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.

Fluid pressure device and method for manufacturing same

In a pipe joint, a tapered male screw thread is provided at one end and a joint connection section which is connected to a joint section is provided at the other end. The tapered male screw thread has a length adapted so that, when the tapered male screw thread has been fastened to a tapered female screw thread formed in an end cap, the entire length is engaged with the tapered female screw thread, and the sealing effect is obtained by a seal member.

Pipe joint

A pair of penetrating holes are formed along a longitudinal direction in the interior of a cylinder body that constitutes a fluid pressure cylinder. One end of the pair of penetrating holes is sealed by a pair of caps formed in plate-like shapes. The caps, for example, are formed by press molding a plate body made up from a metal material such as aluminum or the like. Outer edge portions of the caps include bent portions, which are inclined at a predetermined angle in a radial outward direction. In addition, the caps are installed by means of the bent portions biting into inner circumferential surfaces of the penetrating holes.
