<p><P>PROBLEM TO BE SOLVED: To provide a hydraulic pressure cylinder capable of suppressing complication of a piston fastening structure by a cushion mechanism, and setting the deceleration of a piston rod according to the stroke. <P>SOLUTION: The hydraulic pressure cylinder 1 is extended/contracted by the working fluid pressure to be guided from an external working fluid pressure source, and includes a movable sleeve 50 having a sleeve inner circumferential surface to be slidably fitted to a rod outer circumferential surface 31 of a piston rod 30, and a groove-shaped slit 57 to be opened in the sleeve inner circumferential surface. The movable sleeve 50 is abutted on a cylinder head 40 in a vicinity of the stroke end during the extension operation, and the working fluid in a rod chamber 2 is guided to a supply/discharge port 4 through the slit 57 and a rod recess 35. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
