Bearing device for driving wheel
First Claim
1. A bearing device for a driving wheel comprising:
- an outer member on an inner peripheral surface of which raceways in double rows are formed;
an inner member on an outer peripheral surface of which raceways opposing to the raceways of the outer member and a wheel mounting flange are formed;
rolling elements of double rows provided between each of the raceways of the outer member and the inner member; and
a constant velocity universal joint having a joint outer ring of which a shaft portion is inserted into the inner member in such a manner that torque is transmittable, the bearing device rotatably supporting a wheel on an automobile body, wherein a pilot portion of the bearing device provides a clearance between a base part of the shaft portion of the joint outer ring and an end portion of the inner member wherein the clearance of the pilot portion is 0.4 mm or less.
