Claims

[Scope of utility model registration request]

In a disc rotor for a disc brake comprising an annular sliding plate part pressed between a pair of brake pads on the outer periphery of a flange part for attachment to a wheel hub, the sliding plate part is divided into four equal parts in the circumferential direction. Among these parts, the mass and stiffness distribution in the circumferential direction of the two parts facing each other are made uniform, and the mass and stiffness distribution in the circumferential direction of the other pair of parts facing each other is made uniform. 1. A disc rotor for a disc brake, characterized in that the mass and rigidity distributions are uniform, and the masses or rigidities in the two injections are different.
