PROBLEM TO BE SOLVED: To provide a combined actuator, capable of minimizing an actuator by simplifying a structure and reducing a number of pieces of components, reducing the manufacturing cost, and easily controlling the oscillating and linear motions by one fluid pressure driving system. SOLUTION: In a combination actuator combining the oscillating and linear motions of a fluid pressure driving system, an output shaft 24 with a cam groove is coaxially arranged and connected to an output rod 8 of the linear-motion actuator of the fluid pressure which drives through a converting mechanism 20 for converting the linear advancing force into the rotary torque. The output shaft 24 with cam groove comprises a cam groove 30 corresponding to the combining state of the oscillating rotation and the linear motion, and a cam follower 31 fitted in the cam groove 30 for controlling the operation of the output shaft 24 with a cam groove is mounted on a machine body.
