Vehicle wheel

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, and
• a top of the vertical wall is lower than a top of a hump on the side of the second vertical wall from the outer circumferential surface, and wherein the upper surface of the body is formed to extend along and inside in a wheel diametrical direction a line connecting the top of the vertical wall to the top of the hump on the side of the second vertical wall.
