Provided is 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 (1) for a wheel comprises an inner sealing member (6) that blocks an inner opening end of an annular space (S) formed by an outer ring (2) and an inner ring (4). A sealing ring (62) of the inner sealing member (6) has a core metal (64) fitting in the outer ring (2) and an elastic member (65) joined to the core metal (64). The elastic member (65) has: a pressing part (654) that is pressed inward in the axial direction when the sealing ring (62) is press-fitted into the outer ring (2); and a non-pressing part (655) that is not pressed inward in the axial direction when the sealing ring (62) is press-fitted into the outer ring (2), wherein the axial thickness (T1) of the pressing part (654) is thinner than the axial thickness (T2) of the non-pressing part (655).
