Abstract
A seal lip having: a cylindrical seal surface in close contact with an outer peripheral surface of an inner race with outer side and inner side surfaces standing upright respectively from an outer end and an inner end of the seal surface and reaching a lip supporting portion of a seal member, and protruding on an inner peripheral surface of the lip supporting portion. The outer side surface is a perpendicular surface standing upright from the outer end of the seal surface in a direction perpendicular to a generating line of the outer peripheral surface of the inner race. The inner side surface includes: a perpendicular surface standing upright from the inner end of the seal surface in parallel with the outer side surface; and a conical surface inclined toward the outer side surface extending outward in a radial direction from an outer peripheral end of the perpendicular surface.
