Abstract

The present invention is to stabilize behavior of brake pads at the time of braking of a disc brake so as to suppress generation of brake noise, and also to reduce the roll moment of the brake pads generated at the time of braking so as to suppress uneven abrasion of linings. A back plate (41) of a brake pad (40) is biased inward in the rotor radial direction by a plate spring (80). The back plate (41) is engaged at two points with an inner periphery support shaft (61) provided integrally with a caliper (20) on a V-shape inner peripheral abutment (41a) (provided in the back plate (41) on the inner side of a lining (42) in the rotor radial direction and on the center in the rotor circumferential direction), and engaged at one point with an outer periphery support shaft (62) provided integrally with the caliper (20) on an outer peripheral abutment (41b) (provided in the back plate (41) on the outer side of the lining (42) in the rotor radial direction and on the center in the rotor circumferential direction).
