An air inlet 19 and a damping liquid inlet / outlet 20 are provided on the side surface of the air tank 10. The air inlet 19 is provided above the liquid surface of the damping liquid 13, that is, so as to communicate with the compressed air,
The damping liquid inlet / outlet 20 is provided at a relatively lower portion of the air tank 10 so as to communicate with the damping liquid 13. Although not shown, a hose is connected to each of them so that the compressed air and the damping liquid can be enclosed and discharged.
