Abstract:
1. A floating type disc brake, comprising a braking rotor and a hub arranged inside the braking rotor, the braking rotor including an annular rotor portion and a plurality of projections extending radially inward from the inner circumferential portion of the rotor portion, a connecting means for connecting the braking rotor and the hub at positions wherein the projections of the braking rotor are abutted to the outer circumferential portion of the hub, and cutout portions located peripherally on respective sides of each of the projections adjacent a boundary region between the rotor portion and the projections, such that a minimum width between the respective sides of each of the projections, measured at a portion at which the cutout portions are formed, is smaller than a width at a radially inner end of each of the projections, wherein each of the respective sides of the projections includes a convex portion located radially between the radially inner end and each of the cutout portions.
