Abstract
Prior to assembly of an elastic member (51) to a slinger (52), a radially inner surface (58) of a first portion (56) is formed in a concave shape, and a radially inner surface (59) of a second portion (57) is formed in a conical shape. The second axial lip (55) is adapted such that, after the elastic member (51) is assembled to the slinger (52) and when a second axial lip (55) is in a not-yet-worn state, the second axial lip (55) does not come into contact with a fixation section (65) of the slinger (52).
