To provide a vehicular wheel capable of demonstrating the desired durability while suppressing the time and the cost required for the welding of a wheel disk to a wheel rim.
In the vehicular wheel 1, a disk flange part 9 alternately and continuously formed of curved recessed edges 21 and circumferential arc edges 22 has a weld extension part 23 extending from the circumferential arc edges 22 to a back side of the wheel. The weld extension part 23 is welded to a drop part 17 by forming a weld bead 25 so that a weld starting part 25a and a weld terminating part 25b are respectively located on both sides in the width direction of the weld extension part 23 and not brought into contact with the circumferential arc edges 22. In this constitution, the load applied to the weld starting part 25a and the weld terminating part 25b can be reduced while a vehicle travels, and the durability can be enhanced. Further, the length of the weld bead 25 can be suppressed, and the time and the cost required for the welding process can be suppressed.
