Abstract

In order to provide a rotary cylinder or motor having reduced axial dimension and reduced overall size, a distribution shaft 32 is fitted in a fitting bore 13 formed in the center of a piston rod 11, 12. A flange 36 is provided at the rear end of the distribution shaft 32 so as to cover the rear of the cylinder body 1. An annular dog 7 concentric with the rotary axis is integrally formed so as to project outward from the outer periphery of the cylinder body 1. Sensors 50 and 51 for detecting the dog are provided outside the periphery of the flange 36. The sensors 50 and 51 move together with a piston 10 in the direction of the rotary axis while the sensors are prevented from rotation, and the sensors detect the dog 7 to detect the operating position of the piston. Since the dog is formed to project integrally from the outer periphery of the cylinder body, the dog can increase the rigidity of the cylinder body and serves to reduce the overall size of the rotary cylinder.
