Title:
FLUID PRESSURE DEVICE AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2017/064898
Kind Code:
A1
Abstract:
The present invention relates to a fluid pressure cylinder. A first stepped section (24) having a greater diameter than a cylinder chamber (20) is formed at one end (12a) of a cylinder tube (12) constituting a fluid pressure cylinder (10). A disc-shaped head cover (14) is inserted into the cylinder chamber (20). The one end (12a) is pressed and plastically deformed by a staking jig (50) to form a deformed section (28), and the head cover (14) is affixed within the first stepped section (24) by the deformed section (28). As a result of this configuration, the head cover (14) can be more firmly affixed while the sealing effect between the cylinder tube (12) and the head cover (14) is ensured. This eliminates need for a seal means and an engagement means which is used to affix the head cover (14), and consequently, the number of parts can be reduced.
