摘要： A shock absorber includes a cylinder, a sleeve provided so as to surround the outer circumferential surface of the cylinder, the cylinder formed of a different material from a material for the cylinder, first and second springs provided along the outer circumferential surface of the sleeve, and a slider provided between the first spring and the second spring, and capable of being displaced in an axel direction. The materials for the cylinder and the sleeve are a combination of materials that causes corrosion due to a contact of either one of those with the other one of those. A corrosion inhibitor is provided which suppresses an occurrence of corrosion on the cylinder or on the sleeve. In one embodiment, the materials are metals.
