## Abstract

A vehicle wheel includes: a rim including a well portion and a guide member; and a sub-air chamber member serving as a Helmholtz resonator. The well portion has an outer circumferential surface extending in a wheel circumferential direction of the vehicle wheel. The guide member engages with the sub-air chamber member to guide the sub-air chamber member on the outer circumferential surface in the wheel circumferential direction, thereby to attach the sub-air chamber member to the rim.

## Claims

### Claim 1

A vehicle wheel comprising:
a rim comprising a well portion and a guide member, the well portion having an outer circumferential surface extending in a wheel circumferential direction of the vehicle wheel; and
a sub-air chamber member serving as a Helmholtz resonator,
wherein the guide member engages with the sub-air chamber member to guide the sub-air chamber member on the outer circumferential surface in the wheel circumferential direction, thereby to attach the sub-air chamber member to the rim,
wherein the sub-air chamber member has a wheel radial direction outer surface,
wherein the guide member has a wheel radial direction inner surface extending in the wheel circumferential direction and facing the wheel radial direction outer surface of the sub-air chamber member,
wherein the rim has an installation opening which is defined by and between the wheel radial direction inner surface of the guide member and the outer circumferential surface of the well portion and through which the sub-air chamber member is installed in the wheel circumferential direction,
wherein the wheel radial direction inner surface of the guide member and the outer circumferential surface of the well portion define a distance therebetween that gradually decreases from the installation opening in the wheel circumferential direction in which the sub-air chamber member is installed, and
wherein the sub-air chamber member has a wheel radial direction height that gradually decreases in the wheel circumferential direction corresponding to the distance between the wheel radial direction inner surface of the guide member and the outer circumferential surface of the well portion.

### Claim 2 (depends on 1)

The vehicle wheel according to claim 1,
wherein the sub-air chamber member has two side surfaces which are located opposite each other in the wheel width direction and on each of which a rib extending in the wheel circumferential direction is formed, and
wherein the wheel radial direction outer surface of the sub-air chamber member is constituted by wheel radial direction outer surfaces of the ribs.

### Claim 3 (depends on 1)

The vehicle wheel according to claim 1,
wherein the sub-air chamber member has engaging projections which are formed on the wheel radial direction outer surface of the sub-air chamber member and which are to be engaged with the guide member.
