ABSTRACT:
A vehicle-use bearing device having a double row rolling bearing fitted around an outer peripheral surface of a hollow shaft portion of a hub wheel, wherein a held portion between an axially intermediate position and a vehicle outer side in the hollow shaft portion of the hub wheel is axially held between the axially intermediate position of an outer ring shaft portion of a constant velocity joint and the vehicle outer side so that a cup-shaped cylindrical portion of an outer ring of the constant velocity joint is free of contact with a caulked portion in the hollow shaft portion of the hub wheel at the shaft end on the vehicle inner side in order to connect the hub wheel with the constant velocity joint without a clearance, whereby an excessive preload which can affect a rolling performance of the double row rolling bearing is not imparted on the bearing.
