Abstract: A bearing device for a wheel, which has improved axial assembly accuracy of a sealing member by reducing the amount of springback. The bearing device for a wheel comprises an inner sealing member that blocks an inner opening end of an annular space formed by an outer ring and an inner ring. A sealing ring of the inner sealing member has a core metal fitting in the outer ring and an elastic member joined to the core metal. The elastic member has: a pressing part that is pressed inward in the axial direction when the sealing ring is press-fitted into the outer ring; and a non-pressing part that is not pressed inward in the axial direction when the sealing ring is press-fitted into the outer ring, wherein the axial thickness of the pressing part is thinner than the axial thickness of the non-pressing part.
