3. The bearing device for a driven wheel according to claim 2, wherein the end portion of the hub wheel is crimped and the inner ring is non-separably integrated.
4. The bearing device for a driven wheel according to any one of claims 1 to 3, wherein the hollow portion is a blind hole.
5. The bearing device for a driven wheel according to claim 4, wherein the bottom of the hollow portion is arranged on the inner ring side.
6. The bearing device for a driven wheel according to any one of claims 1 to 5, wherein the hollow portion has an unequal diameter according to the wall thickness of the inner member.
7. The driven wheel bearing device according to claim 6, further comprising a tapered hollow portion whose inboard side gradually decreases.
8. The driven wheel bearing device according to claim 6, which has a stepped hollow portion.
9. The bearing device for a driven wheel according to any one of claims 1 to 8, wherein a vehicle body mounting flange is formed on an outer member.
10. A seal member that seals the internal space of the bearing is attached to the opening of the outer member.
The bearing device for a driven wheel according to claim 2.
11. The driven wheel according to claim 10, wherein the seal member is brought into contact with the outer peripheral surface of the hub wheel.

上記軸受装置の軸方向寸法をコンパクト化するため、内方部材を、中空のハブ輪とハブ輪の外周に圧入した内輪とで構成し、内方部材の複列の軌道面のうちの一方をハブ輪の外周に、他方を内輪の外周に形成することもできる。この場合、ハブ輪の外周には、内輪を圧入するための小径段部が設けられる。外方部材の開口部には、軸受の内部空間を密封す るシール部材が装着される。このシール部材は、ハブ輪の外周面に接触させたり、内輪の 外周面に接触させたりすることができる。 In order to make the axial dimension of the bearing device compact, the inner member is composed of a hollow hub ring and an inner ring press-fitted into the outer circumference of the hub ring, and one of the raceway surfaces of the double rows of the inner member is formed. It is also possible to form the other on the outer circumference of the hub ring and the other on the outer circumference of the inner ring. In this case, a small diameter step portion for press-fitting the inner ring is provided on the outer periphery of the hub ring. The opening of the outer member, the sealing member is mounted you seal the inner space of the bearing. This sealing member can be brought into contact with the outer peripheral surface of the hub ring or the outer peripheral surface of the inner ring.
