Abstract:
A fluid pressure cylinder. A first stepped section having a greater diameter than a cylinder chamber is formed at one end of a cylinder tube constituting a fluid pressure cylinder. A disc-shaped head cover is inserted into the cylinder chamber. The one end is pressed and plastically deformed by a staking jig to form a deformed section, and the head cover is affixed within the first stepped section by the deformed section. As a result of this configuration, the head cover can be more firmly affixed while the sealing effect between the cylinder tube and the head cover is ensured. This eliminates need for a seal means and an engagement means which is used to affix the head cover, and consequently, the number of parts can be reduced.

Claim (Index 8):
A method for producing a fluid pressure device that includes a tubular body having a piston chamber inside, a covering member that is attached to an end of the body, and a piston that is provided in a displaceable manner along the piston chamber, the method comprising the steps of:\n a step of inserting the covering member into an opening at the end of the body and regulating a movement of the covering member toward the piston; and a step of plastically deforming the end so as to bulge into the opening by pressing the end in an axial direction by a jig, and regulating the movement of the covering member toward a side opposite to the piston by a plastically deformed portion.
