PROBLEM TO BE SOLVED: To accurately guide a sliding body while maintaining a non-contact state relative to a cylinder tube. SOLUTION: A lower part of a sliding body 4 has a slit 21 over the whole length of a cylinder tube in the axial direction so as to expose a lower surface of the cylinder tube 3. On the other hand, a base member 22 coupled to the lower surface of the cylinder tube 3 through the slit 21 is provided under the cylinder tube 3 in parallel with the cylinder tube 3, and guide mechanisms 28 each guiding the movement of the sliding body 4 are provided between extension parts 25 formed on both sides of the slit 21 of the slide body 4 and right and left side surfaces of a leg 22a of the base member 22.
