A rolling bearing has a metallic member sealing member at one axial end thereof. The sealing member has a first cylinder section including a first cylinder section facing surface which is in contact with an outer peripheral surface of an inner ring, a second cylinder section connected to the first cylinder section and including a second cylinder section facing surface which faces the outer peripheral surface of the inner ring, and a flange section connected to the second cylinder section via a bend section. In a state before the sealing member is press fitted in the bearing, a radial position of the second cylinder section facing surface is closer to the flange section than a radial position of the first cylinder section facing surface. The rolling bearing has another metallic member sealing member at another axial end thereof.

Rolling bearing

This sealing device has an annular metal core portion and an annular elastic portion. The elastic portion has a thick portion and a thin portion which extends from the thick portion in an axial direction of the elastic portion and has a thinner thickness in a radial direction than the thick portion. A fixed lip is provided on an inner peripheral surface of the thick portion, and a sliding lip is provided on an inner peripheral surface of the thin portion.
