Patent ID: 10161458

Abstract:
To provide a structure for coupling a rotary actuator to a driven body whereby vibration and noise are reduced and assembly, disassembly, and maintenance after attachment to another device are made easy. This structure comprises the following: support parts laid out opposite a frame; a driven body positioned between said support parts; a shaft that holds said driven body and acts as a rotary shaft; and a rotary actuator coupled to said shaft. One end of the shaft is rotatably supported by one of the support parts, and the other end of the shaft is supported by being coupled to the rotary actuator through the opposing frame by being fitted into a tubular recess formed in the output shaft of the rotary actuator. A protrusion that is formed on the rotary actuator and cushioned in the direction of rotation is fitted into an engagement hole in the frame so as to affix the rotary actuator to the frame.
