摘要：
[PROBLEMS] A bearing device for a drive wheel, having improved workability in assembly and capable of being delivered to automobile manufacturers as an axle module. [MEANS FOR SOLVING PROBLEMS] The bearing device is of a fourth- generation structure in which a hub ring (1) and an outer joint member (14) are integrally plastically joined together. A sensor (22) is inserted in an installation hole (21) formed in a knuckle (N), radially penetrating it. A pulser ring (23) is installed on the outer peripheral surface of the outer joint member (14) so as to face the sensor (22) with a predetermined radial gap in between them. The pulser ring (23) is constructed from a support ring (24) annularly formed of a steel plate by press working and from a magnetic encoder (25) joined to the support ring (24). The magnetic encoder (25) is made from an elastomer mixed with magnetic powder. Magnetic poles are alternately formed on the magnetic encoder (25) in its circumferential direction. The diameter d of the magnetic encoder (25) is set smaller than the inner diameter D of the knuckle (N).
