設けたことを特徴とする着座検出装置。[Scope of Claim for Utility Model Registration] A pressure regulating valve set to a predetermined detection base pressure, a throttle valve provided downstream of the pressure regulating valve, and a seating reference surface or a detected object downstream of the throttle valve. a detection nozzle that opens on either one of the positioning reference surfaces, and a predetermined setting in which back pressure generated between the detection nozzle and the throttle valve when the object to be detected is seated is one step lower than the detection base pressure. The seating detection device uses a pressure detector to detect when the pressure has reached a pressure, and a pressure accumulation relief valve is provided to maintain the pressure downstream of the throttle valve at a pressure slightly lower than the set pressure of the pressure detector. A seating detection device, characterized in that it is provided near the upstream side of the detection nozzle.
