PURPOSE:To attenuate vibration occurring in braking while reducing noise by arranging an elastomer such as leaf spring on the opposite side of a brake pad to the back metal and pressing said elastomer against the back metal side by a fixed means. CONSTITUTION:A brake pad 15 in a disk brake is constituted from a frictional material 17 slidably contacting a rotor and a back metal 22a fixed to said material 17. A leaf spring 21 which is an elastomer concaved to the back metal 22a side before it is mounted is secured fixedly to the back metal 22a by a rivet 23. Thus, when bending vibration is caused by resonance of the brake pad 15 in the braking, relative slippage between the leaf spring 21 and the back metal 22a is caused by the difference of curvature between both members 21, 22a. By the frictional force caused by such slippage between both members 21, 22a is attenuated the vibration of the brake pad 15. |
