Bearing apparatus for vehicle

In a construction in which a double row rolling bearing and a constant velocity joint (3) are mounted to a hub wheel (1), a fixing ring fixedly mounted to a vehicle-outer side opening of the hub wheel is sandwiched between a vehicle-outer side end face of an outer ring shaft of the constant velocity joint (3) and a bolt integrally mounted to the shaft in the axial direction, thereby coupling the outer ring of the constant velocity joint (3) to the hub wheel (1). In this case, a simple coupling operation only for mounting the bolt (9) to the shaft suffices, and a pre-load that has been applied to the rolling bearing is maintained invariably.
