装置。 The inside of the cylinder is divided into a working chamber and an atmospheric chamber by a piston fitted therein, and a rod connected to the piston is made to protrude outward from the end wall of the atmospheric chamber so as to be connectable to a driven body, and is connected to the working chamber. In the actuator device, a working fluid supply passage is opened, and a return spring is provided in the atmospheric chamber surrounding the rod and stretched between the piston and the end wall of the cylinder. A cylindrical guide member is provided to guide the
The proximal ends of the axial guide portions separated by the notch are respectively fixed to the piston side and the cylinder end wall side, and the free ends face each other so that the notch and the guide portion can be inserted into and removed from each other. An actuator device comprising two comb-shaped members.
