Claims (3)

A mounting portion attached to a non-rotating portion of the vehicle and having a pair of torque receiving portions spaced apart in the rotational direction of the disc; and a caliper provided slidably on the mounting portion in a state of straddling the outer peripheral side of the disc , A pair of friction pads supported by the torque receiving portions of the mounting portion by ear portions provided at both ends of the back metal and pressed against both side surfaces of the disk, and sliding the ear portions along the torque receiving portions. rotatably to the to guide at a distance from each other in the rotational direction of the disk consists of a pair of the pad spring provided in the mounting portion, the pad spring, the said friction pad attached taken on the torque receiving disc a guide portion for slidably guided in the axial direction of the folded base end portion is returned folded axially inwardly of the axially outer O Ride disk of the disk extending axially outwardly of the disc from the inside the guide It has a part, ahead Parts is formed between each ear portion of the friction pad and the guide portion so as to extend in the axial direction of the disk, and the friction pad in the radial direction biasing unit for biasing the radial direction toward the disk In the disc brake having the above, the radial urging portion is provided with a rib that extends in the axial direction of the disc and has a convex shape toward the friction pad on a sliding surface with the ear portion of the friction pad. Disc brake characterized by. In the disc brake according to claim 1, before cut parts are disc brakes sliding surfaces of the ear portions of the friction pad is characterized that you are formed in an arc shape. A mounting portion attached to a non-rotating portion of the vehicle and having a pair of torque receiving portions spaced apart in the rotational direction of the disc; and a caliper provided slidably on the mounting portion in a state of straddling the outer peripheral side of the disc , A pair of friction pads supported by the torque receiving portions of the mounting portion by ear portions provided at both ends of the back metal and pressed against both side surfaces of the disk, and sliding the ear portions along the torque receiving portions. A pair of pad springs provided on the mounting portion and spaced apart in the rotational direction of the disk to guide the disc in a movable manner. The pad spring is attached to the torque receiving portion and attaches the friction pad to the disc. A guide portion that is slidably guided in the axial direction; a base end portion extending outward in the axial direction of the disc; and a folded portion that is folded back from the axially outer side of the disc toward the axially inner side of the disc. Said plan In the disc brake having a rotation direction biasing portion that is formed so as to extend in the axial direction of the disc between the portion and the friction pad, and biases the friction pad toward the rotation direction of the disc. The disc brake according to claim 1, wherein a rib that extends in the axial direction of the disc and has a convex shape toward the friction pad is provided on the sliding surface with the friction pad .
