A bearing device for a vehicle wheel, comprising: an outer member having a plurality of rows of outer raceway surfaces at an inner periphery; an inner member that includes a hub ring having a small diameter step part extending in an axial direction at an outer periphery and at least one inner ring press-fitted into the small diameter step part of the hub ring, and that has, at the outer periphery, a plurality of rows of inner raceway surfaces (3d, 4a) facing the plurality of rows of outer raceway surfaces; a plurality of rows of rolling elements rollably housed between the respective raceway surfaces of the inner member and the outer member; and a sealing member (6, 7) that blocks an opening end of an annular space formed by the outer member and the inner member, wherein the sealing member (6, 7) has a core metal (64, 71) fitted to the outer member and an elastic member (65, 72) joined to the core metal (64, 71), the elastic member (65, 72) has a pressing part (654, 724) joined to a first joint surface (64g, 71e), which is a part of an axially outer surface of the core metal (64, 71), and pressed inward in the axial direction when the sealing member (6, 7) is press-fitted into the outer member, and a non-pressing part (655, 725) joined to a second joint surface (64h, 71f), which is a part of the axially outer surface of the core metal (64, 71) and adjacent to the first joint surface (64g, 71e), and not pressed inward in the axial direction when the sealing member (6, 7) is press-fitted into the outer member, characterized in that an axial thickness (T1, T5) of the pressing part (654, 724) is thinner than an axial thickness (T2, T6) of the non-pressing part (655, 725). an outer member having a plurality of rows of outer raceway surfaces at an inner periphery; an inner member that includes a hub ring having a small diameter step part extending in an axial direction at an outer periphery and at least one inner ring press-fitted into the small diameter step part of the hub ring, and that has, at the outer periphery, a plurality of rows of inner raceway surfaces (3d, 4a) facing the plurality of rows of outer raceway surfaces; a plurality of rows of rolling elements rollably housed between the respective raceway surfaces of the inner member and the outer member; and a sealing member (6, 7) that blocks an opening end of an annular space formed by the outer member and the inner member, wherein the sealing member (6, 7) has a core metal (64, 71) fitted to the outer member and an elastic member (65, 72) joined to the core metal (64, 71), the elastic member (65, 72) has a pressing part (654, 724) joined to a first joint surface (64g, 71e), which is a part of an axially outer surface of the core metal (64, 71), and pressed inward in the axial direction when the sealing member (6, 7) is press-fitted into the outer member, and a non-pressing part (655, 725) joined to a second joint surface (64h, 71f), which is a part of the axially outer surface of the core metal (64, 71) and adjacent to the first joint surface (64g, 71e), and not pressed inward in the axial direction when the sealing member (6, 7) is press-fitted into the outer member, characterized in that an axial thickness (T1, T5) of the pressing part (654, 724) is thinner than an axial thickness (T2, T6) of the non-pressing part (655, 725).
