PROBLEM TO BE SOLVED: To provide a vehicle wheel capable of improving rigidity and strength. SOLUTION: A taper part 11 having an outside diameter decreased toward a tip part 8a of a rise part 8 is formed on the outer peripheral side of the tip of the rise part 8. An inside diameter IT is not less than an outside diameter OS of the tip part of the taper part 11 and is smaller than an outside diameter OK, being set such that [OS<=IT<OK]. A bottom 5 of a well part 4 of a rim 2 is guided by the taper part 11 and fitting-in between the rim 2 and a disc 3 is smoothly progressed without high resistance. Further, a fitting-in margin can be increased to a high value, and along with this increase, rigidity of the fit-in part is increased and two members are fitted in each other with a strong force. Thereby, a durable strength is improved and a wheel 1 for the vehicle can be provided as that for a large or a middle truck and that for a middle bus.
