されている。In this parking brake mechanism, a cam shaft integral with a cam lever which is rotated by pulling a brake cable is inserted into a bearing hole, and a power transmission mechanism such as a sleeve piston or a push rod is inserted into a bottom of a cylinder hole or a communication hole following the same. And the rotational force of the camshaft is converted into thrust by the power transmission mechanism to operate the piston of the hydraulic operating mechanism disposed on the cylinder hole opening side. A bearing such as a needle bearing is interposed in the bearing hole of the caliper body in which the camshaft is accommodated to reduce the rotational resistance of the camshaft. In order to reduce the size, weight, and cost of the body, it has been proposed to use a cylindrical bearing having an inner surface subjected to a low friction treatment.

を損うなどの虞があった。In the press-fitting of the bearing 32, the bearing 32 of the through hole 33a is guided to the bearing hole 31 by rotating the guide table 33 with the stopper pin 35 as a reference. However, since the bearing hole 31 is covered with the guide table 33 and cannot be seen, the bearing 32
It is difficult and time-consuming to align the shaft with the bearing hole 31. Before the bearing 32 is pressed into the bearing hole 31, the tip of the bearing 32 has a tapered hole 31 b.
Since it is set in an unstable state in which only line contact is made, when the tapered hole 31b is squeezed into the bearing hole 31, an unbalanced load acts on the bearing 32, causing a misalignment as shown in FIG. Since the camshaft is press-fitted into the bearing hole 31 while being inclined, the bearing hole 31 and the bearing 32 are damaged or burrs are generated. There is a possibility that smooth rotation may be impaired or durability may be impaired.
