To provide a depressurization mechanism that can reduce an operating force when an operator closes an opening and closing member.SOLUTION: A depressurization mechanism of a pressure device applies pressure to a pressure target body with a pressure body, and the mechanism comprises: an attitude change member 203 that can take a pressurization attitude and a depressurization attitude according to attitude change; a contact member 230 that applies a contact force toward the depressurization attitude to the attitude change member 203 taking the pressurization attitude; and an opening and closing member 81 that can be opened and closed with respect to the pressure device and is installed with the contact member. The contact member 230 is rotatably attached to the opening and closing member 81 and has, between its leading end and base end, an entry part 233 for a leading end of the attitude change member 203.SELECTED DRAWING: Figure 6 【課題】操作者が開閉部材を閉じるときの操作力を小さくできる脱圧機構を提供する。【解決手段】被加圧体に対して加圧体を加圧する加圧装置の脱圧機構において、姿勢変化によって加圧姿勢と脱圧姿勢とを取り得る姿勢変化部材２０３と、加圧姿勢を取る姿勢変化部材２０３に脱圧姿勢に向けての当接力を加える当接部材２３０と、加圧装置に対し開閉可能であり、当接部材が設置された開閉部材８１とを備える。当接部材２３０は、開閉部材８１に回動可能に取り付けられ、先端部と基端部との間に姿勢変化部材２０３の先端の進入部２３３を有する。【選択図】図６
