Claims

[Scope of utility model registration request]

゛ If the piston has a cylindrical piston inserted externally into the drive shaft and a cylinder into which the piston is inserted, and a wavy groove in the circumferential direction is provided on either the outer circumferential surface of the piston or the inner circumferential surface of the cylinder, S In a compressor in which a pin that fits into the wavy groove is protruded from the other side, and the piston is reciprocated in the axial direction by rotation of the drive shaft, when the head of the pin is screwed, 1 A compressor characterized in that a tightening tool retaining groove is recessed in the head of the pin.
