摘要： A disc brake (10) includes friction pads (24 and 25) that are provided at positions next to a disc rotor (11) in a disc axial direction and provided to be able to move in the disc axial direction, and a carrier (21) that has an inner circumferential surface (21b) supporting the friction pads (24 and 25) and formed along an outer circumferential edge of the disc rotor (11) and filter portions (55 and 56) provided on the inner circumferential surface (21b) in a manner of facing the outer circumferential edge of the disc rotor (11).

摘要： This disk brake includes an attachment member that has support portions movably supporting a pair of brake pads, and a caliper that pressurizes the brake pads against a disk. The attachment member has outer circumferential frame portions, a coupling beam portion, and support main body portions. The outer circumferential frame portions extend in a disk circumferential direction so as to cover the disk while straddling the disk. The coupling beam portion couples the support portions to each other. The support main body portions form the support portions. The outer frame constituting portions constitute the outer frames of the support main body portions. Positions of disk-axially outward side end surfaces in a disk axial direction are the same as positions of the disk-axially outward side end surfaces of the caliper or on sides outward in the disk axial direction.

摘要： This disc brake includes a first friction pad, a second friction pad, a piston, a caliper, a plate member, and an interlock member. The caliper has a cylinder portion, a bridge portion, a claw portion, and a recessed portion. The interlock member has a fixing portion which is fixed to the plate member, a first inward side folded interlock piece which extends in an axial direction of a cylinder hole from the fixing portion and in which a first inward side tip portion folded to an inward side of the cylinder hole in a radial direction abuts a groove, and a first outward side folded interlock piece which extends in the axial direction of the cylinder hole from the fixing portion and in which a first outward side tip portion folded an outward side of the cylinder hole in the radial direction abuts the groove.
