<p>[PROBLEMS] To provide a pressurizing device enabling the mal-function of a switching mechanism and the leakage of a fluid from the seal parts of a pressure absorbing mechanism during the operation to be easily confirmed from the outside, enabling the easy inspection and repair of such defects, and enabling the avoidance of an increase in the size of the device and the lowering of the moving speed of the device in high-speed movement. [MEANS FOR SOLVING PROBLEMS] An axially extending third through-hole is passed through a fixed part from a second fluid chamber to the outside. A shaft body is slidably supported in the thirdthrough-hole so as to close the third through-hole. A valve element is fixed to one end of the shaft body, and an advancing/treating mechanism fixed to an output shaft is connected to the other end. A first communication hole is opened/closed by operating the advancing/treating mechanism to axially advance and retreat the valve element.</p> |
