PROBLEM TO BE SOLVED: To provide a technology that makes a retainer hardly deform with respect to a mounting hole in a cap mounted to the mounting hole of a wheel.SOLUTION: The cap 10 mounted to the mounting hole that is formed in the wheel while having a peripheral groove includes: a circular body part 20; a circular support part 22; a peripheral projection part 24 radially projecting from an outer peripheral surface of the body part 20; and a connection shaft. An outermost diameter of the peripheral projection part 24 is equal to or smaller than an inner diameter of the mounting hole. The cap 10 is mounted to the wheel so that the peripheral projection part 24 enters the peripheral groove of the mounting hole.SELECTED DRAWING: Figure 1 |
