(3) The change-over switch 8 is arranged on the upper side of the motor M, with the operation unit 64 exposed on the upper surface of the storage case 2.
(4) The gear reduction means 16 and the compressor main body 22 are arranged vertically between the motor M and the sealing agent container 6 and in the lower part,
(5) The power switch 19 and the pressure gauge 18 are disposed between the changeover switch 8 and the sealing agent container 6 and above the compressor body 22.

  In addition, the relative position between the apparatus structural members in said (1)-(5) means the relative position between the gravity centers of each apparatus structural member. Accordingly, for example, a pressure gauge 18 is allowed to partially overlap the changeover switch 8 in the thickness direction. However, of the apparatus constituent members M, 6, 8, 16, 22, 18, and 19 other than the power switch 19 and the pressure gauge 18 having a relatively small mass, they are arranged without overlapping in the thickness direction. It is more preferable.

  Then, as shown in FIGS. 1 and 2, the center of gravity height Hg of the center of gravity G of the integrated puncture repair device 1 from the lower end of the storage case 2 is 50% or less of the height H0 of the storage case 2. The gravity center distance Lg of the center of gravity G from the lateral width center position CL of the storage case 2 is 10% or less of the lateral width L0 of the storage case 2 and the center of gravity of the center of gravity G from the thickness center position CT of the storage case 2 The distance Tg is regulated to 10% or less of the thickness T0 of the storage case 2. Thereby, the stability of installation can be ensured while forming the device 1 in a compact manner, and the operability and the reliability of operation can be improved by suppressing the overturn.

  In the apparatus 1 of the present embodiment, high-temperature air that is adiabatically compressed is exhausted from the exhaust hole 27c1 of the relief valve 27. When this high-pressure air directly hits the storage case 2, the surface temperature of that portion is increased. High temperatures can cause burns. Accordingly, in this example, the side wall portion of the bottom lid 10 is provided with a heat radiation notch 81 (shown in FIGS. 3 to 5), and the relief valve 27 is supplied with compressed air from the exhaust hole 27c1. A downward exhaust pipe 82 that can discharge toward the notch 81 is provided. From the viewpoint of exhaustability, the notch 81 preferably has a rectangular shape with a height h of 10 to 20 mm and a lateral width w of 20 to 50 mm. In this example, the cut notch 81 passes through the hose 77 dedicated to puncture repair. The notch portion 10A is used as the notch portion 81 for heat dissipation. The exhaust pipe 82 (shown in FIG. 8) is made of heat-resistant rubber and has an inner diameter D of 5 to 10 mm. The heat-resistant rubber is not particularly restricted, but fluorine rubber, silicone rubber, ethylene propylene rubber (EPDM), acrylic rubber, butyl rubber and the like can be suitably employed.

  As mentioned above, although especially preferable embodiment of this invention was explained in full detail, this invention is not limited to embodiment of illustration, It can deform | transform and implement in a various aspect.

  In order to evaluate the stability of road surface installation, an integrated puncture repair apparatus having the internal structure shown in FIGS. 1 to 5 and having the apparatus constituent members attached at the arrangement positions shown in the figure was made as a prototype. The mass of the sealant container (when new) was 578 g, the mass of the compressor was 302 g, the mass of the changeover switch 8 was 33 g, the mass of the pressure gauge was 35 g, and the mass of the power switch 19 was 4 g. The center of gravity height Hg of the center of gravity G of the integrated puncture repair device at that time is 47% of the height H0 of the storage case, and the width center of gravity Lg from the center of the width is 47% of the width L0 of the storage case. The center of gravity distance Tg from the thickness center position was 50% of the thickness T0 of the storage case.

  When this integrated puncture repair device was tilted in the lateral width direction, the fall limit angle θ1 was 30 °, and when it was tilted in the thickness direction, the fall limit angle θ2 was 24 °. It was confirmed that the device could operate stably within the fall limit angles θ1 and θ2. The center-of-gravity height Hg is the highest at the start of injection when the sealant is contained in the sealant container, and the center-of-gravity height Hg decreases as the injection progresses and the remaining amount of sealant decreases. The stability of will increase.
