Claims

[Claims for Utility Model Registration] (1) A diaphragm is disposed within the housing to divide the interior into two chambers, and a rod protruding outward from the housing is disposed on the diaphragm and is biased. An actuator comprising a control means for urging the rod in a protruding direction by a member and controlling the pressure in the chamber to move the rod by a predetermined stroke via the diaphragm. (2) The control means includes a pressure applying member that applies positive pressure or negative pressure to one chamber, and a pressure applying member that operates to release the positive pressure or negative pressure in the chamber when the rod moves a predetermined stroke. The actuator according to claim 1, which has a release member. (3) The pressure release member includes a detection member that detects the movement of the rod and issues a signal when a predetermined stroke has been reached, and a solenoid valve that is activated by the signal from the detection member. The actuator according to the second item in the range.
