Claims

[Claims for Utility Model Registration] (1) The rod body inserted into the cylinder body has a cushion ring on the shaft portion or the mounting spigot formed at the tip, and the above-mentioned shoe is provided on the head portion or bottom portion of the cylinder body. It has a recess that allows the insertion side end of the cushion ring to be inserted, and a narrow annular rib is arranged between the inner periphery of the cushion ring and the outer periphery of the attachment spigot part. A hydraulic cylinder featuring: (2) The annular rib is located at the insertion side end of the cushion ring.
A hydraulic cylinder according to claim 1, wherein the hydraulic cylinder is disposed between the inner periphery of either the central portion or the exposed end and the outer periphery of the fitting spigot portion of the rod body facing thereto. (3) The hydraulic cylinder according to claim 1 or 2, wherein the annular rib is integrally formed on the outer periphery of the mounting spigot part of the rod body to protrude. (4) The hydraulic cylinder according to claim 1 or 2, wherein the annular rib is integrally formed on the inner periphery of the cushion ring to protrude from the inner periphery of the cushion ring. (5) The hydraulic cylinder according to claim 1 or 2, wherein the annular rib is formed in a ring shape that is press-fitted into the outer periphery of the mounting pilot part of the rod body.
