Title: Sealing and pumping device

Description:
TECHNICAL FIELD 
     The present invention relates to a sealing and pumping device for injecting a sealing agent into a pneumatic tire in order to seal a punctured pneumatic tire, and for supplying compressed air into a pneumatic tire to raise the internal pressure of the pneumatic tire. 
     RELATED ART 
     Recently, sealing and pumping devices are becoming common which, when pneumatic tires (referred to below simply as tires) are punctured, the sealing and pumping devices repair the tire with a sealing agent and pump the internal pressure up to a specific specified pressure, rather than changing the tire or the wheel. The sealing and pumping device described in patent document 1, for example, is a known example of such a sealing and pumping device. 
     This sealing and pumping device is connected to a storage container containing sealing agent, and a foot portion having an installation face is formed to a bottom portion of a sealing agent ejection unit. Stable upright states of the storage container and the sealing agent ejection unit of the sealing and pumping device are secured by the foot portion.

     DISCLOSURE OF THE INVENTION 
     Problem to be Solved by the Invention 
     Due to their convenience, integrated sealing and pumping devices that integrate each device within a single casing are recently becoming common. Integrated sealing and pumping devices such as these are very often normally stored in the storage space of a vehicle, such as in the luggage room, and therefore space saving characteristics, namely compactness, is desired from the standpoint of efficient use of the luggage room. 
     However, when integrated sealing and pumping devices are made compact, there is a certain desirable orientation for ensuring discharge of a sealing agent within a liquid agent container containing the sealing agent (the orientation in which the sealing agent outlet of the liquid agent container faces the bottom in the vertical direction), and since the pressure withstanding ability of the liquid agent container is proportional to the diameter of the liquid agent container, the long narrow shape of the liquid agent container cannot be changed. This leads to a requirement for the integrated sealing and pumping devices to be narrow in thickness. 
     However, since narrow integrated sealing and pumping devices suffer from readily tipping over, a sealing and pumping device that does not readily tip over but nevertheless maintains space saving characteristics is desired in the marketplace. 
     The present invention is made in consideration of the above circumstances and an object thereof is to provide a sealing and pumping device that does not readily tip over, while maintaining the space saving characteristics thereof. 
     Method of Solving the Problem 
     In order to achieve the above object, the sealing and pumping device of claim  1  of the present invention is a sealing and pumping device for injecting a sealing agent into a pneumatic tire by sending compressed air generated by an air supply source through a liquid agent container containing the sealing agent and into the pneumatic tire, the sealing and pumping device including: a casing housing therein at least the air supply source and the liquid agent container; and a tipping suppression member that is provided to the casing so as to be projectable outside from the casing in the width direction thereof, with at least a portion of the tipping suppression member being placed on an installation surface, on which the casing is placed, to suppress tipping over of the casing. 
     Explanation will now be given of the operation of the sealing and pumping device of claim  1 . 
     When repairing a pneumatic tire, first an air-liquid supply tube, which introduces sealing agent or compressed air flowing out from the liquid agent container into the pneumatic tire, is connected to a valve of the pneumatic tire. Compressed air generated in the air supply source is introduced into the liquid agent container, through an air supply path for introducing compressed air from the air supply source into the liquid agent container, and sealing agent inside the container is pushed out from the container by the compressed air. The sealing agent pushed out from the container is supplied into the pneumatic tire through the air-liquid supply tube. 
     When the sealing agent from the liquid agent container ceases coming out, the compressed air is supplied into the pneumatic tire through the air-liquid supply tube. Air supply is halted when the stipulated pressure is achieved and the air-liquid supply tube is removed from the valve of the pneumatic tire. Preparatory running is then performed. The sealing agent thereby fills the puncture hole. After completing preparatory running, the air pressure is checked, and air is put in again if required. Repair of the pneumatic tire is thereby completed. 
     In the sealing and pumping device of claim  1 , by making the tipping suppression member contact the ground surface when the casing is placed on an installation surface (such as a road surface) with the tipping suppression member is in a state projecting out to the outside from the casing in the width direction thereof, the ground contact shape of the casing is made larger than prior to projecting out the tipping suppression member. The sense of stability of the casing is thus increased and tipping over is suppressed. 
     Also, when the tipping suppression member is in a state not projecting outside from the casing in the width direction thereof, there is so no concern of detriment to the space saving characteristics of the casing due to the tipping suppression member, and, for example, storage space within a vehicle can be effectively utilized even when the casing is stored therein. The sealing and pumping device of claim  1  can therefore suppress tipping over while maintaining space saving characteristics. 
     A sealing and pumping device of claim  2  of the present invention is the sealing and pumping device of claim  1 , wherein: a storage portion is formed in the casing for storing at least one of a power cable used for supplying power to the air supply source, and/or an air-liquid supply tube that introduces sealing agent or compressed air flowing out from the liquid agent container into the pneumatic tire; and the tipping suppression member is a lid covering the storage portion. 
     Explanation will now be given of the operation of the sealing and pumping device of claim  2 . 
     By combining the tipping suppression member, for suppressing tipping over of the casing, with us as the lid of the storage portion, for storing at least one of the power cable and/or the air-liquid supply tube, the number of components is reduced, and a reduction in cost of the sealing and pumping device is achieved. 
     A sealing and pumping device of claim  3  is the sealing and pumping device of claim  1  or claim  2 , wherein the tipping suppression member is detachably mounted to the casing. 
     Explanation will now be given of the operation of the sealing and pumping device of claim  3 . 
     Since the tipping suppression member is detachably mounted the casing can be suppressed from tipping over by mounting the tipping suppression member so as to project outside from the casing in the width direction thereof, and the space saving characteristics can be maintained by mounting the tipping suppression member so as not to project outside from the casing. Consequently, by means of a simple structure, tipping over can be suppressed while maintaining space saving characteristics. 
     A sealing and pumping device of claim  4  of the present invention is the sealing and pumping device of claim  1  or claim  2 , wherein the tipping suppression member is rotatably supported on the casing. 
     Explanation will now be given of the operation of the sealing and pumping device of claim  4 . 
     Since the tipping suppression member is rotatably supported on the casing, the casing can be suppressed from tipping over by rotating the tipping suppression member so as to project outside from the casing in the width direction thereof, and the space saving characteristics can be maintained by rotating the tipping suppression member so as not to project outside from the casing. Consequently, by means of a simple structure, tipping over can be suppressed while maintaining the space saving characteristics. In addition, since the tipping suppression member is rotatably supported on the casing, there is no concern of the tipping suppression member being lost or the like. 
     The sealing and pumping device of claim  5  is the sealing and pumping device of claim  1  or claim  2 , wherein the tipping suppression member is slidably supported on the casing. 
     Explanation will now be given of the operation of the sealing and pumping device of claim  5 . 
     Since the tipping suppression member is slidably supported on the casing, the casing can be suppressed from tipping over by sliding the tipping suppression member so as to project outside from the casing in the width direction thereof, and the space saving characteristics can be maintained by sliding the tipping suppression member so as not to project outside from the casing. Consequently, by means of a simple structure, tipping over can be suppressed while Maintaining the space saving characteristics. In addition, since the tipping prevention member is slidably supported on the casing, there is no concern of the tipping prevention member being lost or the like. 
     Effect of the Invention 
     As explained above, the sealing and pumping device of the present invention can suppress tipping over, while maintaining space saving characteristics.

     BEST MODE OF IMPLEMENTING THE INVENTION 
     First Exemplary Embodiment 
     Explanation will now be given of a sealing and pumping device according to a first exemplary embodiment, with reference to  FIGS. 1 to 7 . Note that in the drawings arrow Z indicates the top-bottom direction of the sealing and pumping device, arrow X indicates the front-rear direction (width direction) of the sealing and pumping device, and the arrow Y indicates the left-right direction (a direction orthogonal to the width direction). 
     A sealing and pumping device  10  according to the first exemplary embodiment of the present invention, as shown in  FIG. 1  and  FIG. 2 , is a device for, when a pneumatic tire (referred to below simply as tire) mounted to a vehicle, such as a car or the like, is punctured, repairing the tire with a sealing agent and increasing (pumping up) the internal pressure to a specific specified pressure, instead of changing the tire and the wheel. 
     The sealing and pumping device  10  is provided with a casing  11 . A compressor unit  12 , an injection unit  20 , and a liquid agent container  18  connected to the injection unit  20 , are disposed within this casing  11 . The casing  11  is a narrow casing that is longer in the arrow Y direction than in the arrow X direction. 
     A motor, air compressor, power circuit, control board and the like are disposed within the compressor unit  12 , and a power source cable  14  is provided extending from the power circuit to outside of the unit. For example, a power source can be supplied to the motor etc. from a battery mounted to a vehicle through the power circuit, by inserting a plug  15  provided at the leading end of the power source cable  14  into the socket of a cigarette lighter installed in the vehicle. The air compressor of the compressor unit  12  here is capable of generating compressed air at a pressure higher than the stipulated pressure for each of various types of tire  100  to be repaired (see  FIG. 2 ) (for example at 300 kPa or above). 
     The compressor unit  12  is provided with a power switch  13  and a pressure gauge  16 , with the power switch  13  and the pressure gauge  16  disposed in the vicinity of a central portion of a top face  11 U of the casing  11 . An operation manual  17  explaining the operation sequence is also disposed on the top face  11 U of the casing  11 , to the right hand side of the power switch  13 . 
     As shown in  FIG. 3 , the sealing and pumping device  10  is provided with the liquid agent container  18  containing a sealing agent  32  and with the injection unit  20  connected to the liquid agent container  18 . A neck portion  26  is integrally formed to a portion at the bottom end of the liquid agent container  18 , the neck portion  26  being substantially a circular cylinder shape projecting downwards. The neck portion  26  is formed with a diameter narrower than that of a body portion of the container above the neck portion  26 . An aluminum seal  30  is disposed across the open end of the neck portion  26 , in order to seal the sealing agent  32  within the liquid agent container  18 . The outer peripheral edge portion of the aluminum seal  30  is fixed around the whole of the peripheral edge portion of the opening of the neck portion  26 , by use of an adhesive or the like, A step portion  28  is formed at an intermediate portion of the neck portion  26 , projecting toward the peripheral outside. 
     The liquid agent container  18  is formed from a material with gas blocking characteristics, such as various resin materials or metal materials such as aluminum alloys or the like. Slightly more sealing agent  32  is filled within the liquid agent container  18  than the standard amount (for example 200 g to 400 g) corresponding to the each type and size etc. of the tire  100  requiring repair by the sealing and pumping device  10 . It should be noted that the liquid agent container  18  of the present exemplary embodiment is filled with the sealing agent  32  with no voids therein and without provision of an air space, however a small amount of an inert gas such as Ar or the like may be sealed together with the sealing agent  32  within the liquid agent container  18  when filling, in order to prevent alternation of the sealing agent  32  by oxidation etc. 
     When the sealing and pumping device  10  is in a state in which the liquid agent container  18  is positioned directly above the injection unit  20 , the aluminum seal  30  of the liquid agent container  18  is in a pressure applied state due to the weight of the sealing agent  32  itself within the liquid agent container  18 . 
     A unit main body portion  34  and a foot portion  36  are integrally provided in the injection unit  20 , as shown in  FIG. 3 . The unit main body portion  34  is formed in a substantially circular bottomed cylinder shape, open toward the top, and the foot portion  36  is of a circular flange shape extending to the outer peripheral side from a portion at the bottom of the unit main body portion  34 . The neck portion  26  is welded to the unit main body portion  34 , by a method such as by inserting the bottom end of the neck portion  26  of the liquid agent container  18  into the unit main body portion  34 , and spin welding the top face of the unit main body portion  34  to the step portion  28  of the neck portion  26 . 
     A substantially circular column shaped liquid supply pressure chamber  40  is provided within the unit main body portion  34 , when the aluminum seal  30  is ruptured the liquid supply pressure chamber  40  is in communication with the inside of the liquid agent container  18 . A circular cylinder shaped inner peripheral tubular portion  42  is formed coaxially to the injection unit  20  at the peripheral inside of the unit main body portion  34 . A jig insertion hole  44  is formed with a circular cross-section at a central portion of the inner peripheral tubular portion  42 , passing through from the bottom end face of the injection unit  20  to the top end face of the inner peripheral tubular portion  42 . An insertion fitting recess portion  46  is formed as a circular shaped recess to a central portion of the bottom end face of the injection unit  20 , with the internal diameter of the insertion fitting recess portion  46  being larger than the internal diameter of the jig insertion hole  44 . The bottom end of the jig insertion hole  44  thereby opens to the bottom face central portion of the insertion fitting recess portion  46 . 
     As shown in  FIG. 3 , an insertion guide face  48  is formed in a tapered shape to the inner peripheral surface of the jig insertion hole  44 , with the internal diameter at the open end portion on the entry side reducing in diameter on progression from the open end further into the opening. The insertion guide face  48  is provided for guiding the leading end portion of a later described press jig  82  toward the far side of the jig insertion hole  44  when the press jig  82  is being inserted into the jig insertion hole  44 . 
     As shown in  FIG. 2 , a high pressure hose  24  is provided to the sealing and pumping device  10 , extending from the compressor unit  12  to the injection unit  20 . A portion at one end of the high pressure hose  24  is connected to the air compressor in the compressor unit  12 . 
     As shown in  FIG. 3 , a circular cylindrical shaped air supply tube  52  is formed in the injection unit  20  extending from the outer peripheral face of the inner peripheral tubular portion  42  and passing through the unit main body portion  34  toward the outer peripheral side. The leading end portion at the outer peripheral side of the air supply tube  52  is connected to the leading end of the high pressure hose  24  through a nipple  54 . 
     As shown in  FIG. 3 , plural restricted portions  56  (two in the present exemplary embodiment) are provided at the base end portion of the air supply tube  52 , piercing through the peripheral wall portion of the inner peripheral tubular portion  42  and communicating with the inside of the jig insertion hole  44 . 
     The restricted portions  56  of the inner peripheral tubular portion  42  are formed as through holes each of circular cross-sectional shape, with a uniform internal diameter along the whole of their length, the internal diameter thereof being smaller than the internal diameter of the air supply tube  52 . The inner peripheral ends of the restricted portions  56  are open at an intermediate portion of the inner peripheral face of the inner peripheral tubular portion  42 , and form air supply apertures of circular shape in the inner peripheral face of the inner peripheral tubular portion  42 . 
     The internal space within the high pressure hose  24 , the air supply tube  52  and the restricted portions  56  configures an air supply path  60  for supplying compressed air from the air compressor to the liquid agent container  18  or to the tire  100 . 
     An axial portion  63  of a boring member  62  is inserted into the jig insertion hole  44  at the liquid supply pressure chamber  40  side. A circular flange shaped hole piercing portion  64  is provided spreading out radially toward the outside at a portion at the top end of the axial portion  63 . Blade portions  66  are formed at the outer peripheral edge of the top face of the hole piercing portion  64 , the blade portions  66  formed as protrusion shapes for readily rupturing the aluminum seal  30 , Annular shaped fitting insertion grooves are formed to the outer peripheral surface of the axial portion  63 , at positions above and below the air supply ports  58  when the axial portion  63  is in an inserted-state within the jig insertion hole  44 . Rubber O-rings  72  are fitted into the fitting insertion grooves. 
     When the axial portion  63  is in the inserted-state into the jig insertion hole  44 , the outer peripheral edge portions of each of the pair of O-rings  72  are in contact and pressed by the inner peripheral surface of the jig insertion hole  44  along their entire circumference. The jig insertion hole  44  is thereby in a closely sealed state, with above and below the air supply ports  58  respectively closed off by the axial portion  63  and the pair of O-rings  72 . In this state the axial portion  63  is retained within the jig insertion hole  44  by friction between the O-rings  72  and the inner peripheral surface of the jig insertion hole  44 . In this state the leading end face of the hole piercing portion  64  directly faces the center of the aluminum seal  30 , with there being a small gap present between the hole piercing portion  64  and the aluminum seal  30 . 
     A circular cylindrical shaped air-liquid supply tube  74  is integrally formed in the injection unit  20  so as to penetrate through the peripheral wall of the unit main body portion  34 , as shown in  FIG. 3 . The base end portion of a joint hose  78  is connected through a nipple  76  to the leading end portion at the outer peripheral side of the air-liquid supply tube  74 . A valve adapter  80 , detachably connecting to a tire valve  102  of the tire  100 , is provided at the leading end portion of the joint hose  78 . The base end side of the air-liquid supply tube  74  is inserted into the liquid supply pressure chamber  40 . The joint hose  78  is thereby in communication with the inside of the liquid supply pressure chamber  40  through the air-liquid supply tube  74 . 
     The press jig  82 , as shown in  FIG. 3 , is provided with a bar shaped insertion portion  84  and a circular flange shaped base portion  86  formed to one end of the insertion portion  84 . A jig communication path  88  is formed in the insertion portion  84 , the jig communication path  88  extending from the leading end face toward the base portion  86  side, branching at an intermediate portion into plural branches (for example 2 branches), with each branch extending out toward the outer peripheral side. An annular shaped communication groove  90  is formed in the outer peripheral surface of the insertion portion  84 , forming an airway to the opening portions of the jig communication path  88 . 
     A pair of fitting insertion grooves are formed respectively above and below the communication groove  90  in the outer peripheral surface of the insertion portion  84 . O-rings  96  are respectively fitted into the pair of fitting insertion grooves. The O-rings  96  used are of the same dimension and material as of the O-rings  72  disposed in the boring member  62 . 
     A fitting insertion projection portion  98  is integrally formed to the press jig  82 , between the base end portion of the insertion portion  84  and the base portion  86 , with a diameter larger than that of the insertion portion  84 . The fitting insertion projection portion  98  has an external diameter and height corresponding to the internal diameter and depth of the insertion fitting recess portion  46  formed in the bottom end face of the injection unit  20 . Thereby, as shown in  FIG. 4 , the fitting insertion projection portion  98  fits inserted within the insertion fitting recess portion  46  when the whole of the insertion portion  84  is inserted within the jig insertion hole  44 . In this state the press jig  82  is retained by friction, with the insertion portion  84  in an inserted state within the jig insertion hole  44 , by the fitting insertion projection portion  98  being in a press-fit state, insertion fitted within the insertion fitting recess portion  46 . 
     The length of the insertion portion  84  is slightly longer than the dimension from the bottom end of the jig insertion hole  44  up to the aluminum seat  30 . Thereby, when the entire insertion portion  84  of the press jig  82  is inserted within the jig insertion hole  44 , as shown in  FIG. 4 , the boring member  62  is securely pushed out from inside of the jig insertion hole  44 , and the upper end portion of the press jig  82  is inserted into the liquid agent container  18 . In the state in which the entire insertion portion  84  is inserted into the jig insertion hole  44 , the communication groove  90  of the insertion portion  84  and the air supply ports  58  are aligned with each other along the axial direction. The air supply path  60  is thereby in communication with the jig communication path  88  of the press jig  82  through the communication groove  90 . 
     The outer peripheral edge portions of each of the pair of O-rings  96  are pressed along the entire circumferential direction by the inner peripheral surface of the jig insertion hole  44  when the insertion portion  84  is in the inserted state within the jig insertion hole  44 . The jig insertion hole  44  is thereby in a closely sealed state with both above and below the air supply ports  58  closed off by the insertion portion  84  and the pair of O-rings  96 . 
     As shown in  FIG. 1 , a groove  25  is formed in a front wall face  11 F of the casing  11 , for storing the joint hose  78  and the valve adapter  80 . The joint hose  78  and the valve adapter  80  are usually fitted into and stored in the groove  25 . A jig storage hole  19  is formed in the front wall face  11 F for attaching the press jig  82 , and the insertion portion  84  of the press jig  82  is usually stored in the jig storage hole  19 . 
     As shown in  FIG. 5B , a storage recess  122  is formed in a bottom face  11 B of the casing  11  for storing the power source cable  14  and the plug  15 , and the power source cable  14  and the plug  15  are usually stored within the storage recess  122 . A through hole  108  is provided in the bottom face  11 B, connecting to the insertion fitting recess portion  46  of the injection unit  20 . The diameter of the through hole  108  is larger than the external diameter of the base portion  86  of the press jig  82 , as shown in  FIG. 3  and  FIG. 4 . In the present exemplary embodiment the thickness of the bottom face  11 B of the casing  11  is set thicker than the thickness of the base portion  86 . The through hole  108  is normally closed off by a non-illustrated closure, and the closure is removed from the through hole  108  when the press jig  82  is inserted into the jig insertion hole  44 . 
     As shown in  FIG. 5A , a pair of lids  124  are provided in the casing  11  so as to cover the storage recess  122 . The cross-sections of the lids  124  are substantially L-shaped, with outer faces  124 A in one direction level with the wall face of the casing  11  or positioned further inside than the wall face, and the other outer faces  124 B in the other direction level with the bottom face  11 B of the casing  11  or positioned further inside than the bottom face  11 B, with the end faces  126  in the other direction meeting each other. Shaft portions  125  are provided protruding in circular column shapes from both side faces  128  at the one direction side of the lids  124 . The shaft portions  125  engage with non-illustrated shaft receiving portions provided to the casing  11 , such that the rotational axes of the lids  124  are along the arrow Y direction. The lids  124  are thereby rotatably supported by the casing  11  (see  FIG. 6  and  FIG. 7 ). 
     The lids  124 , as shown in  FIG. 5B  and  FIG. 7 , project out toward the outside (in the direction of arrow X here) of the casing  11  by being rotated about the shaft portions  125  as rotation axes (namely, by opening the lids  124 ). When the lids  124  are rotated until the end faces  126  in the other direction of the lids  124  are substantially level with the bottom face  11 B, step portions  129  extending in the arrow Y direction that are provided to the outer face  124 A at the one direction side of the lids  124 , engage with the wall face of the casing  11 , preventing the lids  124  from being opened beyond this point. 
     When the lids  124  are in the above described state in which the end faces  126  in the other direction meet each other, namely when the lids  124  are in a closed state, the lids  124  cover the storage recess  122  without projecting outside of the casing  11 . When the lids  124  are in the state in which the step portions  129  are engaged with the wall face of the casing  11 , the lids  124  project out to the outside from the casing  11  and the end faces  126  in the other direction are substantially level with a bottom face  126 B. 
     Operation of Sealing and Pumping Device 
     Explanation will now be given of the operational sequence when using the sealing and pumping device  10  of the present exemplary embodiment to repair a punctured tire  100 . Explanation (in text and illustrations) of the following sequence (1) to (8) is given in the above mentioned operation manual  17 . 
     (1) When a puncture occurs in the tire  100 , an operator first removes the closure that is closing off the through hole  108 , inserts the insertion portion  84  of the press jig  82  into the jig insertion hole  44  of the sealing and pumping device  10 , and when the base portion  86  of the press jig  82  contacts the foot portion  36  of the injection unit  20 , the fitting insertion projection portion  98  of the press jig  82  is pressed inside the insertion fitting recess portion  46  of the injection unit  20 . The hole piercing portion  64  of the boring member  62 , which is being pressed by the insertion portion  84 , ruptures the aluminum seal  30  and is pressed inside the container, with the insertion portion  84  progressing into the container. 
     The press jig  82  is moved further into the jig insertion hole  44  from the entrance side thereof, while the pair of O-rings  96  disposed at the outer peripheral face of the insertion portion  84  press against the inner peripheral face of the jig insertion hole  44 . Part way through this movement the O-ring  96  disposed at the top of the insertion portion  84  is made to pass to the inner peripheral side of the air supply ports  58 . The boring member  62  is also moved so that the axial portion  63  moves from inside the jig insertion hole  44  to the exit end side thereof, while the pair of O-rings  96  disposed on the outer peripheral face of the axial portion  63  press against the inner peripheral face of the jig insertion hole  44 . Part way through this movement the O-ring  72  disposed at the bottom of the axial portion  63  is made to pass to the inner peripheral side of the air supply ports  58 . 
     (2) Next, the lids  124  on both sides of the casing  11  are opened, and the sealing and pumping device  10  is placed, for example, on a road surface so that the foot portion  36  is at the bottom and the liquid agent container  18  is at the top (the upright state, see  FIG. 1  to  FIG. 3 ). The power source cable  14  stored in the storage recess  122  is pulled out at this stage. 
     When the insertion portion  84  of the press jig  82  has been inserted within the jig insertion hole  44  of the injection unit  20 , as shown in  FIG. 4 , the leading end of the insertion portion  84  projects out from the leading end of the inner peripheral tubular portion  42 , and faces a hole  31  opened in the aluminum seal  30  by the boring member  62 . The sealing agent  32  in the liquid agent container  18  flows out into the liquid supply pressure chamber  40  through the hole  31 . 
     (3) Next, the joint hose  78  is pulled out from the groove  25 , and the valve adapter  80  of the joint hose  78  is connected to the tire valve  102  of the tire  100  (see  FIG. 2 ), communicating the liquid supply pressure chamber  40  with the inside of the tire  100  through the joint hose  78 . 
     (4) The plug  15  is inserted into a socket, such as a socket of a cigarette lighter installed in a vehicle. 
     (5) The engine of the vehicle is turned on. 
     (6) The power switch  13  is switched on, and the compressor unit  12  is actuated. The compressed air generated by the compressor unit  12  is supplied into the liquid agent container  18  through the high pressure hose  24 , the air supply path  60 , and the jig communication path  88  (see  FIG. 4 ). 
     When compressed air is fed into the liquid agent container  18 , the compressed air rises to the top of the sealing agent  32  within the liquid agent container  18 , and a space (air layer) is formed in the liquid agent container  18  above the sealing agent  32 . The sealing agent  32 , pushed by the compressed air from the air layer, is fed into the liquid supply pressure chamber  40  through the hole  31  opened in the aluminum seal  30 , and injected from within the liquid supply pressure chamber  40  into the pneumatic tire  100  through the joint hose  78 . 
     Note that after all of the sealing agent  32  in the liquid agent container  18  has been expelled, the sealing agent  32  in the liquid supply pressure chamber  40  is pressurized and pushed through the joint hose  78  and fed into the pneumatic tire  100 . Then when all of the sealing agent  32  has been ejected from the liquid supply pressure chamber  40  and the joint hose  78 , compressed air is injected into the tire  100  through the liquid supply pressure chamber  40  and the joint hose  78 . 
     Next, when an operator has confirmed with the pressure gauge  16  that the internal pressure of the tire  100  is the stipulated pressure, then the power switch  13  is switched off and the compressor unit  12  halted, and the valve adapter  80  is removed from the tire valve  102 . 
     Within a specific period of time after finishing inflating the tire  100  the operator performs preparatory running of the tire by traveling a specific distance (for example 10 km) using the sealing agent  32  injected tire  100 . The sealing agent  32  within the tire  100  thereby spreads out uniformly, the sealing agent  32  fills the puncture hole and seals the puncture hole. 
     (8) After completing preparatory running, the operator connects the valve adapter  80  of the joint hose  78  to the tire valve  102  of the tire  100 , as shown in  FIG. 2 , and re-measures the internal pressure of the tire  100  using the pressure gauge  16 . If the stipulated pressure is not met, then the compressor unit  12  is re-actuated and the tire  100  is pressurized to the stipulated internal pressure. Puncture repair of the tire  100  is thereby completed and it is possible to drive using the tire  100  within a specific distance range while not exceeding a specific speed (for example not exceeding 80 km/h). 
     In the sealing and pumping device  10  of the present exemplary embodiment, the lids  124  project out from both outside edges of the casing  11  by rotating the lids  124 , and by placing the casing  11  on the road surface in this state, the end faces  126  in the other direction of the lids  124  contact the road surface. The shape of contact with the ground of the casing  11  is then larger than prior to projecting out the lids  124 . More precisely the ground contact shape is widened in the arrow X direction, in the width direction of the casing  11 . For example, if a casing is placed on a surface supported at 3 points, then the casing becomes more difficult to tip over in a given direction, the greater the separation distance in this direction between imaginary lines connecting these 3 points and a vertical line down from the center of gravity of the casing. The sense of stability of the casing  11  is increased and tipping over is suppressed due to the ground contact shape in the arrow X direction being widened by the lids  124  in the thin casing  11 . The double-dot broken lines  123 L in  FIG. 5B  represent imaginary lines connecting between the support points of the casing  11 . 
     By closing the lids  124 , the lids  124  are made so as not to project outside from the casing  11 , so there is no concern of detriment to the space saving characteristics of the casing  11  due to the lid  124 , and storage space within a vehicle can be effectively utilized by, for example, storing the casing  11  in this state in the vehicle. Consequently, the sealing and pumping device  10  can suppress tipping over while also maintaining space saving characteristics. 
     Since the lids  124  are utilized both as lids of the storage recess  122  of the casing  11  for storing the power source cable  14 , and as tipping suppression members for suppressing tipping over of the casing  11 , the number of components of the sealing and pumping device  10  is reduced, and a reduction in cost is achieved. 
     In addition, since the lids  124  are rotatably supported on the casing  11 , there is no concern of the lids  124  being lost or the like. 
     In the present exemplary embodiment, the pair of lids  124  are rotatably supported on the casing  11  by engagement of the shaft portions  125  with shaft receiving portions, however there is no limitation so such a configuration, and any method of engagement may be utilized as long as the lids  124  are rotatably supported on casing  11 . For example, a hinge or the like may be employed for rotatably supporting the lids  124  on the casing  11 . There may also be a single lid  124  or plural lids  124 , depending on the shape of the casing  11 . 
     Furthermore, in the present exemplary embodiment, the joint hose  78  is stored within the groove  25 , however, for example, configuration may be made in which the joint hose  78  is stored in the storage recess  122 , and when using the sealing and pumping device  10 , the lids  124  on both sides are opened and the joint hose  78  is pulled out together with the power source cable  14 . 
     Second Exemplary Embodiment 
     Explanation will now be given of a second exemplary embodiment of a sealing and pumping device of the present invention, with reference to  FIG. 8  and  FIG. 10 . Since the sealing and pumping device  130  of the second exemplary embodiment differs from the sealing and pumping device  10  of the first exemplary embodiment from the standpoint of the tipping over suppressing structure, only the tipping over suppressing structure will be explained below. Similar parts of the configuration to those of the first exemplary embodiment, are allocated the same reference numerals and explanation thereof is omitted. 
     As shown in  FIG. 8A , a pair of lids  134  is provided covering a storage recess  122  in a casing  131 . The lids  134  are of a plate shape, and one end face thereof, at the outside in the arrow X direction, is level with the wall face of the casing  131  or is positioned further inside than this wall face, a bottom face  134 B thereof, at the bottom in the arrow Z direction, is level with a bottom face  131 B of the casing  131 , and the other end faces  136  at the inside in the arrow X direction meet each other. Substantially circular column shaped shafts  135  are provided at the corner portions formed at the outside in the arrow X direction of the top face, at the top side in the arrow Z direction, of the lids  134  and at the center side in the arrow Y direction, the shafts  135  projecting upward from the top face. The shafts  135  engage with shaft receiving portions  137  provided on the casing  131 , such that rotational axes of the lids  134  are along the arrow Z direction. The lids  134  are thereby rotatably supported on the casing  131  (see  FIG. 9  and  FIG. 10 ). 
     As shown in  FIG. 8B  and  FIG. 10 , the lids  134  are made to project outside (the arrow X direction in this case) from the casing  131  by rotating the lids  134  about the rotational axes of the shafts  135  (namely, by opening the lids  134 ). When the lids  134  are rotated until the other end faces  136  of the lids  134  are positioned substantially orthogonal to the arrow Y direction, the lids  134  are prevented from rotating by non-illustrated stoppers so as not to open any further. 
     Explanation will now be given of the operation of the second exemplary embodiment. In the sealing and pumping device  130  of the present exemplary embodiment, the lids  134  are made to project out to the outside on both sides of the casing  131  by rotating the lids  134  and opening out to both sides. The bottom faces  134 B of the lids  134  have ground contact with the road surface by placing the casing  131  on the road surface in this state. The ground contact shape of the casing  131  becomes larger at this time than prior to projecting the lids  134  out. More precisely the ground contact shape in the arrow X direction is wider. The sense of stability of the casing  131  is increased and tipping over is suppressed. Note that the double-dot broken lines  133 L in  FIG. 8B  show imaginary lines connecting between the support points of the casing  131 . 
     Since by closing the lids  134  the lids  134  are made so as not to project out to the outside from the casing  131 , there is also no concern of detriment to the space saving characteristics of the casing  131  due to the lids  134 , and storage space within a vehicle can be effectively utilized by, for example, storing the casing  131  in this state in the vehicle. Consequently, the sealing and pumping device  130  can suppress tipping over while also maintaining space saving characteristics. Since the lids  134  are utilized both as lids of the storage recess  122  of the casing  131  for storing the power source cable  14 , and as tipping suppression members for suppressing tipping over of the casing  131 , the number of components of the sealing and pumping device  130  is reduced, and a reduction in cost is achieved. In addition, since the lids  134  are rotatably supported on the casing  131 , there is no concern of the lids  134  being lost or the like. 
     Third Exemplary Embodiment 
     Explanation will now be given of a third exemplary embodiment of a sealing and pumping device of the present invention, with reference to  FIG. 11  and  FIG. 12 . Since the sealing and pumping device  140  of the third exemplary embodiment differs from the sealing and pumping device  10  of the first exemplary embodiment from the standpoint of the tipping over suppressing structure, only the tipping over suppressing structure will be explained below. Similar parts of the configuration to those of the first exemplary embodiment, are allocated the same reference numerals and explanation thereof is omitted. 
     As shown in  FIG. 11A , a pair of lids  144  is provided covering a storage recess  122  in a casing  141 . The lids  144  are of a plate shape, and one end face thereof at the outside in the arrow X direction is level with the wall face of the casing  141  or is positioned further inside than this wall face, a bottom face  144 B thereof at the bottom in the arrow Z direction is level with a bottom face  141 B of the casing  141 , and the other end faces  146  thereof at the inside in the arrow X direction meet each other. Slide receiving portions  145  are provided at portions at both sides in the arrow Y direction of a top face at the top side of the lid  144  in the arrow Z direction, with the slide receiving portions  145  projecting upward in the arrow Z direction from the top face. The slide receiving portions  145  are engaged with slide rails  147  provided below the casing  141 , such that the sliding direction of the lids  144  is along the arrow X direction. The lids  144  are thereby slidably supported on the casing  141  (see  FIG. 12 ). 
     The lids  144  are made to project outside (the arrow X direction in this case) from the casing  141  by sliding the lids  144  along the slide rails  147  (namely, by opening the lids  144 ), as shown in  FIG. 11B  and  FIG. 12 . When the lids  144  have been slid a certain amount in the arrow X direction, the lids  144  are prevented from sliding in the arrow X axis direction, so as not to open any further, by non-illustrated stoppers provided so that the slide receiving portions  145  do not come out of the slide rails  147 . 
     Explanation will now be given of the operation of the third exemplary embodiment. In the sealing and pumping device  140  of the present exemplary embodiment, the lids  144  are made to project out to the outside on both sides of the casing  141  by sliding the lids  144  and opening out to both sides. The bottom faces  144 B of the lids  144  have ground contact with the road surface by placing the casing  141  on the road surface in this state. The ground contact shape of the casing  141  becomes larger at this time than prior to projecting the lids  144  out. More precisely the ground contact shape in the arrow X direction is wider. The sense of stability of the casing  141  is therefore increased and tipping over is suppressed. Note that the double-dot broken lines  143 L in  FIG. 11B  show imaginary lines connecting between the support points of the casing  141 . 
     Since by closing the lids  144 , the lids  144  are made so as not to project out to the outside from the casing  141 , there is also no concern of detriment to the space saving characteristics of the casing  141  due to the lids  144 , and storage space within a vehicle can be effectively utilized by, for example, storing the casing  141  in this state in the vehicle. Consequently, the sealing and pumping device  140  can suppress tipping over while also maintaining space saving characteristics. Since the lids  144  are utilized both as lids of the storage recess  122  of the casing  141  for storing the power source cable  14 , and as tipping suppression members for suppressing tipping over of the casing  141 , the number of components of the sealing and pumping device  140  is reduced, and a reduction in cost is achieved. In addition, since the lids  144  are slidably supported on the casing  141 , there is no concern of the lids  144  being lost or the like. 
     Fourth Exemplary Embodiment 
     Explanation will now be given of a fourth exemplary embodiment of a sealing and pumping device of the present invention, with reference to  FIG. 13  and  FIG. 16 . Since the sealing and pumping device  150  of the third exemplary embodiment differs from the sealing and pumping device  10  of the first exemplary embodiment from the standpoint of the tipping over suppressing structure, only the tipping over suppressing structure will be explained below. Similar parts of the configuration to those of the first exemplary embodiment, are allocated the same reference numerals and explanation thereof is omitted. 
     As shown in  FIG. 13A , a lid  154  is provided covering a storage recess  122  in a casing  151 . The lid  154  is of a plate shape, and both end faces at the outside in the arrow X direction are level with the wall faces of the casing  151  or are positioned further inside than these wall faces, a bottom face  154 B at the bottom in the arrow Z direction is level with a bottom face  151 B of the casing  151 . A substantially circular column shaped shaft  155  is provided to the top face that is upward in the arrow Z direction of the lid  154  and towards the center of the top face in the arrow Y direction and the arrow X direction, the shaft  155  projecting upward from the top face. The shaft  155  is engaged with a substantially circular column shaped shaft receiving portion  157  provided below the casing  151 , such that the rotational axis direction of the lid  154  is along the arrow Z direction. The shaft  155  has a projecting portion  155 A projecting in a direction orthogonal to the axial direction of the shaft  155 , and the shaft receiving portion  157  is divided into four sections around its circumference at the top side thereof, with the projecting portion  155 A fitting into the four divided portions  157 A. When the lid  154  is rotated the projecting portion  155 A comes out from one of the divided portions  157 A and moves around to the next divided portion  157 A. The lid  154  is thereby rotatably supported on the casing  151  (see  FIG. 14  to  FIG. 16 ). 
     As shown in  FIG. 13B , the slide receiving portions  154  is made to project outside (the arrow X direction in this case) from the casing  151  by rotating the lid  154  about the shaft  155  as the rotational axis. When this occurs, an end face  156  at another side, the rear side in the arrow X direction of the lid  154 , is prevented by the stopper of the casing  151  from allowing the lid  134  to rotate any further. 
     Explanation will now be given of the operation of the fourth exemplary embodiment. In the sealing and pumping device  150  of the present exemplary embodiment, the lid  154  is made to project out to the outside on both sides of the casing  151  by rotating the lid  154  as shown in  FIG. 13B . The bottom face  154 B of the lid  154  has ground contact with the road surface by placing the casing  151  on the road surface in this state. The ground contact shape of the casing  151  becomes larger at this time than prior to projecting the lid  154  out. More precisely the ground contact shape in the arrow X direction is wider. The sense of stability of the casing  151  is increased and tipping over is suppressed. Note that the double-dot broken lines  153 L in  FIG. 13B  show imaginary lines connecting between the support points of the casing  151 . 
     Since by rotating the lid  154  as shown in  FIG. 13A , the lid  154  is made so as not to project out to the outside from the casing  151 , there is also no concern of detriment to the space saving characteristics of the casing  151  due to the lid  154 , and storage space within a vehicle can be effectively utilized by, for example, storing the casing  151  in this state in the vehicle. Consequently, the sealing and pumping device  150  can suppress tipping over while also maintaining space saving characteristics. Since the lid  154  is utilized both as a lid of the storage recess  122  of the casing  151  for storing the power source cable  14 , and as tipping suppression members for suppressing tipping over of the casing  151 , the number of components of the sealing and pumping device  150  is reduced, and a reduction in cost is achieved. In addition, since the lid  154  is rotatably supported on the casing  151 , there is no concern of the lid  154  being lost or the like. 
     Fifth Exemplary Embodiment 
     Explanation will now be given of a fifth exemplary embodiment of a sealing and pumping device of the present invention, with reference to  FIG. 17A ,  FIG. 17B  and  FIG. 18 . Since the sealing and pumping device  160  of the fifth exemplary embodiment differs from the sealing and pumping device  10  of the first exemplary embodiment from the standpoint of the tipping over suppressing structure, only the tipping over suppressing structure will be explained below. Similar parts of the configuration to those of the first exemplary embodiment, are allocated the same reference numerals and explanation thereof is omitted. 
     As shown in  FIG. 17A , a lid  164  is detachably mounted to a top face  161 U of a casing  161 , covering a power switch  13  and a pressure gauge  16 . The length of the lid  164  is longer in the arrow Y direction than the length in the arrow X direction, and when in a mounted state to the top face  161 U becomes integrated to the casing  161 , and configures a portion of the top face  161 U. An operation manual  17  is provided to a top face  164 U of the lid  164 . A groove portion  166  is provided to a bottom face  161 B of the casing  161 , the groove portion  166  extending along the arrow X direction with a groove width of the groove portion  166  (length in the arrow Y direction) that is set longer than the length in the arrow X direction of the lid  164 , and a depth of the groove portion  166  (length in the arrow Z direction) the same as the thickness of the lid  164 . 
     As shown in  FIG. 17B , the lid  164  is removed from the casing  161  and in a top-bottom inverted state the lid  164  is fitted into the groove portion  166 . When this occurs, a pair of tabs  165 , projecting out in the arrow Z direction from a bottom face  164 E of the lid  164 , engage with a pair of small openings  167 , provided further up in the arrow Z direction than each of the wall faces of the groove portion  166  of the casing  161 , and the casing  161  and the lid  164  are integrated together. 
     In the present exemplary embodiment, the power source cable  14  and the plug  15  are stored in a non-illustrated recessed portion formed in a rear wall face  161 R of the casing  161 . 
     Explanation will now be given of the operation of the fifth exemplary embodiment. In the sealing and pumping device  160  of the present exemplary embodiment, the lid  164  is made to project out to the outside on both sides of the casing  161  by removing the lid  164  from the top face  161 U and fitting the lid  164  into the groove portion  166 . The top face  164 U of the lid  164  has ground contact with the road surface by placing the casing  161  on the road surface in this state. The ground contact shape of the casing  161  becomes larger at this time than prior to mounting the lid  164 . More precisely the ground contact shape in the arrow X direction is wider. The sense of stability of the casing  161  is increased and tipping over is suppressed. Note that the double-dot broken lines  163 L in  FIG. 17B  show imaginary lines connecting between the support points of the casing  161 . 
     By mounting the lid  164  in the top face  161 U, as shown in  FIG. 17A , the lid  164  is made so as not to project out to the outside from the casing  161 , there is therefore no concern of detriment to the space saving characteristics of the casing  161  due to the lid  164 , and storage space within a vehicle can be effectively utilized by, for example, storing the casing  161  in this state in the vehicle. Consequently, the sealing and pumping device  160  can suppress tipping over while also maintaining space saving characteristics. Since the lid  164  is utilized both as a lid for the top face of the casing  161 , and as a tipping suppression member for suppressing tipping over of the casing  161 , the number of components of the sealing and pumping device  160  is reduced, and a reduction in cost is achieved. In addition, since it is necessary to remove the lid  164  from the top face, mis-operation of the present device by a user is prevented because when the lid is removed the user will read the operation manual  17 . 
     Sixth Exemplary Embodiment 
     Explanation will now be given of a sixth exemplary embodiment of a sealing and pumping device of the present invention, with reference to  FIG. 19 . Similar parts of the configuration to those of the first exemplary embodiment, are allocated the same reference numerals and explanation thereof is omitted. The sealing and pumping device  170  of the present exemplary embodiment, as shown in  FIG. 19 , differs from the standpoint that a lid  174  is employed that has been configured by attaching the press jig  82  to the bottom face of the lid  164  detachably mounted to the top face  161 U of the casing  161  used in the fifth exemplary embodiment, in the standpoint that the liquid agent container  18  and the injection unit  20  are disposed in the vicinity of the center of the casing  161 , and in the standpoint that the jig storage hole  19  is configured at the top face side of the casing  171 . 
     Explanation will now be given of the operation of the sixth exemplary embodiment. In the sealing and pumping device  170  of the sixth exemplary embodiment, as well as obtaining similar actions and effects to those in the fifth exemplary embodiment, the sense of stability is raised when inserting the press jig  82  into the jig insertion hole  44 . 
     Seventh Exemplary Embodiment 
     Explanation will now be given of a seventh exemplary embodiment of a sealing and pumping device of the present invention, with reference to  FIG. 20A  and  FIG. 20B . Since the sealing and pumping device  180  of the seventh exemplary embodiment differs from the sealing and pumping device  10  of the first exemplary embodiment from the standpoint of the tipping over suppressing structure, only the tipping over suppressing structure will be explained below. Similar parts of the configuration to those of the first exemplary embodiment, are allocated the same reference numerals and explanation thereof is omitted. 
     As shown in  FIG. 20B , a storage recess  182 F is formed in a front wall face  181 F of a casing  181 , with a groove  225  formed in a bottom face of the storage recess  182 F, and usually the joint hose  78  and the valve adapter  80  are stored in the groove  225 . A lid  184 F of a plate shape is provided to the front wall face  181 F so as to close off the storage recess  182 F, as shown in  FIG. 20A . An outside face  184 FB of the lid  184 F is level with, the front wall face  181 F or positioned further inside than the front wall face  181 F. The lid  184 F has non-illustrated circular column shaped shaft portions projecting out along the arrow Y direction at side faces at the bottom side in the arrow Z direction of the lid  184 F. The shaft portions engage with shaft receiving portions provided so as to face groove walls of the storage recess  182 F of the casing  181 . The lid  184 F is thereby rotatably supported about the shaft portion as the rotational axis. 
     A non-illustrated storage recess  182 R is formed in a rear wall face  181 R of the casing  181 , the storage recess  182 R being of about the same size as the storage recess  182 F, and a power source cable  14  and a plug  15  are usually stored in the storage recess  182 R. A plate shaped lid  1848  is provided to the rear wall face  181 R so as to close of the storage recess  182 R. An outside face  184 RB of the lid  1848  is level with the rear wall face  181 R or is positioned further to the inside than the rear wall face  181 R. The lid  184 R has non-illustrated shaft portions formed in a circular column shape projecting along the arrow Y direction at side faces of the bottom side in the arrow Z direction of the lid  184 R. The shaft portions engage with shaft receiving portions provided so as to face groove walls of the storage recess  1828  of the casing  181 . The lid  184 R is thereby rotatably supported about the shaft portion as the rotational axis. 
     As shown in  FIG. 20B , the lid  184 F and the lid  184 R are made to project outside (in the arrow X direction here) from both sides of the casing  181  by being rotated about their respective shaft portions as the rotational axis (namely, by opening the lids). When the lid  184 F and the lid  184 R are rotated up to a position where the outside face  184 FB of the lid  184 F and the outside face  184 RB of the lid  1848  are substantially level with the bottom face  11 B, the lid  184 F and the lid  184 R are held in this state by non-illustrated stoppers. The lid  184 F and the lid  184 R become rotatable by releasing these stoppers. Note that the rotational structures for rotatably supporting the lid  184 F and the lid  184 R are similar to the rotational structures of the first exemplary embodiment. 
     Explanation will now be given of the operation of the seventh exemplary embodiment. 
     In the sealing and pumping device  180  of the present exemplary embodiment, the lid  184 F and the lid  184 R are made to project outside from the casing  181  by rotating and opening the lid  184 F and the lid  184 R. The outside face  184 FB of the lid  184 F and the outside face  184 RB of the lid  184 R have ground contact with the road surface by placing the casing  181  on the road surface in this state. The ground contact shape of the casing  181  becomes larger at this time than prior to projecting out the lid  184 F and the lid  184 R. More precisely the ground contact shape in the arrow X direction is wider. The sense of stability of the casing  181  is increased and tipping over is suppressed. Note that the double-dot broken lines  183 L in  FIG. 20B  show imaginary lines connecting between the support points of the casing  181 . 
     Since by closing the lid  184 F and the lid  184 R, the lid  184 F and the lid  184 R are made so as not to project out to the outside from the casing  181 , there is also no concern of detriment to the space saving characteristics of the casing  181  due to the lid  184 F and the lid  1848 , and storage space within a vehicle can be effectively utilized by, for example, storing the casing  181  in this state in the vehicle. Consequently, the sealing and pumping device  180  can suppress tipping over while also maintaining space saving characteristics. Since the lid  184 F and the lid  184 R are utilized both as lids for the storage recess  182 F and the storage recess  1828  of the casing  181 , and as tipping suppression members for suppressing tipping over of the casing  181 , the number of components of the sealing and pumping device  180  is reduced, and a reduction in cost is achieved. In addition, since the lid  184 F and the lid  184 R are rotatably supported on the casing  181  there is no concern of the lid  184 F and the lid  184 R being lost or the like. 
     Eighth Exemplary Embodiment 
     Explanation will now be given of an eighth exemplary embodiment of a sealing and pumping device of the present invention, with reference to  FIG. 21 . Since the sealing and pumping device  190  of the eighth exemplary embodiment differs from the sealing and pumping device  10  of the first exemplary embodiment from the standpoint of the tipping over suppressing structure, only the tipping over suppressing structure will be explained below. Similar parts of the configuration to those of the first exemplary embodiment, are allocated the same reference numerals and explanation thereof is omitted. 
     As shown in  FIG. 21A , a pair of lids  194  is provided at a bottom face  191 B of a casing  191 , covering a through hole  108  at the bottom side of an injection unit  20 . The lids  194  are of a plate shape, and one end face at the outside in the arrow X direction is level with the wall face of the casing  191  or is positioned further inside than this wall face, a bottom face  1943  at the bottom in the arrow Z direction is level with a bottom face  141 B of the casing  191 , and the other end faces  196  at the inside in the arrow X direction meet each other. Slide receiving portions  195  are provided at portions at both sides in the arrow Y direction of a top face at the top side of the lid  194  in the arrow Z direction, with the slide receiving portions  195  projecting upward in the arrow Z direction from the top face. 
     The slide receiving portions  195  are engaged with slide rails  197  provided below the casing  191 , such that the sliding direction of the lids  194  is along the arrow X direction. The lids  194  are thereby slidably supported on the casing  191 . 
     As shown in  FIG. 20B , the lids  194  are made to project outside (the arrow X direction in this case) from the casing  191  by sliding the lids  194  along the slide rails  197  (namely, by opening the lids  194 ). When the lids  194  have been slid a certain amount in the arrow X direction, the lids  194  are prevented from sliding in the arrow X axis direction, so as not to open any further, by a non-illustrated stopper provided so that the slide receiving portions  195  do not come off the slide rails  197 . The through hole  108  is appeared by opening the lids  194 . The structure for making the lid  194  slidable is similar to that employed at the slidable structure of the third exemplary embodiment. 
     Explanation will now be given of the operation of the eighth exemplary embodiment. In the sealing and pumping device  190  of the present exemplary embodiment, the lids  194  are made to project out to the outside on both sides of the casing  191  by sliding the lids  194  and opening out to both sides. The bottom faces  194 B of the lids  194  have ground contact with the road surface by placing the casing  191  on the road surface in this state. The ground contact shape of the casing  191  becomes larger at this time than prior to projecting the lids  194  out. More precisely the ground contact shape in the arrow X direction is wider. The sense of stability of the casing  191  is increased and tipping over is suppressed. Note that the double-dot broken lines  193 L in  FIG. 21B  show imaginary lines connecting between the support points of the casing  191 . 
     By closing the lids  194 , the lids  194  are made so as not to project out to the outside from the casing  191 , there is therefore no concern of detriment to the space saving characteristics of the casing  191  due to the lids  194 , and storage space within a vehicle can be effectively utilized by, for example, storing the casing  191  in this state in the vehicle, Consequently, the sealing and pumping device  190  can suppress tipping over while also maintaining space saving characteristics. Since the lids  194  are utilized both as lids covering the through hole  108 , and as tipping suppression members for suppressing tipping over of the casing  191 , the number of components of the sealing and pumping device  190  is reduced, and a reduction in cost is achieved. In addition, since the lids  194  are slidably supported on the casing  191 , there is no concern of the lids  194  being lost or the like. 
     Furthermore, since the through hole  108  is usually covered by the lids  194 , the lids  194  need to be opened in order to insert the press jig  82  into the jig insertion hole  44 . Consequently, when placing the casing  191  on the road surface, placement is made with the lid  194  assuredly in the open state. 
     Also, while in the eighth exemplary embodiment the lids  194  are of a slidable structure, there is no limitation to such a configuration, and for example configuration may be made with a double door structure employed for the lids  194 , as utilized in the first exemplary embodiment. 
     Other Exemplary Embodiments 
     In the first to the fourth and the seventh and eighth exemplary embodiments the member(s) used for tipping over suppressing were each configured so as to be slidably supported or rotationally supported. However there is no limitation to such configurations, and these members may be configured as detachably mounted members.
