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 1):
A fluid pressure device comprising:\n 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, wherein the covering member is inserted into the piston chamber open at the end of the body, and regulated and fixed in an axial direction by a deformed portion formed by deforming the end.
