PROBLEM TO BE SOLVED: To provide a vehicular wheel capable of suppressing a decrease in rigidity while sufficiently securing the capacity of an auxiliary air chamber.SOLUTION: In a vehicular wheel 1A, auxiliary air chambers SC1, SC2, SC3 and SC4 serving as helmholtz resonators are provided on an outer peripheral surface 11s of a rim 11. The rim 11 comprises hump parts H1 and H2 that protrude to the outside Z1 in a radial direction Z in a cross-sectional view in a width direction Y, a recess 31 that is formed between the hump parts H1 and H2, and a lid part 41 that forms the auxiliary air chambers SC1, SC2, SC3 and SC4 by connecting the hump parts H1 and H2 together and closing the recess 31.SELECTED DRAWING: Figure 1

    【課題】副気室の容量を十分に確保しつつ剛性低下を抑制することが可能な車両用ホイールを提供する。【解決手段】ヘルムホルツレゾネータとしての副気室SC1,SC2,SC3,SC4をリム11の外周面11sに設けた車両用ホイール1Aであって、リム11は、幅方向Yの断面視において、径方向Zの外側Z1に突出するハンプ部H1およびハンプ部H2と、ハンプ部H1とハンプ部H2との間に形成される凹み部31と、ハンプ部H1とハンプ部H2とを繋ぐとともに凹み部31を塞ぐことで副気室SC1,SC2,SC3,SC4を形成する蓋部41と、を備える。【選択図】図1
