PROBLEM TO BE SOLVED: To provide a pressure device which can prevent a liquid discharging valve operating member from being operated during the operation, keep the structure comparatively simple, and surely prevent the switching of an open state of a liquid discharging valve from being performed during the operation. SOLUTION: A lid body 5 which can open/close the opening 4a of a pressure chamber 4 in the apparatus main body 2 is connected. The liquid discharging valve 12 which opens/closes piping is attached to a part of the piping for discharging a liquid in the pressure chamber 4 to the outside. The liquid discharging valve operating member 16 is attached to the apparatus main body section being covered by the lid body 5 when the opening 4a of the pressure chamber 4 is closed by the lid body 5 for this pressure device 1.
