Claims

[Claims for Utility Model Registration] A cylindrical inner tube, an outer tube having a larger diameter than the inner tube, and a cylinder chamber formed between the inner tube and the outer tube that is closed at both ends thereof. an outer piston mounted slidably in the axial direction in the cylinder chamber; an inner piston slidably mounted on the inner peripheral surface of the inner tube; and a cylinder cover mounted on the outer piston and the inner piston. Permanent magnets are provided to attract each other; a port for supplying pressurized fluid to the cylinder chamber; a rod connected to the inner piston and passing through at least one of the cylinder covers; The rod is characterized by comprising: an engaging member that is relatively movable in the axial direction and engaged in a rotationally immovable manner; and a rotational drive member that rotationally drives the rod via the engaging member. Composite actuator.
