A rod guide (6) has a containing section (6a) and a recess (6c) which is formed so as to extend toward the outer peripheral side from a point (6f) which is separated from a piston rod (3) by a distance greater than or equal to half the axial distance between the bottom surface (6b) of the containing section (6a) and the radial flat section (8e) of an oil seal (8), which is located closest to the piston rod 3. A bush (5) is provided so as to be flush with the bottom surface (6b) or so as to protrude further than the bottom surface (6b). |
