Abstract

A shock absorber has a suspension spring bearing fixed securely to a cylinder. The shock absorber includes a cylinder, a suspension spring bearing on the cylinder, and a suspension spring. A suspension spring bearing includes a cylindrical shaped main body that covers an end of the cylinder, an annular spring bearing part formed on a periphery of the main body, a plurality of upper salients that project inwardly from the main body and that are spaced apart at even intervals around the circumference of the main body, in which the upper salients press against the periphery of the cylinder, and a plurality of lower salients that project inwardly from the main body and that are spaced apart at even intervals around the circumference of the main body at locations below those of the upper salients, in which the lower salients press against the periphery of the cylinder.

Claims

1. A shock absorber comprising:

a cylinder; and

a suspension spring bearing on the cylinder;

wherein said suspension spring bearing is configured to contact the bottom end of a suspension spring, and

wherein said suspension spring bearing comprises;

a cylindrical shaped main body covering an end of said cylinder;

an annular spring bearing part formed on a periphery of said main body;

a plurality of upper salients projecting inwardly from said main body and spaced apart from one another around a circumferential direction of the main body at even intervals, said upper salients bearing against a periphery of said cylinder; and

a plurality of lower salients projecting inwardly from said main body and spaced apart from one another around a circumferential direction of the main body at even intervals, wherein said lower salients are located at a part of said main body that is lower than said upper salients, and wherein said lower salients bear against the periphery of said cylinder.
