The size and weight of can be reduced. Therefore, the degree of freedom in designing the caliper in the wheel is increased, and a design that was impossible in the past at the design stage can be adopted. Further, since the hydraulic pressure supply hole can be formed in a gentle curve or linear shape without having the zigzag shape shown in FIG. 2, the oil flow resistance is small, the hydraulic pressure propagation speed is increased, and the responsiveness of brake operation is increased. Is improved. Furthermore, the machining cost is low because the holes 2a and 2b communicating with the cylinder portions 1A and 1B are only opened in the pipe 2.
