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.
