To provide a vehicular wheel including a plurality of sound absorbing air areas capable of exhibiting the effect of an action as a Helmholz resonance absorber.
In this vehicular wheel, by respectively attaching partitioning elastic pieces 31 in a plurality of fitting holes 22 communicated with a rim cavity part 21, an internal air area 24 inside the rim cavity part 21 is partitioned by fitting partition wall parts 32 of the partitioning elastic pieces 31, and the plurality of sound absorbing air areas 25 respectively communicated with tire internal air areas 102 by communication holes 37 of sealing parts 33 that seal the fitting holes 22 are formed. The Helmholz resonance absorber is configured by each of the sound absorbing air areas 25 and each of the communication holes 37 thereof, and by the effect of the action, cavernous resonance occurring in the tire internal air areas 102 can be reduced and road noise occurring during running of the vehicle can be reduced.
