PROBLEM TO BE SOLVED: To guide a displacement member in a stable condition along the direction of the axial line while surely and easily preventing the rattling of the displacement member relative to a cylinder body. SOLUTION: A slider 14 is provided on a cylinder tube 12 at its guide portions 38a, 38b via a guide mechanism 24 displaceably along the direction of the axial line, and a bearing 72 mounted on a first bearing supporting member 86 is always thrust against a guide portion 38a by a first elastic member 152 mounted between the first bearing supporting member 86 of the guide mechanism 24 and one holding portion 70a of the slider 14. Between the other holding portion 70b of the slider 14 and a guide portion 38b, a second bearing supporting member 150 is mounted via a second elastic member 154. A bearing 72 provided on the second bearing supporting member 150 is thrust against the guide portion 38b by the elastic force of the second elastic member 154. COPYRIGHT: (C)2007,JPO&INPIT
