<p>PROBLEM TO BE SOLVED: To secure proper and smooth follow-up performance of a pad to the rocking of a disc by enhancing the degree of freedom of setting a rocking range of the pad, in a disc brake device that is so composed as to always press the pad against the disc in parallel with each other. SOLUTION: This disc brake device is provided with a housing hole 38 formed in a caliper 30 as a support mechanism for the pad 33a (33b) so as to extend in a pressing direction of the pad 33a (33b), and a support member 40 having a part housed in the hole 38. A space (m) for permitting the support member 40 to rock in a predetermined region around a fulcrum P imagined on the pad 33a (33b) side on the same axis as that of the support member 40 is formed between the outer periphery of the support member 40 and the inner periphery of the hole 38. A spherical contact part 39 having a radius R of curvature centering the rocking fulcrum P of the support member 40 is formed between the bottom face of the hole 38 and the rear end of the support member 40.</p> |
