## Abstract

A vehicle wheel is provided which includes a sub air chamber member capable of suppressing a surface deformation amount in case of an action of an internal pressure of the sub air chamber member. A sub air chamber member of a vehicle wheel includes an upper surface member, a lower surface member, and bridge sections causing the upper surface member and the lower surface member to strike on each other. An end-to-end distance of an opening part of a bridge section opening on an upper surface of the upper surface member is set longer than a distance to an end portion of an opening part of another bridge section adjacent thereto. Moreover, the area of the opening parts of the bridge sections opening on the upper surface of the upper surface member is larger than the area of other general parts.

## Claims

### Claim 1

A vehicle wheel comprising:
a sub air chamber member as a Helmholtz resonator located in a tire air chamber and on an outer peripheral surface of a well portion, the sub air chamber member including
an upper surface member disposed inside the tire air chamber,
a lower surface member disposed on an outer peripheral surface side of the well portion, and
a plurality of bridge sections formed by causing the upper surface member and the lower surface member to strike on and get joined to each other, wherein
an end-to-end distance of an opening part of a certain one of the bridge sections opening on an upper surface of the upper surface member is set longer than a distance to an end portion of an opening part of a different one of the bridge sections adjacent to the certain bridge section.

### Claim 2 (depends on 1)

The vehicle wheel according to claim 1, wherein an area of the opening parts of the bridge sections opening on the upper surface of the upper surface member is larger than an area of other general parts.

### Claim 3 (depends on 1)

The vehicle wheel according to claim 1, wherein each bridge section is formed into a fan shape in which a distance between two opposed side surfaces becomes longer as the side surfaces come closer to the upper surface of the upper surface member.

### Claim 4 (depends on 1)

The vehicle wheel according to claim 1, wherein, in each bridge section, only the upper surface member is recessed toward the lower surface member and strikes on the lower surface member.

### Claim 5 (depends on 1)

The vehicle wheel according to claim 1, wherein
the sub air chamber member includes an engagement portion provided at an end portion of the sub air chamber member and designed to be engaged with the well portion, and
the end-to-end distance of the opening part of each bridge section opening on the upper surface of the upper surface member is set longer than a distance from an end portion of the opening part of the bridge section to the engagement portion.

### Claim 6 (depends on 2)

The vehicle wheel according to claim 2, wherein each bridge section is formed into a fan shape in which a distance between two opposed side surfaces becomes longer as the side surfaces come closer to the upper surface of the upper surface member.

### Claim 7 (depends on 2)

The vehicle wheel according to claim 2, wherein, in each bridge section, only the upper surface member is recessed toward the lower surface member and strikes on the lower surface member.

### Claim 8 (depends on 3)

The vehicle wheel according to claim 3, wherein, in each bridge section, only the upper surface member is recessed toward the lower surface member and strikes on the lower surface member.
