Claims

[Claims for Utility Model Registration] 1. A cylinder tube having a fitting groove circumferentially provided on the outer peripheral surface of at least one end;
A split ring whose outer circumferential surface side protrudes from the fitting groove and is fitted into the fitting groove, a cover whose outer circumferential surface is provided with a male threaded portion, and the cylinder tube and the cover are coupled together. A lock nut is provided with a female threaded part screwed into the male threaded part, a guard part, and a pressing part, respectively, on the inner peripheral surface side of the lock nut. Rotation in the tightening direction of the lock nut, in which the split ring fitted in the matching groove is coaxially and loosely inserted almost up to just before the pressing part, and the male threaded part is threaded into the female threaded part. The cylinder device is characterized in that the split ring fitted in the fitting groove is pushed into the pressing portion and tightens one end side of the cylinder tube, thereby fixing the cylinder tube to the cover. 2. A cylinder device characterized in that the fitting grooves are provided around both ends of the cylinder tube, and the cylinder tube includes two of the cover, the lock nut, and the split ring.
