When press-fitting into the through-hole 5a of the lever 5, it is necessary to press-fit while holding the outer peripheral surface of the new bearing member 17 parallel to the inner peripheral surface of the through-hole 5a, and this holding is insufficient. Then, it is not possible to apply a uniform pressing force over the entire circumference of the new bearing member 17, which makes accurate press-fitting difficult. In particular, when a thin bearing member made of a brittle metal such as an oil-impregnated sintered alloy is used as the new bearing member 17, the bearing member is distorted unless press fitting is accurately performed, and the new bearing is distorted. When the fulcrum shaft 4 is inserted into the bearing hole 17a of the member 17, the lever 5 cannot be smoothly rotated, which causes trouble during the braking operation of the electromagnetic brake. In order to avoid such inconvenience, the new bearing member 1 for the through hole 5a is formed.
It is sufficient to keep the outer peripheral surface of the new bearing member 17 parallel to the inner peripheral surface of the through hole 5a while measuring the relative position of 7. However, this takes time and labor, and work efficiency is improved. Had lowered.

Since the bearing hole 21a of the existing bearing member 21 is used as a guide portion, the new bearing member 17 can be press-fitted into the through hole 5a of the lever 5, and the existing bearing member 21 can be pressed. Since the new bearing member 17 can be pressed into the through hole 5a at the same time while removing the member 21, the new bearing member 17 can be accurately inserted into the through hole 5a without tilting as in the conventional case. Also, it can be efficiently press-fitted. Further, since the new bearing member 17 contacts the existing bearing member 21 via the auxiliary ring-shaped member 23, the new bearing member 17
When the bearing is pressed into a predetermined position within the through hole 5a of the lever 5, the existing bearing member 21 can be easily pulled out from within the through hole 5a, and the outer diameter of the auxiliary ring-shaped member 23 is smaller than that of the through hole 5a. By making the diameter smaller than the inner diameter, the placement of the new bearing member 17 and the initial guidance into the through hole 5a become easy. Further, since the cylindrical body 22 has the step portion 22b formed on the side opposite to the existing bearing member of the new bearing member 17, and the step portion 22b can be inserted into the through hole 5a, the length of the step portion 22b in the axial direction is increased.
