PROBLEM TO BE SOLVED: To provide a vehicular wheel which can install a plurality of resonators that can reliably attenuate air column resonance energy in tire inner spaces at low cost. ! SOLUTION: A vehicular wheel 1 is provided with a plurality of resonators 31 to 34 extending along an outer periphery of a rim 10 at 180° or more in a circumferential direction. The respective resonators 31 to 34 have pipes 35 of the same cross-sectional shapes along an extension direction, and both ends of the pipes 35 are closed by lids (blocking means). Internal spaces of the pipes 35 are provided as sub air chambers 37. On peripheral walls of the pipes 35, communication holes 38 which join the sub air chambers 37 to a main air chamber 2 composed of tire inner spaces are formed. The resonators 31 to 34 are arranged in an axial direction of the vehicular wheel 1 and arranged displaced in a circumferential direction at a prescribed angle respectively. !
