Title: Terminal and wire with terminal

Description:
TECHNICAL FIELD 
     The present disclosure relates to a terminal and a wire with terminal. 
     BACKGROUND 
     Conventionally, a wire with terminal is known in which a terminal is connected to a core wire exposed from an end of a wire. Such a terminal may include, for example, a crimping portion to be crimped to the core wire exposed form the end of the wire from outside. 
     The above terminal is crimped to the wire, for example, as follows. First, a metal plate material is press-worked to form the terminal having a predetermined shape. Subsequently, the terminal is placed on a placing part of a lower die located on a lower side, out of a pair of dies relatively movable in a vertical direction. Subsequently, the core wire exposed from the end of the wire is placed on the crimping portion of the terminal. Thereafter, one or both of the pair of dies are moved in directions toward each other, and the crimping portion is sandwiched between a crimping part of the upper die and the placing part of the lower die, whereby the crimping portion is crimped to the core wire of the wire. In the above way, the terminal is connected to the end of the wire (see Patent Document 1).

     DETAILED DESCRIPTION TO EXECUTE THE INVENTION 
     [Description of Embodiments of Present Disclosure] 
     First, embodiments of the present disclosure are listed and described. 
     (1) The present disclosure is directed to a terminal to be connected to a front end part of a wire, the terminal including a terminal body and a slide portion, wherein the terminal body includes a sandwiching portion for sandwiching the wire, the slide portion has a tubular shape to be externally fit to the terminal body, the slide portion includes a pressurizing portion projecting inward from an inner surface of the slide portion, the slide portion is slidable with respect to the terminal body between a non-contact position where the pressurizing portion is not in contact with the sandwiching portion and a contact position forward of the non-contact position, the pressurizing portion being in contact with the sandwiching portion at the contact position, the slide portion has a lower wall, a first side wall extending upward from one side edge of the lower wall and a second sandwiching portion extending upward from the other side edge of the lower wall, a first upper wall extending toward the second side wall via a bent first bent portion is formed on an upper end part of the first side wall and a second upper wall extending toward the first side wall via a bent second bent portion is formed at a position forward of the first upper wall on an upper end part of the second side wall, the first upper wall is formed with a projecting portion projecting outward, and a rear holding portion for receiving a force pushing the projecting portion of the first upper wall from behind is provided on a rear end edge of the second upper wall or a rear end edge of the second bent portion. 
     If the projecting portion is pushed forward by a jig, the first upper wall provided with the projecting portion is pushed forward. Then, a force applied to the first upper wall when the jig pushes the projecting portion forward is received by the rear holding portion of the second upper wall. In this way, the strength of the slide portion can be improved. 
     (2) Preferably, the rear holding portion includes a rear end edge of the second bent portion, and an end part on the second side wall side, out of a front end edge of the first upper wall, serves as a first contact portion for contacting the rear end edge of the second bent portion when the projecting portion of the first upper wall is pushed from behind. 
     If the projecting portion is pushed forward from behind by the jig, the first upper wall moves to turn when viewed from above since a rear end part of the first bent portion functions like a support point. In this way, the first contact portion formed on the second side wall side, out of the front end edge of the first upper wall, comes into contact with the rear holding portion of the second upper wall from behind. Since the second bent portion is bent, the strength of the second bent portion is higher than those of the second side wall and the second upper wall. In this way, the strength of the slide portion can be improved. 
     (3) Preferably, a front holding portion projecting upward is formed at a position forward of the first bent portion on an upper end edge of the first side wall, a second contact portion is provided behind the front holding portion on the second upper wall, and a force applied to the rear holding portion of the second upper wall is received by the second contact portion coming into contact with the front holding portion from behind. 
     If a force is applied to the rear holding portion from behind, the second upper wall moves to turn when viewed from above since a rear end part of the second bent portion functions like a support point. In this way, the second contact portion formed on the second side wall side, out of the second upper wall, comes into contact with the front holding portion of the first upper wall from behind. Since a force received by the second contact portion is received by the front holding portion in this way, the strength of the slide portion can be improved. 
     (4) Preferably, the projecting portion is formed near the first bent portion. 
     If the projecting portion is pushed forward from behind by the jig, the first upper wall moves to turn when viewed from above since the rear end part of the first bent portion functions like a support point. Since the projecting portion is formed near the first bent portion functioning like the support point, the first upper wall hardly rotates when the projecting portion is pushed from behind. In this way, the strength of the slide portion can be improved. 
     (5) Preferably, the projecting portion is formed by bending the first upper wall. 
     Since the projecting portion is formed by bending the first upper wall, a part where a thickness of a metal plate material constituting the projecting portion is thinner than other parts is hardly formed. Since the strength of the projecting portion can be improved in this way, the strength of the slide portion can be improved. 
     (6) Preferably, the slide portion has a third upper wall behind the first upper wall, and the third upper wall is provided with a pressurizing portion. 
     If the projecting portion formed on the first upper wall is pushed from behind, a force applied to this projecting portion is received by the second upper wall located forward of the first upper wall. On the other hand, by providing the third upper wall with the pressurizing portion for pressing the sandwiching portion, a force applied from the sandwiching portion to the pressurizing portion is received by the third upper wall. In this way, a force applied to the slide portion can be dispersed as compared to the case where a force received by the projecting portion and a force received by the pressurizing portion are received by one upper wall. In this way, the strength of the slide portion can be improved. 
     (7) The present disclosure is directed to a wire with terminal including any one of the above terminals and a wire to be connected to the terminal.

The terminal  12  according to this embodiment is a so-called female terminal and the mating terminal is a so-called male terminal. 
     As shown in  FIG.  2   , the tube portion  17  is in the form of a rectangular tube extending in the front-rear direction. The front end of the tube portion  17  is open, so that that the mating terminal is insertable. A resiliently deformable resilient contact piece (not shown) is provided inside the tube portion  17 . The resilient contact piece projects inward from an inner wall of the tube portion  17  and extends in the front-rear direction. The mating terminal inserted into the tube portion  17  presses and resiliently deforms the resilient contact piece. The mating terminal is sandwiched between the inner wall of the tube portion  17  and the resilient contact piece by a resilient force of the resiliently deformed resilient contact piece. In this way, the mating terminal and the terminal  12  are electrically connected. 
     As shown in  FIG.  2   , the wire connecting portion  20  in the form of a rectangular tube is provided behind the tube portion  17 . The upper sandwiching portion  18 A (an example of a sandwiching portion) is provided to extend rearward in a rear end part of the upper wall of the wire connecting portion  20 , and the lower sandwiching portion  18 B (an example of the sandwiching portion) is provided to extend rearward in a rear end part of the lower wall of the wire connecting portion  20 . The upper and lower sandwiching portions  18 A,  18 B have a shape elongated in the front-rear direction. Lengths in the front-rear direction of the upper and lower sandwiching portions  18 A,  18 B are substantially equal. 
     As shown in  FIG.  2   , an upper holding protrusion  23 A projecting downward is provided at a position forward of a rear end part on the lower surface of the upper sandwiching portion  18 A. A lower holding protrusion  23 B projecting upward is provided in a rear end part of the upper surface of the lower sandwiching portion  18 B. The lower and upper holding protrusions  23 B,  23 A are provided at positions shifted in the front-rear direction. 
     The lower surface of the upper sandwiching portion  18 A and the upper surface of the lower sandwiching portion  18 B bite into an oxide film formed on the surface of the core wire  13  and peel off the oxide film, whereby a metal surface of the core wire  13  is exposed. By the contact of this metal surface with the upper and lower sandwiching portions  18 A,  18 B, the core wire  13  and the terminal body  15  are electrically connected. 
     As shown in  FIG.  3   , locking projections  28  projecting outward are formed on side walls of the terminal body  15 . These locking projections  28  are locked to partial lock receiving portions  26  and full lock receiving portions  27  to be described later to hold the slide portion  16  at a partial locking position (an example of a non-contact position) and a full locking position (an example of a contact position). 
     [Slide Portion  16 ] 
     As shown in  FIG.  3   , the slide portion  16  is in the form of a rectangular tube extending in the front-rear direction. The slide portion  16  is formed by press-working a metal plate material into a predetermined shape. An arbitrary metal such as copper, copper alloy, aluminum, aluminum alloy or stainless steel can be appropriately selected if necessary as a metal constituting the slide portion  16 . Although not particularly limited, the slide portion  16  according to this embodiment is made of stainless steel. A plating layer may be formed on the surface of the slide portion  16 . An arbitrary metal such as tin, nickel or silver can be appropriately selected if necessary as a metal constituting the plating layer. 
     As shown in  FIG.  2   , an inner cross-sectional shape of the slide portion  16  is equal to or somewhat larger than an outer cross-sectional shape of a region of the terminal body  15  where the upper and lower sandwiching portions  18 A,  18 B are provided. In this way, the slide portion  16  is disposed outside the region of the terminal body  15  where the upper and lower sandwiching portions  18 A,  18 B are provided. 
     As shown in  FIG.  4   , the slide portion  16  has a lower wall  31 , a right side wall  39  (an example of a first side wall) extending upward from the right side edge of the lower wall  31 , a left side wall  34  (an example of a second side wall) extending upward from the left side edge of the lower wall  31 , and an upper wall  30  covering a space formed by the lower wall  31  and the right and left side walls  39 ,  34 . 
     As shown in  FIG.  4   , the upper wall  30  of the slide portion  16  is divided into three parts in the front-rear direction. Out of the upper wall  30 , a part located near a center in the front-rear direction serves as a first upper wall  30 A. A second upper wall  30 B is provided in front of the first upper wall  30 A. A third upper wall  30 C is provided behind the first upper wall  30 A. 
     As shown in  FIG.  5   , the first upper wall  30 A is formed to extend leftward from a center in the front-rear direction of an upper end part of the right side wall  39 . The right side wall  39  and the first upper wall  30 A are connected via a first bent portion  32 . The first bent portion  32  couples the right side wall  39  and the first upper wall  30 A with the right side wall  39  and the first upper wall  30 A bent substantially at a right angle. 
     As shown in  FIG.  5   , a first overlapping portion  52  formed to extend rightward from a center in the front-rear direction, out of an upper end part of the left side wall  34  is formed below the first upper wall  30 A. The first upper wall  30 A and the first overlapping portion  52  are formed into rectangular shapes having substantially the same size when viewed from above. 
     As shown in  FIG.  6   , the left side wall  34  and the second upper wall  30 B are connected via a second bent portion  33 . The second bent portion  33  couples the left side wall  34  and the second upper wall  30 B with the left side wall  34  and the second upper wall  30 B bent substantially at a left angle. A recess  56  recessed rearward from a front end part is formed on the right side edge of the second upper wall  30 B. A front holding portion  55  provided on an upper end part of the right side wall  39  is disposed in this recess  56 . The front holding portion  55  is shaped to project upward from a region corresponding to the recess  56 , out of the upper end part of the right side wall  39 . 
     As shown in  FIG.  7   , a second overlapping portion  53  shaped to extend leftward from a part behind the front holding portion  55 , out of the upper end part of the right side wall  39 , is provided below the second upper wall  30 B. A left end part of the second overlapping portion  53  serves as an extending portion formed to extend forward. The front end edge of the extending portion is formed to be flush with the front end edge of the slide portion  16 . 
     The third upper wall  30 C is formed to extend leftward from a part behind the first bent portion  32 , out of the upper end part of the right side wall  39 . 
     As shown in  FIG.  2   , a lower pressurizing portion  25 B (an example of a pressurizing portion) projecting upward is provided on the upper surface of the lower wall  31  of the slide portion  16 . An upper pressurizing portion  25 A (an example of the pressurizing portion) projecting downward is provided in a substantially half region in a forward direction from the rear end of the slide portion  16  below the third upper wall  30 C of the slide portion  16 . 
     As shown in  FIG.  4   , the partial lock receiving portions  26  are open at positions near front end parts in the front-rear direction on the left and right side walls  34 ,  39  of the slide portion  16 . Further, the full lock receiving portions  27  are open at positions behind the partial lock receiving portions  26  on the left and right side walls  34 ,  39  of the slide portion  16 . The partial lock receiving portions  26  and the full lock receiving portions  27  are resiliently lockable to the locking projections  28  provided on the left and right side walls  34 ,  39  of the terminal body  15 . 
     With the locking projections  28  of the terminal body  15  and the partial lock receiving portions  26  of the slide portion  16  locked, the slide portion  16  is held at the partial locking position with respect to the terminal body  15  (see  FIG.  8   ). In this state, the upper and lower pressurizing portions  25 A,  25 B of the slide portion  16  are located behind the rear end edges of the upper and lower sandwiching portions  18 A,  18 B of the terminal body  15 . In this way, the upper and lower pressurizing portions  25 A,  25 B are respectively not in contact with the upper and lower sandwiching portions  18 A,  18 B and are separated rearward therefrom. Further, in this state, an interval between the upper and lower sandwiching portions  18 A,  18 B is set larger than a diameter of the core wire  13  (see  FIG.  9   ). 
     With the locking projections  28  of the terminal body  15  and the full lock receiving portions  27  of the slide portion  16  locked, the slide portion  16  is located at the full locking position with respect to the terminal body  15 . As shown in  FIG.  2   , in this state, the upper pressurizing portion  25 A of the slide portion  16  is in contact with the upper sandwiching portion  18 A from above the upper sandwiching portion  18 A. Further, the lower pressurizing portion  25 B of the slide portion  16  is in contact with the lower sandwiching portion  18 B from below the lower sandwiching portion  18 B. 
     As described above, the slide portion  16  is slidable in the front-rear direction between the partial locking position and the full locking position while being externally fit to the region of the terminal body  15  where the upper and lower sandwiching portions  18 A,  18 B are provided. 
     As shown in  FIG.  2   , with the slide portion  16  held at the full locking position with respect to the terminal body  15 , the upper pressurizing portion  25 A presses the upper sandwiching portion  18 A from above, whereby the upper sandwiching portion  18 A is deformed downward. Further, the lower pressurizing portion  25 B presses the lower sandwiching portion  18 B from below, whereby the lower sandwiching portion  18 B is deformed upward. In this way, the core wire  13  is sandwiched in the vertical direction by the resiliently deformed upper and lower sandwiching portions  18 A,  18 B with the core wire  13  disposed to extend in the front-rear direction in a space between the upper and lower sandwiching portions  18 A,  18 B and the slide portion  16  held at the full locking position with respect to the terminal body  15 . That is, the upper sandwiching portion  18 A contacts the core wire  13  from above by being pressed downward by the upper pressurizing portion  25 A, and the lower sandwiching portion  18 B contacts the core wire  13  from below by being pressed upward by the lower pressurizing portion  25 B. 
     As shown in  FIG.  2   , with the slide portion  16  held at the full locking position with respect to the terminal body  15 , the upper holding protrusion  23 A of the upper sandwiching portion  18 A presses the core wire  13  from above and the lower holding protrusion  23 B of the lower sandwiching portion  18 B presses the core wire  13  from below. In this way, the core wire  13  is pressed from above by the upper holding protrusion  23 A and pressed from below by the lower holding protrusion  23 B disposed at a position shifted in the front-rear direction from the upper holding protrusion  23 A, thereby being held in a state bent in the vertical direction. Further, the core wire  13  and the terminal  12  are electrically connected also by the upper and lower holding protrusions  23 A,  23 B. 
     As shown in  FIG.  8   , a pair of guiding portions  47  projecting inwardly of the slide portion  16  are provided at positions near a rear end part of the slide portion  16  on the left and right side walls  34 ,  39 . The guiding portions  47  are formed to become narrower from rear to front. The core wire  13  is guided into the slide portion  16  by sliding in contact with the inner surfaces of the guiding portions  47 . 
     The first upper wall  30 A is formed by bending leftward a part near the center in the front-rear direction of the upper edge part of the right side wall  39  of the slide portion  16 . The first upper wall  30 A has a substantially rectangular shape when viewed from above. 
     As shown in  FIG.  4   , a projecting portion  46  projecting upward is provided in a right region of the first upper wall  30 A. In other words, the projecting portion  46  is formed near the first bent portion  32  of the first upper wall  30 A. The projecting portion  46  according to this embodiment is formed continuously with the first bent portion  32 . The projecting portion  46  is formed by bending the first upper wall  30 A. The projecting portion  46  is formed to extend in the front-rear direction from a front end part to a rear end part of the first upper wall  30 A. When viewed from behind, the projecting portion  46  is in the form of a rectangular groove open downward. The projecting portion  46  is formed to have a uniform thickness. The uniform thickness means not only a strictly uniform thickness, but also a thickness substantially regarded as uniform even if not being strictly uniform. In other words, the projecting portion  46  is not formed with an extremely thin part. The slide portion  16  is movable forward by pushing the projecting portion  46  forward. 
     A structure for pushing the projecting portion  46  is not particularly limited. For example, a known jig  45  can be used. Further, without limitation to the jig  45 , the projecting portion  46  may be, for example, pushed by a manufacturing facility provided with an actuator for pushing the projecting portion  46 . 
     As shown in  FIG.  4   , a part near a left end part of the front end edge of the first upper wall  30 A serves as a first contact portion  50  for contacting the rear end edge of the second bent portion  33  when the projecting portion  46  is pushed from behind by the jig  45 . On the other hand, the rear end edge of the second bent portion  33  serves as a rear holding portion  54 . If the projecting portion  46  is pushed from behind by the jig  45 , the first contact portion  50  contacts the rear holding portion  54  from behind, whereby a force for pushing the projecting portion  46  of the first upper wall  30 A from behind is received by the rear holding portion  54 . 
     As shown in  FIG.  4   , a rear end part of the recess  56  formed on the second upper wall  30 B serves as a second contact portion  51  for contacting the front holding portion  55  from behind when the first contact portion  50  contacts the rear holding portion  54  of the second upper wall  30 B from behind. The second contact portion  51  is located behind the front holding portion  55 . 
     [Connection Process of Wire  11  and Terminal  12 ] 
     Next, an example of a connection process of the wire  11  and the terminal  12  is described. The connection process of the wire  11  and the  12  is not limited to the one described below. 
     The terminal body  15  and the slide portion  16  are formed by a known method. The slide portion  16  is assembled with the terminal body  15  from behind. The front end edge of the slide portion  16  comes into contact with the locking projections  28  of the terminal body  15  from behind and the side walls of the slide portion  16  are expanded and deformed. If the slide portion  16  is further pushed forward, the side walls of the slide portion  16  are restored and the partial lock receiving portions  26  of the slide portion  16  are locked to the locking projections  28  of the terminal body  15 . In this way, the slide portion  16  is held at the partial locking position with respect to the terminal body  15  (see  FIG.  8   ). In this way, the terminal  12  is obtained. 
     The core wire  13  of the wire  11  is exposed by stripping the insulation coating  14  by a known method. 
     As shown in  FIG.  9   , if the wire  11  is pushed forward through the rear end part of the slide portion  16 , a front end part of the core wire  13  is introduced into the slide portion  16 . The core wire  13  comes into contact with the guiding portions  47  of the slide portion  16 , thereby being guided into the slide portion  16 . If the wire  11  is further pushed forward, the front end part of the core wire  13  enters the terminal body  15  and reaches the space between the upper and lower sandwiching portions  18 A,  18 B. 
     With the slide portion  16  held at the partial locking position with respect to the terminal body  15 , the interval between the upper and lower sandwiching portions  18 A,  18 B is set larger than the outer diameter of the core wire  13 . 
     Subsequently, as shown in  FIG.  10   , the jig  45  is brought into contact with the projecting portion  46  from behind to slide the slide portion  16  forward. The slide portion  16  is moved relatively forward with respect to the terminal body  15 . At this time, the locking of the locking projections  28  of the terminal body  15  and the partial lock receiving portions  26  of the slide portion  16  is released and the side walls of the slide portion  16  ride on the locking projections  28  to be expanded and deformed. 
     If the slide portion  16  is moved forward, the side walls of the slide portion  16  are restored and the locking projections  28  of the terminal body  15  and the full lock receiving portions  27  of the slide portion  16  are resiliently locked. In this way, the slide portion  16  is held at the full locking position with respect to the terminal body  15 . 
     As shown in  FIG.  9   , successively from a front side, the second overlapping portion  53  is disposed below the second upper wall and the first overlapping portion  52  is disposed below the first upper wall. The lower surface of the second overlapping portion  53 , that of the first overlapping portion  52  and that of a front end part of the third upper wall are formed to be substantially flush with each other. In this way, the upper sandwiching portion is guided by the lower surface of the second overlapping portion  53  and that of the first overlapping portion  52  inside the slide portion  16  and smoothly moves to the lower surface of the front end party of the third upper wall. 
     With the slide portion  16  held at the full locking position with respect to the terminal body  15 , the upper pressurizing portion  25 A of the slide portion  16  comes into contact with the upper sandwiching portion  18 A of the terminal body  15  from above and presses the upper sandwiching portion  18 A downward. Further, the lower pressurizing portion  25 B of the slide portion  16  comes into contact with the lower sandwiching portion  18 B of the terminal body  15  from below and presses the lower sandwiching portion  18 B upward. In this way, the core wire  13  is vertically sandwiched by the upper and lower sandwiching portions  18 A,  18 B. 
     As shown in  FIG.  2   , the core wire  13  is sandwiched by the lower surface of the upper sandwiching portion  18 A and the upper surface of the lower sandwiching portion  18 B, whereby the oxide film formed on the surface of the core wire  13  is peeled to expose the metal surface constituting the core wire  13 . By the contact of this metal surface with the upper and lower sandwiching portions  18 A,  18 B, the wire  11  and the terminal  12  are electrically connected. 
     In a state vertically sandwiched by the upper and lower sandwiching portions  18 A,  18 B, the core wire  13  is sandwiched by the upper holding protrusion  23 A of the upper sandwiching portion  18 A and the lower holding protrusion  23 B of the lower sandwiching portion  18 B, thereby being held in a state extending in the front-rear direction and bent in the vertical direction. In this way, the core wire  13  can be firmly held, wherefore a holding force for the wire  11  and the terminal  12  can be enhanced if a pulling force acts on the wire  11 . In this way, the wire with terminal  10  is completed. 
     [Functions and Effects of Embodiment] 
     Next, functions and effects of this embodiment are described. The terminal  12  according to this embodiment is connected to the front end part of the wire  11  and includes the terminal body  15  and the slide portion  16 . The terminal body  15  includes the upper and lower sandwiching portions  18 A,  18 B for sandwiching the wire  11 . The slide portion  16  has a tubular shape to be externally fit to the terminal body  15 . The slide portion  16  includes the upper and lower pressurizing portions  25 A,  25 B projecting inwardly from the inner surface of the slide portion  16 . The slide portion  16  is slidable with respect to the terminal body  15  between the partial locking position where the upper and lower pressurizing portions  25 A,  25 B are not in contact with the upper and lower sandwiching portions  18 A,  18 B and the full locking position which is forward of the partial locking position and where the upper and lower pressurizing portions  25 A,  25 B are in contact with the upper and lower sandwiching portions  18 A,  18 B. The slide portion  16  has the lower wall  31 , the right side wall  39  extending upward from the right side edge of the lower wall  31  and the left side wall  34  extending upward from the left side edge of the lower wall  31 . The first upper wall  30 A extending toward the left side wall  34  via the bent first bent portion  32  is formed on the upper end part of the right side wall  39 . The second upper wall  30 B extending toward the right side wall  39  via the bent second bent portion  33  is formed at the position forward of the first upper wall  30 A on the upper end part of the left side wall  34 . The first upper wall  30 A is formed with the projecting portion  46  projecting outward. The rear holding portion  54  for receiving a force pressing the projecting portion  46  of the first upper wall  30 A from behind is provided on the rear end edge of the second upper wall  30 B or the rear end edge of the second bent portion  33 . 
     Further, the wire with terminal  10  according to this embodiment includes the above terminal  12  and the wire  11  to be connected to the terminal  12 . 
     As shown in  FIG.  10   , if the projecting portion  46  is pushed forward by the jig  45 , the first upper wall  30 A provided with the projecting portion  46  is pushed forward. Then, the entire first upper wall  30 A is pushed forward and the front end edge of the first upper wall  30 A contacts the rear holding portion  54  from behind. In this way, a force applied to the first upper wall  30 A when the jig pushes the projecting portion  46  forward is received by the rear holding portion  54  of the second upper wall  30 B. In this way, the strength of the slide portion can be improved. 
     According to this embodiment, the rear holding portion  54  includes the rear end edge of the second bent portion  33  and an end part on the side of the left side wall  34 , out of the front end edge of the first upper wall  30 A, serves as the first contact portion  50  for contacting the rear end edge of the second bent portion  33  when the projecting portion  46  of the first upper wall  30 A is pushed from behind. 
     The first upper wall  30 A is connected to the right side wall  39  via the first bent portion  32  extending in the front-rear direction. Thus, the first upper wall  30 A cannot move straight forward even if being pushed from behind by the jig. Specifically, the rear end part of the first bent portion  32  functions like a support point and substantially turns in a direction indicated by an arrow A when viewed from above. Since the first bent portion  32  extends in the front-rear direction as described above, the first upper wall  30 A does not make a perfectly circular motion. Further, the rear end part of the first bent portion  32  does not serve as an exact center of rotation. 
     If the first upper wall  30 A is pushed from behind by a pressing portion, the first contact portion  50  formed on the side of the second side wall, out of the front end edge of the first upper wall  30 A, comes into contact with the rear holding portion  54  of the second upper wall  30 B from behind. Since the second bent portion  33  is bent, the strength of the second bent portion  33  is higher than those of the second side wall and the second upper wall  30 B. In this way, the strength of the slide portion can be improved. 
     According to this embodiment, the front holding portion  55  projecting upward is formed at the position forward of the first bent portion  32  on the upper end edge of the first side wall, the second upper wall  30 B is provided with the second contact portion  51  behind the front holding portion  55 , and a force applied to the rear holding portion  54  of the second upper wall  30 B is received by the second contact portion  51  coming into contact with the front holding portion  55  from behind. 
     If the rear holding portion  54  of the second upper wall  30 B is pushed from behind by the first contact portion  50  of the first upper wall  30 A, the second upper wall  30 B entirely moves forward. In particular, since the second upper wall  30 B and the left side wall  34  are coupled by the second bent portion  33  extending in the front-rear direction, the second upper wall  30 B cannot move straight forward. Specifically, the rear end part of the second bent portion  33  functions like a support point and moves to substantially turn in a direction indicated by an arrow B when viewed from above. Since the second bent portion  33  extends in the front-rear direction as described above, the second upper wall  30 B does not make a perfectly circular motion. Further, the rear end part of the second bent portion  33  does not serve as an exact center of rotation. 
     If the rear holding portion  54  is pushed from behind by the first contact portion  50 , the second contact portion  51  formed on the side of the second side wall, out of the second upper wall  30 B, comes into contact with the front holding portion  55  of the first upper wall  30 A from behind. Since a force received by the second contact portion  51  is received by the front holding portion  55  in this way, the strength of the slide portion can be improved. 
     According to this embodiment, the projecting portion  46  is formed near the first bent portion  32 . 
     If the projecting portion  46  is pushed forward from behind by the jig, the first upper wall  30 A moves to substantially turn when viewed from above since the rear end part of the first bent portion  32  functions like a support point. Since the projecting portion  46  is formed near the first bent portion  32  functioning like a support point, the first upper wall  30 A hardly turns when the projecting portion  46  is pushed from behind. In this way, the strength of the slide portion can be improved. 
     According to this embodiment, the projecting portion  46  is formed by bending the first upper wall  30 A. 
     Since the projecting portion  46  is formed by bending the first upper wall  30 A, a part where a thickness of the metal plate material constituting the projecting portion  46  is thinner than other parts is hardly formed. Since the strength of the projecting portion  46  can be improved in this way, the strength of the slide portion can be improved. 
     According to this embodiment, the slide portion has the third upper wall behind the first upper wall  30 A, and the third upper wall is provided with the pressurizing portion. 
     If the projecting portion  46  formed on the first upper wall  30 A is pushed from behind, a force applied to this projecting portion  46  is received by the second upper wall  30 B located forward of the first upper wall  30 A. On the other hand, by providing the third upper wall with the pressurizing portion for pressing the sandwiching portion, a force applied from the sandwiching portion to the pressurizing portion is received by the third upper wall. In this way, a force applied to the slide portion can be dispersed as compared to the case where a force received by the projecting portion  46  and a force received by the pressurizing portion are received by one upper wall. In this way, the strength of the slide portion can be improved.
