いる。On the drive side, the outer ring (1 ') is integrally formed with a mounting flange (5) for a vehicle body side member such as a knuckle,
The wheel hub (7) is press-fitted into the inner ring (6). Therefore, from the same viewpoint, the outer ring (1 ') on the drive side is also formed by forging, hardening, hardening, high carbon steel, forging, heat treatment, and grinding. Further, the wheel hub (7) is forged with structural carbon steel or the like to be integrally formed with the wheel mounting flange portion (7a), the brake rotor, and the wheel guide portion (7b), and is then machined and finished. There is.

に、高価となる。However, as mentioned above, the wheel mounting flange (2)
If the outer ring (1), (1 ') and the wheel hub (7) are integrally forged with the (7a) and the guide portions (3) and (7b) by carbon steel or the like, the weight of these becomes large, which is disadvantageous in terms of fuel consumption. It is also expensive.

ウジング（９）の内周に、軸受外輪（１″）をその外周
面及び端面が埋設されるように設けた自動車ホイール用
軸受が提案されている（実開昭63−3518号公報参照）。On the other hand, as shown in FIG. 6, a bearing outer ring (1 ″) is provided on the inner periphery of a cylindrical housing (9) made of a molding material, which is integrally provided with a flange (8) for wheel mounting on the outer periphery. A bearing for an automobile wheel has been proposed in which the surface and the end surface are embedded (see Japanese Utility Model Laid-Open No. 63-3518).

次のような問題点がある。In the automobile wheel bearing shown in FIG. 6, the tubular housing (9) is made of ordinary cast iron, malleable cast iron, light metal such as aluminum, or synthetic resin such as FRP, and the outer ring (1 ″) has a carbon content of 0.5% or more. It is supposed to be made from structural carbon steel, structural alloy steel such as manganese steel, or bearing steel.
If the tubular housing (9) is made of ordinary cast iron or malleable cast iron, the overall weight is as heavy as the integrally forged product. Also,
If the tubular housing (9) is made of light metal such as aluminum or synthetic resin such as FRP, the overall weight can be reduced. However, the wheel mounting flange (8) and the like are made of light metal as described above. If only made of materials such as FRP,
There are the following problems.

られない。That is, the weight of the vehicle body, the impact vibration from the tire, etc. are received by the bearing portion via the flange (8) surface of the tubular housing (9), so that the outer ring (1 ″) and the tubular housing (9) are embedded. Even if integrally formed, the contact surface may be repeatedly subjected to a load due to the difference in linear expansion coefficient and may be destroyed.
In addition, the brake rotor and wheels (not shown) can be attached using the hub bolts (10).
The torque of the hub bolt (10) must be fixed to the flange (8) so that the bolt (10) will not rotate when installing the brake rotor and wheel with only such materials as the torque required to prevent it from rotating. However, the idling torque) cannot be obtained.
