Abstract: A bearing seal includes: a ring-shaped outer seal portion; a ring-shaped inner seal portion provided inside the outer seal portion; a connecting portion for connecting the inner seal portion and the outer seal portion; and a ring-shaped rigid portion provided at the connecting portion. The outer seal portion, the inner seal portion, and the connecting portion are integrally formed of the same material consisting of an elastic material. The inner seal portion has rigidity higher than that of the outer seal portion, and has a ring-shaped seal surface gradually approaching a ring center axis of the inner seal portion while extending from a ring-shaped base end side connected to the connecting portion toward a distal end side. The inner seal portion is formed in a tapered cylindrical shape having the ring-shaped seal surface on an inner peripheral surface thereof, and has a thickness which gradually decreases from the base end side toward the distal end side.
