PROBLEM TO BE SOLVED: To realize a small sized 4-axis output shaft provided within a case by driving it direct with a motor. SOLUTION: This composite type rotary actuator has a structure to obtain a small size 4-shaft rotary actuator by driving an output shafts (13) of four motors provided in a cylindrical case (1) via a reduction device of a planet gear mechanism (100).
