ABSTRACT:
Since a large part of an outer tube is made of light alloy such as aluminum, plating on a surface of the outer tube sometimes peels off. Thus, the surface of the outer tube is generally painted. However, a problem is presented in the external appearance of the outer tube due to painting. A structure of a front fork includes an outer tube into which an inner tube is movably inserted in an axial direction thereof. A stepped part is formed in the outer tube with a third elastic member fitted to the stepped part. A tube cover includes a lower portion which is supported by the third elastic member. Since an outer surface of the tube cover covering the outer tube is plated, the external appearance can be enhanced. Even if the outer tube has a rough surface, light metal castings or forgings can be used.
