Claims

[Claims for Utility Model Registration] (1) A main body block provided with a cylinder hole and a guide hole parallel to the cylinder hole, a piston that closely slides within the cylinder hole, and a tip portion connected to the piston. a piston rod protruding from the cylinder hole; a cover forming a fluid pressure chamber in the cylinder hole to drive the piston in at least one direction; and a cover provided on the main body block for supplying pressurized fluid to the fluid pressure chamber. a guide member rotatably mounted within the guide hole; a rotary drive member that rotationally drives the guide member; and a rotary drive member that is slidable in the axial direction and relatively rotated in the circumferential direction by the guide member. an operating shaft that is immovably supported and projects from both ends of the guide hole; a connecting plate that is fixedly connected to the tip of the piston rod and through which one end of the operating shaft slidably passes; and the connecting plate. a stop member provided on the outer periphery of the operating shaft to prevent the connecting plate from coming out of the operating shaft from one end of the operating shaft; A fluid pressure cylinder device comprising: a biasing compression spring. (2) a main body block provided with a guide hole; a cylinder provided integrally with the main body block; a guide member rotatably mounted within the guide hole; and a rotational drive member that rotationally drives the guide member. an operating shaft that is supported by the guide member so as to be slidable in the axial direction and relatively non-rotatable in the circumferential direction and protrudes from both ends of the guide hole; and fixedly connected to the tip of the piston rod of the cylinder. a connecting plate through which one end of the operating shaft is slidably inserted; a stop member for preventing the connecting plate from slipping out of the one end of the operating shaft; and a stop member provided on the outer periphery of the operating shaft. A fluid pressure cylinder device comprising: a compression spring between the operating shaft and the connecting plate that biases the connecting plate in a direction in which the connecting plate comes out from the operating shaft.
