サーボ機構。[Claims for Utility Model Registration] A cylinder has two pistons, a servo piston and an accumulator piston, and the inside of the cylinder is partitioned by the two pistons to form first to third chambers whose volumes can be changed. The first chamber changes the volume according to the movement of the servo piston, the second chamber changes the volume according to the movement of both the servo piston and the accumulator piston, and the third chamber changes the volume according to the movement of the servo piston. In a servo mechanism that changes a volume according to movement of a humulator piston, and that drives a stem by movement of the servo piston, at least when the stem is driven in a direction to protrude from the cylinder, A servo mechanism characterized by providing communication means for communicating the inside of one chamber with atmospheric pressure.
