When the hook 83 is inserted into the locking hole 85, the inclined surface of the claw 83B is pushed by the opening of the locking hole 85 and the support 83A is elastically deformed. However, the base 86 of the jig 82 is used as the injection unit. When the claw 83B passes through the locking hole 85 and returns to its original elasticity, the claw 83B is caught by the edge of the locking hole 85, and the jig 82 is removed. To prevent.

As a result, the piercing portion 66 of the piercing member 62 pushed by the jig insertion portion 84 breaks through the aluminum seal 30 and is pushed into the container, and the jig insertion portion 84 enters the container (see FIG. 6).
At this time, the jig 82 presses the jig insertion portion 84 on the inlet side of the jig insertion hole 44 while pressing the pair of O-rings 96 arranged on the outer circumferential surface of the jig insertion portion 84 against the inner circumferential surface of the jig insertion hole 44. The O-ring 96 disposed on the upper side of the jig insertion portion 84 is passed through the inner peripheral side of the air supply port 58 during the movement from the end portion to the back side. Further, the perforating member 62 also presses the pair of O-rings 96 disposed on the outer peripheral surface of the shaft portion 63 against the inner peripheral surface of the jig insertion hole 44, and the end portion of the shaft portion 63 on the outlet side from the jig insertion hole 44. In the middle of the movement, the O-ring 72 disposed on the lower side of the shaft portion 63 is passed through the inner peripheral side of the air supply port 58.

Thereafter, the sealing / pump-up device 10 is placed, for example, on the road surface or the like so that the leg 36 is down and the liquid container 18 is up (upright state; see FIGS. 1, 2 and 4).
When the jig insertion portion 84 of the jig 82 is inserted into the jig insertion hole 44 of the injection unit 20, the distal end portion of the jig insertion portion 84 protrudes from the distal end of the inner peripheral cylindrical portion 42 as shown in FIG. It directly faces the hole 31 opened in the aluminum seal 30 by 62. Further, the sealing agent 32 in the liquid container 18 flows into the pressurized liquid supply chamber 40 through the hole 31.

(2) Next, the black air hose 50 is taken out from the groove 23, and the valve adapter 22 of the air hose 50 is connected to the connection port 21 provided on the upper surface 11U of the casing 11 (see FIG. 4).
(3) Next, the red (RED) joint hose 78 is taken out from the groove 25, the valve adapter 80 of the joint hose 78 is connected to the tire valve 102 of the tire 100 (see FIG. 4), and pressure is applied through the joint hose 78. The liquid supply chamber 40 is communicated with the tire 100.

(4) Insert the plug 15 into a socket such as a cigarette lighter installed in the vehicle.
(5) Start the vehicle engine.
(6) The power switch 13 is turned on to operate the compressor unit 12. The compressed air generated by the compressor unit 12 is supplied into the liquid agent container 18 through the air supply path 60 and the jig communication path 88 (see FIG. 6).
When the compressed air is supplied into the liquid agent container 18, the compressed air floats above the sealing agent 32 in the liquid agent container 18 and forms a space (air layer) on the sealing agent 32 in the liquid agent container 18. The sealing agent 32 pressurized by the air pressure from the air layer is supplied to the pressurized liquid supply chamber 40 through the hole 31 formed in the aluminum seal 30, and passes from the inside of the pressurized liquid supply chamber 40 through the joint hose 78. It is injected into the pneumatic tire 100.

  In addition, after all the sealing agent 32 in the liquid container 18 is discharged, the sealing agent 32 in the pressurized liquid supply chamber 40 is pressurized and supplied into the pneumatic tire 100 through the joint hose 78. Thereafter, when all the sealing agent 32 is discharged from the pressurized liquid supply chamber 40 and the joint hose 78, the compressed air is injected into the tire 100 through the liquid agent container 18, the pressurized liquid supply chamber 40, and the joint hose 78. Is done.

  Next, when the operator confirms that the internal pressure of the tire 100 has become the specified pressure using the pressure gauge 16, the power switch 13 is turned off to stop the compressor unit 12, and the valve adapter 80 is removed from the tire valve 102. Remove.

  The worker travels preliminarily for a certain distance (for example, 10 km) using the tire 100 into which the sealing agent 32 is injected within a certain time after the completion of the inflation of the tire 100. As a result, the sealing agent 32 is uniformly diffused inside the tire 100, and the sealing agent 32 is filled in the puncture hole, thereby closing the puncture hole.

(8) After completion of the preliminary traveling, the operator connects the valve adapter 22 of the air hose 50 to the tire valve 102 of the tire 100 and remeasures the internal pressure of the tire 100 with the pressure gauge 16 as shown in FIG. When the pressure is not reached, the compressor unit 12 is restarted to pressurize the tire 100 to a prescribed internal pressure. Thereby, the puncture repair of the tire 100 is completed, and the tire 100 can be used to travel at a certain speed or less (for example, 80 km / h or less) within a certain distance range.

  In the sealing / pump-up device 10 of the present embodiment, the compressor function and the tire repair can be performed by a simple operation of inserting (pushing) the jig 82 into the jig insertion hole 44 after the lid member 110 is pulled out from the jig insertion hole 44. Since the function can be switched, it is not necessary to change the connection of the hose. Moreover, the complexity of the operation of the jig 82 is improved.

  In the sealing / pump-up device 10 according to the present embodiment, the force in the direction in which the sealing agent 32 and the jig insertion portion 84 of the jig 82 are pulled out from the jig insertion hole 44 when the sealing agent 32 and the compressed air are injected when the tire repair function is used ( Although the pressure x the area of the jig insertion portion 84 acts, the claw 83B of the hook portion 83 provided on the jig 82 is caught on the leg portion 36 of the injection unit 20 as shown in FIG. There is nothing.

  Here, when pressure from compressed air acts on the jig insertion portion 84 inserted into the jig insertion hole 44, the jig insertion portion 84 presses the central portion of the base portion 86, and the base portion 86 supports the claws 83B on both sides. As a result, bending deformation in which the central portion becomes convex occurs. When the base portion 86 undergoes such bending deformation, the column 83A tilts in a direction to press the edge portion of the locking hole 85 on the jig insertion hole side, so that the hooking of the claw 83B to the hole edge portion becomes stronger and preferable. It is a form.

  Further, in the sealing / pump-up device 10, when compressed air is supplied when the compressor function is used, the force in the direction of pulling out from the jig insertion hole 44 to the lid insertion portion 112 of the lid member 110 (pressure × area of the lid insertion portion 112) However, as shown in FIG. 3, the projection 116 provided on the lid member 110 is fitted in the recess 118 on the inner peripheral surface of the jig insertion hole 44, and thus the lid member 110 is prevented from coming out. . When the lid member 110 receives a force in the withdrawal direction, the close contact between the convex portion 116 and the concave portion 118 is strengthened, so that the compressed air is effectively prevented from leaking out from the lid member 110.

  In this embodiment, since the lid member 110 is made of rubber, when the lid insertion portion 112 is inserted into the jig insertion hole 44, the projection 116 is crushed (elastically deformed), and the projection 116 and the depression The convex portion 116 and the concave portion 118 are engaged with each other by being restored at a position where the convex portion 118 is fitted. On the other hand, when pulling out, the lid insertion portion 112 is pulled out from the jig insertion hole 44 in a state where the convex portion 116 is crushed (elastically deformed).
