PROBLEM TO BE SOLVED: To provide a caliper body of disk brake for vehicle in which a caliper body molded unit can have versatility and its cost can be reduced.SOLUTION: A disk circumferential central part of a counter disk rotor side surface of an acting part 5a of a caliper body 5 is formed with a union hub part 5h. The first breeder hub part 5j is formed over a union hub part 5h from a disk output side rather from a bottom wall 5i of a cylinder hole 5e at the disk input side and the second breeder hub part 5m is formed over a union hub part 5h from a disk output side rather from a bottom wall of a cylinder hole 5f at the disk output side, respectively. Union hub part 5h, the first breeder hub part and the second breeder hub part 5m are formed by a series of protrusions 5n where the union hub part 5h protrudes outwardly from the first breeder hub part and the second breeder hub part 5m. |
