The elastic material portion has a side lip formed so as to contact a slinger from the inside, a radial lip formed so as to contact the slinger from an outer periphery side, and an outer peripheral annular projection being an annular projection which is arranged on an outer periphery side of the side lip and protrudes to the outside. The slinger has a fitting portion and a flange portion extending from an outer end portion of the fitting portion to the outer periphery side. The elastic material portion forms a labyrinth seal between the outer peripheral annular projection and the side lip between the elastic material portion and the flange portion of the slinger.
