| 摘要 |
A hollow cylindrical pilot section (72) to be fitted in the inner periphery of a wheel (80) is formed on an inner diameter section of a brake rotor (70). By doing so, the shape of a hub ring, particularly its shape on the outboard side, is simplified, and as a result, the hub ring can be produced at low cost by cold forging etc. |
