Abstract
To reduce a sliding resistance to the rotation member, and whereby to reduce a torque, a thickness of an inner diameter side lip is formed to be larger than a thickness of an outer diameter side lip, and the outer diameter side lip is formed thinner than the inner diameter side lip in thickness. A depression for inhibiting both the lips from pulling at each other is provided between the inner diameter side lip and the grease lip. A bent portion for reducing a close contact load applied to a rotation member is provided in an intermediate portion in a longitudinal direction of the inner diameter side lip.
