In a vehicle wheel (1), communication holes (18a) of first Helmholtz resonators (auxiliary air chamber members 10a, 10d) having a resonant frequency lower by a first prescribed frequency (∆fa) than the resonant frequency of air column resonance sounds of a tire, and communication holes (18a) of second Helmholtz resonators (auxiliary air chamber members 10b, 10c) having a resonant frequency higher by a second prescribed frequency (∆fb) than the resonant frequency of air column resonance sounds of the tire, are arranged facing each other across the wheel rotational center (AX), the second prescribed frequency (∆fb) being set greater than the first prescribed frequency (∆fa). |
