Abstract
A mounting eye (21) is fastened to a rod by pushing, partially or over an entire periphery, an outer periphery of a joint portion of a mounting eye into an annular groove of the rod. Accordingly, an axial length of a fastening portion can be set shorter than that of a related-art structure (screw fastening), thereby being capable of securing a stroke of the rod of a shock absorber in which the mounting eye is fastened to the rod.
