As described above, the pressure accumulating chamber 9 is capable of accumulating compressed air at least twice as high as the air pressure usable by the pneumatic tool. When the air pressure in the accumulating chamber 9 rises above a predetermined pressure, the relief valve 6 activates the compressed air. To the outside, whereby the damage of the air tank 1 can be suppressed. Accordingly, it is possible to easily store compressed air in the accumulator 9 to the maximum extent, and to supply compressed air having a pressure higher than the air pressure that can be stored in the accumulator 9. Can be used without damaging the air tank 1. That is, it is possible to freely select an air compressor to be connected, including an air compressor that supplies compressed air having a pressure higher than the air pressure that can be stored in the pressure accumulating chamber 9.
