  The case body 10 has a partition wall 14 extending vertically in the interior thereof, whereby the case body 10 is arranged on one side in the width direction in which the sealing agent container 6 is stored with the cap body 5 facing downward. It is divided into a first box portion 10A having a first storage space 15A and a second box portion 10B having a second storage space 15B on the other side in the width direction in which the compressor 3 is stored. The case body 10 can be divided into a front case portion 10F having the front plate 2d and a rear case portion 10R having a rear plate 2e, and both of them are formed on the side plate 2c on the first housing space 15A side. For example, two to three hook portions 16 (shown in FIG. 2) are provided and fixed by, for example, four to six screw fittings from the rear plate 2e side.

  An opening 10A1 through which the sealing agent container 6 can be taken in and out and a bottom lid 12 that can open and close the opening 10A1 are provided at the bottom of the first box portion 10A. The bottom lid 12 is guided by, for example, a guide groove (not shown) so as to be slidable in the width direction perpendicular to the up / down direction of the sealant container 6, that is, the vertical direction, and in the closed state. The claw-like hook portion 17 (shown in FIG. 4) is easily fixed to the case body 10 in a detachable manner.

  Next, as the compressor 3, various commercially available small-sized compressors that are driven by using an automobile battery as a power source can be used. Since the compressor 3 is heavy, the stability at the time of installation is enhanced by attaching the compressor 3 below the second accommodation space 15B and lowering the center of gravity of the apparatus. Above the compressor 3, a pressure gauge 18 for measuring the pressure of the compressed air generated by the compressor 3 and a power switch 19 of the compressor 3 are mounted side by side so as to be visible or operable from the front side.
