terminal  86 A into the second press-fit groove  142 . 
     In contrast thereto, in the earth terminal member  218  of the present exemplary embodiment, the second press-fit groove  142  is formed at the first connection tab  120 A, and the first press-fit groove  132  is formed at the second connection tab  120 B. Namely, in the present exemplary embodiment, connection tabs are provided to so as to correspond to the number of terminals for connection, with a one-to-one correspondence between the respective connection tabs and terminals. This thereby enables or helps to prevent the groove width dimension of the second press-fit groove  142  (the first press-fit groove  132 ) from getting smaller even if the partition portion  152  (the partition portion  150 ) displaces (deforms) when the first terminal  76 A (the second terminal  86 A) is press-fitted into the first press-fit groove  132  (the second press-fit groove  142 ). 
     Moreover, the first insertion groove  134  is formed at the first connection tab  120 A, and the second insertion groove  144  is formed at the second connection tab  120 B, and the first insertion groove  134  (the second insertion groove  144 ) is disposed adjacent to the second press-fit groove  142  (the first press-fit groove  132 ). This thereby enables displacement of the partition portion  152  (the partition portion  150 ) arising when the first terminal  76 A (the second terminal  86 A) is press-fit into the first press-fit groove  132  (the second press-fit groove  142 ) to be absorbed by the second insertion groove  144  (the first insertion groove  134 ), and enables the second terminal  86 A (the first terminal  76 A) to be disposed inside the second insertion groove  144  (the first insertion groove  134 ). Due to the above, a good connection of the first terminal  76 A and the second terminal  86 A to the earth terminal member  218  can be achieved even in a case in which the first terminal  76 A and the second terminal  86 A are disposed in the vicinity of each other. 
     Moreover, the first connection tab  120 A and the second connection tab  120 B are coupled together by the bent portions  128 . This thereby enables the earth terminal member  218  to be configured from single metal plate member, and for the first connection tab  120 A and the second connection tab  120 B to be formed by bending processing of the plate member. This thereby enables the configuration of the earth terminal member  218  to be simplified in comparison to a case, for example, in which the first connection tab  120 A and the second connection tab  120 B are coupled together such as by welding, and enables an increase in cost of the earth terminal member  218  to be suppressed. 
     Moreover, the first terminal  76 A and the second terminal  86 A configure the respective earth terminals of the first capacitor  70  and the second capacitor  80 , and are connected to the earth terminal member  218 . This thereby enables the earth terminal member  218  to be configured as a common earth (ground) contact for the first capacitor  70  and the second capacitor  80 . 
     In the earth terminal member  218 , the bent portions  128  are disposed at the connection portion  120  width direction outsides of the first connecting groove  130  and the second connecting groove  140 . Namely, the partition portion  150  and the partition portion  152  are not coupled together in the connection portion  120 . Thus even if the partition portion  152  (the partition portion  150 ) displaces in the width direction of the connection portion  120  when the first terminal  76 A (the second terminal  86 A) is being press-fitted into the first press-fit groove  132  (the second press-fit groove  142 ), this displacement is not transmitted to the partition portion  150  (the partition portion  152 ). This thereby further enables or helps to prevent change in the groove width dimension of the second press-fit groove  142  (first press-fit groove  132 ). As a result, a good press-fit connection of the first terminal  76 A to the first press-fit groove  132  can thereby be achieved, and a good press-fit connection of the second terminal  86 A to the second press-fit groove  142  can also be achieved. 
     In the expanded state of the earth terminal member  218 , the first insertion groove  134  (the second insertion groove  144 ) and the first press-fit groove  132  (the second press-fit groove  142 ) are disposed at positions symmetrical to the bend line  128 A of the bent portion  128 . This thereby enables the first insertion groove  134  (the second insertion groove  144 ) and the first press-fit groove  132  (the second press-fit groove  142 ) to be easily configured to correspond to (align with) each other. 
     Moreover, in the expanded state of the earth terminal member  218 , the taper portions  132 A (the taper portions  142 A) are disposed at positions symmetrical about the bend line  128 A of the bent portion  128  to the taper portions  134 A (the taper portions  144 A). The taper portions  132 A (the taper portions  142 A) and the taper portions  134 A (taper portions  144 A) can accordingly be easily configured so as to correspond to (align with) each other. 
     In the present exemplary embodiment, two terminals (the first terminal  76 A and the second terminal  86 A) are connected to the connection portion  120 ; however there may be 3 or more terminals connected to the connection portion  120  according to the embodiment of the noise suppression device  250 . For example, as illustrated in  FIG. 18A , the connection portion  120  may be configured with 3 plates of connection tabs (a first connection tab  120 A, a second connection tab  120 B, and a third connection tab  120 C). In such a case, configuration may be made such that the width direction of the earth terminal member  218  and the width direction of the connection portion  120  may not coincide with each other. Namely, configuration may be made such that a first connecting groove  130 , a second connecting groove  140  and a third connecting groove  160  configure grooves that are open to one side in the width direction of the earth terminal member  218 . The first connecting groove  130 , the second connecting groove  140 , and the third connecting groove  160  are then respectively configured such that there is 1 location of press-fit groove and 2 locations of insertion grooves, and the respective press-fit grooves are disposed displaced in the width direction of the connection portion  120  with respect to each other. In  FIG. 18A  and  FIG. 18B , the reference numeral  162  is appended to the press-fit groove in the third connecting groove  160 , and the reference numeral  164  is appended to the insertion grooves in the third connecting groove  160 . The terminals of the electrical elements inserted into the first connecting groove  130 , the second connecting groove  140 , and the third connecting groove  160  are illustrated in the drawings by double-dotted intermittent lines. 
     Moreover, for example as illustrated in  FIG. 18B , similarly to in the present exemplary embodiment, the connection portion  120  may be configured by two plates of connection tabs (the first connection tab  120 A and the second connection tab  120 B), and the press-fit groove  162  of the third connecting groove  160  formed in the second connection tab  120 B, in addition to forming the insertion groove  164  of the third connecting groove  160  in the first connection tab  120 A. Namely, a configuration may be adopted in which press-fit grooves and insertion grooves are arranged in each of the connection tabs alternately to each other on progression along the width direction of the connection tabs. In such a case, deformation of a partition portion when a terminal is being press-fitted into a press-fit groove is absorbed by the insertion groove, thereby enabling or helping to prevent change in the groove width dimension of the press-fit grooves. 
     In the present exemplary embodiment, the first connection tab  120 A and the second connection tab  120 B of the connection portion  120  are integrated together by the bent portion  128  of the coupling portion  158 . However the first connection tab  120 A and the second connection tab  120 B may be integrated together by welding or the like. 
     In the present exemplary embodiment, the coupling portion  158  of the connection portion  120  is formed at the upper end portion of both the first connection tab  120 A and the second connection tab  120 B. However the coupling portion  158  may be formed to one of the outside end portions in the width direction of the first connection tab  120 A and the second connection tab  120 B. 
     In the present exemplary embodiment, the earth terminal member  218  is applied to the noise suppression device  250  of washer pump  210 . The earth terminal member  218  may however be applied to another device. For example, the earth terminal member  218  may be applied to a surge absorption device or the like installed in a vehicle wiper device.
