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).

Description

technical field [0001] The present invention relates to a disc brake device, in particular to a disc brake device. The disc brake device is provided with: a disc rotor connected to a rotating member (such as a hub ) and rotate integrally with the rotating member; a brake caliper, which is connected to a supporting member (such as a vehicle body) so as to straddle a part of the outer circumference of the disc rotor; a pair of brake pads, the pair of brake pads pads arranged to clamp the disc rotor and supported on the caliper in a movable manner in the rotor axial direction through a support shaft; and a piston connected to the caliper for pressing the brake against the disc rotor A pad, the piston adapted to press the back plate of the brake pad such that the pad of the brake pad slidably presses against the braking surface of the disc rotor to brake the disc rotor. Background technique [0002] This type of disc brake apparatus is described, for example, in National Patent...
