Abstract

A seal lip part (9) includes a lip main body part (9a) and a protruding portion (16) that protrudes in the radial direction from the circumferential edge of the lip main body part (9a) and makes sliding contact with an inner ring (1). The protruding portion (16) comprises a high abrasion material which exhibits a light degree of contact such that the protruding portion (16) is abraded so as to be not in contact or such that the contact pressure can be considered to be zero when the bearing is used in a state of rotation. A fitting portion (13) which is fitted into a seal attachment groove (2b) of a seal member main body (8) is formed with a concomitant rotation preventing fitted shape such that when the protruding portion (16) makes sliding contact the fitting portion does not generate movement in the circumferential direction due to concomitant rotation with respect to the outer ring (2).
