<p>PROBLEM TO BE SOLVED: To facilitate the work such as the assembly or replacement of a protective boot, to sharply improve the work efficiency or maintenance maintenacne. SOLUTION: A sliding pin 11 is constituted of a pin spindle part 12, a calipers fixing part 13, an annular protruding portion 14, and a boot guide part 16, and a fitting groove 15 is formed between the calipers fixing part 13 and the protruding portion 14. The pin spindle part 12 is slidably inserted into the pin insertion hole 3A of the arm part 3 of a mounting bracket 2, to fit the calipers fixing part 13 to the pin fitting part 5D of a pair of calipers 5 via a bolt 6. The fitting parts 7B and 7C of a protective boot 7 are fitted to the fitting groove 3C of the arm part 3 and the fitting groove 15 of the sliding pin 11. When the fitting part 7C of the protective boot 7 is fitted to the fitting groove 15 of the sliding pin 11, the fitting part 7C is diamiter-expanded stepwise toward the protruding portion 14 by the boot guide part 16, to be fitted to the fitting groove 15 so as to cross the protruding portion 14.</p> |
