Abstract
An inner diameter-side cylindrical memberof a supporting ringis externally fitted on a shoulderof an inner ringconstituting a hub. An encoderis supported on the outer peripheral surface of an outer diameter-side cylindrical portionconstituting the supporting ring. Further, to a metal coreinternally fitted to an outer ringis supported and fixed a rotation-detecting sensor, and also a proximal end portion of a seal memberis connected and fixed thereto. An edge of at least one of seal lipsof the seal memberis brought to be in sliding contact with the supporting ringaround the entire circumference. Since the rotation-detecting sensorand the seal memberare supported by the core metal, a rolling bearing unit can be downsized. Further, since the encoderis placed on the outer peripheral surface of the outer diameter-side cylindrical portion, the width dimension of a surface with which the edge of each of the seal lipsis brought to be in sliding contact is secured for excellent sealing ability. The structure provides a rolling bearing unit with a rotating speed-detecting device, where the bearing unit is downsized and has a construction capable of achieving excellent sealing ability.
