Title:

CALIPER BODY FOR VEHICULAR DISC BRAKE

Document Type and Number:

WIPO Patent Application WO/2021/060329

Kind Code:

A1

Abstract:

This caliper body for a vehicular disc brake is capable of obtaining satisfactory braking feel by suppressing the stiffness of the periphery of an intermediate bridge part to be low using a working fluid communication hole, and by satisfactorily keeping the balance of stress exerted on a caliper body during braking. The caliper body 3 comprises a pair of action parts 3a and a bridge part, wherein the action parts 3a each has a plurality of cylinder holes 7 arranged in the disc circumferential direction, and a working fluid communication hole 12 that provides communication between the bottom sections of the adjacent cylinder holes 7. The bridge part has a disc turn-out side bridge part, a disc turn-in side bridge part, and an intermediate bridge part, and a first ceiling opening and a second ceiling opening are provided between the intermediate bridge part and the disc turn-in side bridge part and between the intermediate bridge part and the disc turn-out side bridge part. The working fluid communication hole 12 is formed such that a disc radial center section C1 is offset closer to the outer side in the disc radial direction than the center axis CL1 of each of the cylinder holes 7.
