摘要： A first fit portion (11) and a second fit portion (15) of an inner ring (1) according to the invention have a spring property. Therefore, the first and second fit portions (11, 15) may be flexed radially outward by elasticity thereof and then fitted to a shaft (20). Thus, the inner ring (1) is tightly fitted to the shaft (20) with a set interference with respect to the shaft (20). Accordingly, it is easy to fit/remove the inner ring (1) to/from the shaft (20). Therefore, an outer peripheral face of the shaft (20) is pushed radially inward by elasticity of the first and second fit portions (11, 15), that is, the inner ring (1) is tightly fitted to the shaft (20), without reducing the ease of fitting/removing the inner ring (1) to/from the shaft (20). As a result, it is possible to minimize generation of creep.
摘要翻译：根据本发明的内圈（1）的第一配合部分（11）和第二配合部分（15）具有弹性。因此，第一和第二配合部分（11,15）可以通过其弹性而径向向外弯曲，然后装配到轴（20）。因此，内圈（1）以相对于轴（20）设定的干涉紧密地配合到轴（20）。因此，容易将内圈（1）装配到轴（20）上。因此，轴（20）的外周面通过第一和第二配合部（11,15）的弹性被径向向内推压，即内圈（1）紧密地配合到轴（20）上，而不减少将内圈（1）装配到轴（20）的方式。结果，可以最小化蠕变的产生。
