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
