特性を低下させることが懸念される。ここに改良の余地
がある。In the above conventional example, since the entire outer surface of the inner ring 84 of the bearing 82 is hardened, the caulking load must be reduced in order to increase the drag force of the bearing 82 due to caulking. It had to be set stronger than necessary. For this reason, there is a possibility that distortion occurs on the raceway surface of the inner race 84, and in extreme cases, there is a concern that the rolling characteristics of the bearing 84 may be reduced. There is room for improvement here.
