Abstract
An urging spring (15) urges a friction pad toward the exit side of the rotational direction of a disk when a vehicle equipped with the disk brake runs forward. The urging spring is disposed between a lug portion (11A) of the friction pad and a torque receiving surface (5) of a carrier (2). The distal end of the urging spring is configured to abut against the disk to perform wear detection. The urging spring includes a mounting portion (15A), a first extending portion (15B), a boundary region (15E), a bent portion (15C), and a second extending portion (15D). The boundary region is reduced in width to lower stiffness. The bent portion is increased in width and provided with reinforcing portions, thereby enhancing the stiffness. Thus, the natural frequencies of the second extending portion in the rotational direction K and the vertical direction J come close to each other.
