<P>PROBLEM TO BE SOLVED: To provide a method for enhancing the rigidity of a wheel while suppressing an increase of weight of the wheel and the increase of the inertial moment in a wheel rotation direction. <P>SOLUTION: A motorcycle wheel includes a hub 31 supported by an axle, a rim 32 on which a tire is mounted, main spokes 33 extending from the hub to the rim as a plurality of spokes connecting the hub with the rim, and sub spokes 34 extending from the hub to the main spokes. The main spokes are inclined in one wheel circumferential direction from the hub toward the outside of the wheel radial direction with respect to a straight line M1 connecting a coupling portion between the main spoke and the hub with a wheel rotational center O1. The sub spokes is inclined in the other wheel circumferential direction from the hub toward the outside of a wheel radial direction with respect to a straight line M3 connecting a coupling portion between the sub spoke and the hub with the wheel rotational center. <P>COPYRIGHT: (C)2013,JPO&INPIT |
