PROBLEM TO BE SOLVED: To propose a brake pad structure for a disc brake to effectively prevent vibration or the like when braking force is generated. SOLUTION: A support plate spring 40 composed of shape memory alloy is mounted between a brake pad 15 and a mounting 50. The support plate spring 40 holds the brake pad 15 and is held by the mounting 50. At low temperature, the support plate spring 40 firmly holds the brake pad 15 so that the brake pad 15 is comparatively strongly constrained. On the other hand, when the support plate spring 40 reaches a prescribed high temperature area by generation of braking force, the support plate spring 40 is thermally deformed, and holding power to the brake pad 15 is reduced, thus the brake pad 15 is weakly constrained. Thus following capability of the brake pad 15 is improved and brake vibration is reduced at high temperature where difference in thickness of a disc rotor is increased. COPYRIGHT: (C)2006,JPO&NCIPI
