In a vehicle wheel 1, the communication through holes 20a, 20b, 20c, 20d of the first Helmholtz resonators 19a, 19b,19c,19d are arranged at an angle interval of approximately 90 degrees around a wheel rotation center Ax. The Helmholtz resonators 19a, 19b are formed integrally each other to form the first additional air chamber member 10a. The Helmholtz resonators 19c, 19d are formed integrally each other to form the second additional air chamber member 10b. The additional air chamber member 10a, 10b includes two additional air chambers SC therein. Each of the communication through holes 20a, 20b, 20c, 20d communicates the tire air chamber MC individually. |
