Claims

[Scope of utility model registration request]

In a disc brake caliper provided with two or more pistons, an arc formed convexly outward with a radius that is concentric with the piston 7 located on the rotation side of the disc rotor 3 and slightly larger than the outer circumferential radius of the piston 7. An outer circumferential edge 12 and an inner circumferential edge 13 formed concentrically with the circumference connecting the centers of each piston are connected to the edge 11 and the arcuate edge 11, and the outer circumferential edge 12
and the end of the inner peripheral edge 13 of the disc rotor 3
A vertical edge 1 passing through the center of the piston 7 located on the rotation side and substantially perpendicular to the outer circumferential edge 12 and the inner circumferential edge 13
A shim 19 made of a thin metal flat plate connected at 7 is provided, and a semicircular through edge 14 that is concentric with each piston 7 and has a diameter slightly smaller than the inner diameter of the piston 7 is provided on the shim 19 to extend the rotation of the disc rotor 3. A cutout edge 15 is formed on the retraction side half of the disc rotor 3 by cutting it slightly larger than the outer peripheral edge of the piston 7, and the arcuate edge 11 is formed on the retraction side half of the disc rotor 3. A caliper for a disc brake, characterized in that it engages with a piston 7 so as to be located at a side end, and the piston 7 presses an inner pad back plate via the shim 19.
