Claims

[Scope of utility model registration request]

A piston is provided on a drive shaft disposed through the cylinder, fluid pressure is supplied to one side of the piston to move the drive shaft in the axial direction, and a compression spring is used to move the drive shaft back to the initial position. In the device, a disk is attached to the outer end of the drive shaft opposite to the driven end, a cylindrical body is provided outside the cylinder, one end of which is fixed to the disk, and a movable side is attached to the other end. A drive device characterized in that a spring receiver is provided, a fixed side spring receiver is provided adjacent to the disk on a base to which the cylinder is attached, and the compression spring is elastically loaded between both the movable and fixed side spring receivers.
