PURPOSE: To separately regulate drive speed in straight movement and oscillation in a combined actuator in which drive control for straight movement and oscillation can be easily conducted at low cost by a single fluid pressure drive system. CONSTITUTION: In a fluid-driven combined actuator in which straight movement and oscillation movement are combined, an output shaft 40 to make desired combined movement by a cam groove 46 and a cam follower 47 in accordance with a connection mode between straight movement and oscillating rotation through converting mechanisms 38, 41 to convert straight movement driving force into rotation torque is disposed on a piston rod 18 regulating rotation of a fluid pressure-driven straight movement cylinder 10 to be concentric to the piston rod 18, so they are continuously provided, where the straight movement cylinder is composed in such a way that piston driving speed is changeable at parts of the straight movement and oscillation rotation by changing fluid supply/discharge passages in accordance with a piston position.
