PROBLEM TO BE SOLVED: To provide a bearing device for a wheel capable of securely fixing a pulser ring by a simple configuration without increasing the number of parts. SOLUTION: In this bearing device for the wheel having a wheel mounting flange 4b for mounting the wheel at the outer periphery of one end part integrally and press-fitting the pulser ring 10 into the outer periphery of the other end part, the pulser ring 10 is formed by sintered alloy, forms recessed and projecting parts 10a formed and arranged at an equal interval in the peripheral direction at the outer periphery, forms a plurality of grooves 11 in the axial direction at the inner periphery, forms an additionally tightening part 12 by deforming the other end part of an outward member 4 corresponding to the groove 11 in the axial direction plastically, and is fixed to the outward member 4 in the axial direction by this additionally tightening part 12. Consequently, detent of the pulser ring 10 is performed at the same time, and the pulser ring 10 can be securely fixed to the outward member 4 by the simple configuration without increasing the number of parts.
