Abstract:
1. A compound linear motion and rotary actuator: wherein an inside cylinder tube is concentrically provided in an outside cylinder tube and a piston being driven by means of pressurized fluid is fit into a cylindrically shaped cylinder chamber formed between the inside cylinder tube and the outside cylinder tube in a manner so as to be slidable in an axial direction of the piston, and wherein a holder being rotatably supported by means of a bearing in the inside cylinder tube and being caused to be capable of being rotated by means of a rotation drive mechanism is provided, and an output shaft is inserted into the holder, wherein the output shaft slides in the axial direction whereas the output shaft does not rotate relative to the holder, and wherein the output shaft is connected to a rod of the piston in a manner such that the output shaft integrally moves with the rod of the piston in the axial direction whereas the output shaft is rotatable relative to the rod of the piston by means of a bearing.
