レーキ。[Claims for Utility Model Registration] (1) Comprising a disc rotor and a pair of pads each having a back plate and a friction material fixed thereto and facing each other with the disc rotor in between, In a disc brake of a type in which braking is performed by pressing the friction material of the pad against both surfaces of the disc rotor, an annular recess or an annular projection is provided in a portion of the disc rotor that is brought into sliding contact with the friction material,
An annular inclined surface inclined in a direction approaching each other is formed on the outer circumferential side wall surface and the inner circumferential side wall surface of the annular concave portion or the annular convex portion, and on the surface of the friction material facing the disc rotor, the annular inclined surface is formed. It has an outer circumferential side wall surface and an inner circumferential side wall surface of a shape corresponding to the outer circumferential side wall surface and the inner circumferential side wall surface, and is capable of tapered fitting with the annular recess or annular protrusion in a direction parallel to the axis of the disk rotor. A disc brake characterized in that a first arc-shaped convex portion or a first arc-shaped concave portion is provided. (2) A second arcuate recess recessed in the direction of protrusion of the first arcuate convex portion or a recessed direction of the first arcuate recess on a surface of the friction material opposite to the surface facing the disc rotor. A protruding second arc-shaped convex portion is provided, and a second arc-shaped concave portion or a second arc-shaped convex portion of the friction material and the axis of the disc rotor are provided on the side of the back plate to which the friction material is fixed. a third arcuate protrusion or a third arcuate recess that is fixed in a fitted state in a direction parallel to the disc rotor; The braking torque generated in the pad is received by a torque plate fixed to a non-rotating member through a side end surface opposite to the circumferential direction of the disc rotor of a portion of the plate where the third arcuate recess is not provided. The disc brake according to claim 1 of the utility model registration claim, characterized in that:
