Claims

[Scope of utility model registration request]

(1) In the K body pressure cylinder, a concave groove is provided in the circumferential direction of the circumferential surface of the piston rod to form a piston mounting shaft portion with a circular cross section, and the inner circumferential surface is externally fitted into the piston mounting shaft portion, and the side surface is A positioning member that has a locking surface with a larger diameter than the outer diameter of the piston rod and that can be divided into half pieces on a plane that includes the axis is inserted into the groove and abuts against one side of the groove. The above-mentioned stopper member has an inner circumferential surface that fits over the piston mounting shaft portion, a side surface that has a locking surface with a diameter larger than the outer diameter of the piston rod, and is splittable in a plane that includes the shaft center. Fitted into the groove and brought into contact with the other side of the groove,
A groove is provided on the outer peripheral surface of the stopper member, and a retaining ring is fitted into the groove to prevent separation of the stopper member,
The piston body has a shaft hole in the center with a diameter larger than the outside diameter of the piston rod, and it fits between the two stop surfaces mentioned above. a locking portion that fits into the outer peripheral surface of the positioning member and a holding portion that fits onto the outer peripheral surface of the positioning member to prevent separation of the positioning member; A piston mounting device characterized in that a sealing member is attached to the piston mounting device.

(2) The sealing member is a gasket that seals between the piston mounting shaft and the peripheral surface of the shaft hole of the piston body, and two backup rings attached to both sides of the gasket.Request for Utility Model Registration The screwdriver mounting device described in item (1) of the scope.

(3) The piston mounting device according to claim 1 or 2, wherein the piston mounting shaft has a land portion with a large diameter in a portion into which the seal member is inserted. .

(4) The positioning member has a two-stage cylindrical shape having a large diameter portion and a small diameter portion on both sides of the locking surface.Claims (1) to (3) of the Utility Model Registration Claims The piston mounting device according to any one of.

(5) The gap between the outer peripheral surface of the stopper member and the inner peripheral surface of the cylinder tube is one narrower than the radial thickness of the retaining ring, claims (1) to (4)
