PROBLEM TO BE SOLVED: To provide an antirattler by which no unpleasant noise is made even if an outer cylinder and a shaft are relatively displaced in the axial direction due to vibration and by which riding comfort can be enhanced because the displacement surely acts on an elastic body as a load. SOLUTION: A flange part 18A, which is a projected part for preventing a shaft 18 from coming off, and a letter-C-shaped, concentric retaining ring 24 are prepared, while a belleville spring 24 for generating energizing force in the axial direction is interposed between the projected part for preventing the shaft (18) from coming off and an end surface 16A of an inner cylinder 16. As a result, the shaft 18 and the inner cylinder 16 are constantly tightened with each other as an integrated body owing to the energizing force of the belleville spring 26 in the axial direction, thereby constantly synchronizing the displacement of the inner cylinder 16 and that of the shaft 18. Accordingly, even if a void is produced by friction between the projected part for preventing the shaft (18) from coming off and the end surface 16A of the inner cylinder 16, the belleville spring 26 deforms itself, owing to the energizing force of the belleville spring 26, thereby filling up the void. Therefore, no rattle will be made. |
