Patent ID: 7275625

Claim:
A disk brake pad that controls rotation of a disk rotor by pushing a friction surface of the disk brake pad against the disk rotor while the disk rotor is rotating, the friction surface being the planar surface on which the disk rotor slides, the disk brake pad being formed with respective chamfered portions at an end portion of the disk brake pad at an incoming disk-rotor-rotation side and an end portion of the disk brake pad at an outgoing disk-rotor-rotation side, wherein an edge of an end portion of the friction surface at the incoming disk-rotor-rotation side and an edge of an end portion of the friction surface at the outgoing disk-rotor-rotation side are both formed so that a length of the friction surface in a circumferential direction of the disk rotor decreases toward a center of rotation of the disk rotor, and the edges are formed in a stepped bending shape such that the length of the friction surface in the circumferential direction of the disk rotor decreases from an outer circumference of the friction surface between the edges of the end portions to an inner circumference of the friction surface between the edges of the end portions.
