A bump stopper includes a cap, a stopper configured to receive a bump cushion, and a collar, wherein the cap includes a plate-shaped part having a rod hole into which a piston rod is inserted, and a cylindrical part configured to receive a cylinder, the stopper is provided to the plate-shaped part, and the collar provided to the plate-shaped part opposing the cylinder.

Bump stopper and shock absorber

A rod guide includes a housing portion and a depressed portion formed toward an outer periphery from a starting point located apart from a piston rod by &#xbd; or more of a distance in an axial direction between a bottom surface of the housing portion and a flat portion of an oil seal in a radial direction closest to the piston rod, and a bush is disposed to be flush with the bottom surface or disposed to project.

Shock absorber

A shock absorber includes a damping passage that connects an expanding-side chamber with a contracting-side chamber inside a cylinder, a housing that forms a pressurizing chamber, a free piston that partitions the pressurizing chamber into an expanding-side pressurizing chamber and a contracting-side pressurizing chamber, an expanding-side passage that connects the expanding-side chamber with the expanding-side pressurizing chamber, a contracting-side passage that connects the contracting-side chamber with the contracting-side pressurizing chamber, a spring element configured to suppress displacement of the free piston, a cushion configured to collide with the free piston to suppress displacement of the free piston thereover when the free piston is displaced from the neutral position with respect to the housing by a predetermined displacement amount or more; and a cushion fixing member fixed to the housing, the cushion fixing member holding the cushion.
