| 20110316324 | VEHICLE WHEEL - A vehicle wheel having a rim and a disk. A disk flange of the disk may have a non-contact portion non-contacting a radially inner surface of the rim, at a radially outer extension of a width center line of a spoke. As a result, the rigidity of a portion of the disk in the circumferential direction of the wheel where the spoke is provided may be decreased compared with a wheel (conventional) where such non-contact portion is not provided. A difference in rigidity of the disk in the circumferential direction of the wheel between a portion where the vent window is provided and a portion where the spoke is provided may be smaller than that in the case of the conventional wheel, whereby a durability of the wheel and a run-out accuracy of the wheel may be improved. | 12-29-2011 |
