Abstract
A bearing apparatus is provided for a driven shaft of an automobile. It includes a rotational speed detector for detecting a rotational speed of a wheel of the automobile by detecting the rotational speed of a circular detected member which has a plurality of projections provided at even intervals in the circumferential direction. The detected member is fixed to one end of a driven shaft. The other end of the driven shaft includes a flange for mounting of a wheel. The shaft is part of an inside member which is rotatably supported by an outside member fixed to a chassis through a plurality of rolling elements. Detected speed is sent to an antilock brake system through a connector. The rotational speed detector, a cover fit to the outside member to enclose at least those parts of the rotational speed detector and detected member which are in opposition, and the connector are embedded in a resin block by a plastic molding technique such that they have a fixed relationship to each other so as to provide an assembly of unitary construction.
