<p>PROBLEM TO BE SOLVED: To improve parts management and assemblage. SOLUTION: Annular grooves 4d are formed to the shaft parts of the ends of male screws 4c of guide pins 4 which are inserted to both supporting arms 5a, 5a of a caliper body 5, and retainers 7 by which ear parts 6a on the disc rotatingly putting-in side of friction pads 6 and ear parts 6b on a disc rotatingly putting-out side are supported so that the friction pad 6 can be moved in the shaft direction of a disc, are integrally formed in such way that retainer parts 7a for supporting the disc rotatingly putting-in side ear parts 6a of the friction pad 6 and retainer parts 7b for supporting the disc rotatingly putting-out side ear parts 6b are connected to each other by a connecting part. Therewith, locking parts 7d having bellying holes in which large diametral holes 7e whose diameters are larger than the diameters of the shaft parts of the guide pins 4 and small diametral holes engaged with the annular grooves 4d of the guide pins 4 are continued, are successively arranged to both retainer parts 7a, 7b. In the retainers 7 under a condition that the caliper body 5 is not assembled to caliper body supporting arms 3, 3, the small diametral holes are engaged with the annular grooves 4d of the guide pins 4 so as to support the friction pads 6 by both retainer parts 7a, 7b.</p> |
