Hold the disc 33. When the brake oil is injected from an oil inlet port 115 into the caliper cylinder 1, the piston 2 is moved by the oil pressure. At this time, the first C-shaped retaining ring 21 sequentially pushes the spring 22, the spacer 23, the ball bearing 24, and the second member 25. Here, since the internal thread portion 251 of the second member 25 is engaged with the external thread portion 1041 of the first member 104 and the first member 104 is positioned at the bottom of the first cylindrical cylinder wall 112, the second member The rotation phenomenon occurs at 25, so that the distance between the piston 2 and the bottom of the first cylindrical cylinder wall 112 becomes long, and the rain causes the first brake to cause the piece 31 and the second brake to hold the piece 32. The brake disc 33 is used to generate a braking effect. As described above, in such a brake caliper 100 having an automatic adjustment parking function for the axis of the drive rod 106 and the axis of the piston 2, the number of parts is too complicated and the part processing process is complicated. . Therefore, the overall volume of the brake caliper 100 having the automatic adjustment parking function cannot be effectively reduced, and thus it is disadvantageous for being used in a small space where the space is insufficient.
