。[Claims for Utility Model Registration] (1) In a fluid pressure actuator in which a displacement body disposed in a fluid pressure action chamber can be reciprocated by fluid pressure, one of the displacement bodies is disposed in the fluid pressure action chamber. A working fluid discharge port is opened at an intermediate position between one travel limit and the other travel limit, and the discharge port can be substantially clogged by the displacement body, and the flow of the working fluid communicated with the discharge port is prevented. A fluid pressure actuator characterized in that a valve means is disposed in the passage. (2) The fluid pressure actuator according to claim (1), wherein the valve means is a valve capable of stopping the flow of the working fluid. (3) The fluid pressure actuator according to claim (1), wherein the valve means is a restriction that reduces the flow area of the working fluid. (4) The fluid pressure actuator according to any one of claims (1) to (3), wherein the fluid pressure action chamber is formed inside the cylinder tube, and the displacement body is a piston. (5) The fluid pressure actuator according to any one of claims (1) to (3), wherein the displacement body is a vane fixed to a shaft and capable of reciprocating rotation.
