1. A vehicle wheel including an additional air chamber member on an outer circumferential surface of a well functioning as a Helmholtz resonator in a tire air chamber, comprising:
a first vertical wall surface formed on a vertical wall which stands up on an outer circumferential surface of the well to extend in a circumferential direction of the outer circumferential surface, a second vertical wall surface formed on one rising part of the well to extend in a circumferential direction of the outer circumferential surface so as to face the first vertical wall surface in the width direction of the outer circumferential surface, wherein a part between the vertical wall and another rising part of the well is used for drop a tire bead thereon while the tire is being attached to the vehicle wheel; wherein the additional air chamber member comprising a body fitted into the first vertical wall surface and a second vertical wall, including an additional air chamber and a communication through hole for communication between the additional air chamber with a tire air chamber, and a fastening part, formed on the both sides of the body configured to fasten the body between the first vertical wall surface and the second vertical wall surface, wherein in the cross section of the body in the width direction, an upper surface of the body inclines to have an upward slope from a side of the first vertical wall surface to a side of the second vertical wall surface. |
