Claims

[Scope of utility model registration request]

an outer ring having an inner double-row track on the inside and a flange for mounting on the vehicle on the outer periphery; and an outer ring that corresponds to the inner inner track of the double-row track by extending a part of the outer ring of the constant velocity joint. The second cylindrical portion of a hollow wheel hub consisting of a first inner ring serving as a raceway, a first small-diameter cylindrical portion, a second large-diameter cylindrical portion, and a radially outward flange is placed on the outside of the double-row raceway. The second outer orbit corresponds to the inner orbit.
and a rolling element interposed between the inner and outer raceways, and furthermore, serrations are carved on the inner circumferential surface of the extension part of the constant velocity joint outer ring and the outer circumferential surface of the first cylindrical portion of the wheel hub, respectively. The two inner rings are fitted with serrations, and a nut is fixed to the bottom of the outer ring of the constant feed joint, and a bolt is screwed into the nut from the outside of the hollow part of the wheel hub to connect the first inner ring to the first inner ring. A foil bearing unit formed by integrally forming a double row rolling bearing by abutting and tightening a second inner ring.
