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.
