Abstract: In order to provide durable shock absorbers, a bearing to bear a piston rod is enhanced in wear resistance and made low in friction. A cylindrical-shaped bearing for reciprocatory sliding, to bear a piston rod comprises lengthy inclined portions and a short parallel portion on an inner-peripheral surface of the bearing.

Abstract: In a hydraulic shock-absorber comprising a cylinder, a piston rod provided with a rebound stopper secured thereto, and a rod guide provided at an end of said cylinder which rod guide butts against the rebound stopper at an extension stroke end of the piston rod, the rod guide is formed of a plate and comprises, at the location of butting against the rebound stopper, a butting planar portion extending radially of the cylinder from a lower end of the inner cylindrical portion against which butting planar portion the rebound stopper butts, and a butting slant portion extending downward obliquely toward the cylinder from an outer end of the butting planar portion against which butting slant portion an radially outer portion of the rebound stopper butts, thereby enabling the rod guide to be prevented from being deformed and also allowing the piston rod to always slide smoothly.
