To provide a bearing device for a wheel and an axle module capable of reducing circumferential play, in which a hub ring and an outer joint member of a constant velocity universal joint can be easily connected to each other, into which foreign matter (such as mud and salty water) is prevented from intruding to suppress internal rust, and which stably transmit torque over a long period.
Axially extending ridges 35 are provided either on the outer diameter surface of a shaft section 12 of the outer joint member or on the inner diameter surface 37 of a hole section 22 in the hub ring 1, and the ridges are axially press fitted to the other. This forms, in the other, the ridges 36 to be in close contact with the ridges 35 by the ridges 35, thereby forming a ridge-groove fitting structure M, in which the whole fitting and contacting area of the ridges 35 and grooves 36 are in close contact with each other. A wheel pilot section 97 fitted on the inner periphery of the wheel is constituted by a separate member from the hub ring 1. A coating film 81 is formed as a sealing member along the inner diameter surface on the outboard side of the hub ring 1 and the outer periphery of an edge on the outboard side of the shaft section 12 to close an opening on the outboard side of the hub ring 1.
