<P>PROBLEM TO BE SOLVED: To provide a wheel for a vehicle having large diameter, lightweight and high mechanical strength. <P>SOLUTION: The wheel for the vehicle is composed of a rim part 22 having a mounted tire, a disc part 21 mounted to an axle, and a cross part 25 forming a crossing portion of the both, and is casted in the forming space 14 continued to at least a pair of side gates 16a, 16b. DASII(Do) of the outer peripheral side of the cross part 25 has an equal value to DASII (Di) of the inner peripheral side or larger than that. The difference between Do and Di at the middle position of the position of the side gate and the position furthest from the side gate each other is lager than the difference between Do and Di at the position of the side gate. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
