One embodiment of the present invention provides a caliper body including an acting portion having a cylinder bore; a union boss portion having a union hole; and a bleeder boss portion having a bleeder hole. The union boss portion is formed at a central portion of a side surface of the acting portion in a circumferential direction of a disc brake rotor, the side surface being opposite to a side surface facing the disc brake rotor. The bleeder boss portion extends from an outer circumferential side of the bottom wall of the cylinder bore to the union boss portion. The union boss portion and the bleeder boss portion form a continuous projecting portion such that the union boss portion projects further outwards than the bleeder boss portion. |
