Abstract

A vehicle wheel includes a main body fitted between a first vertical wall surface and a second vertical wall surface of the wheel, a first flange portion extending from the main body toward the first vertical wall surface, and a second flange portion extending from the main body toward the second vertical wall surface. In the vehicle wheel, a length of one of the flange portions is made shorter than a length of the other flange portion in a wheel width direction.

First claim

We claim:

1. A vehicle wheel comprising:
a well portion;
a sub air chamber member disposed on an outer circumferential surface of the well portion, the sub air chamber member functioning as a Helmholtz resonator in a tire air chamber;
a vertical wall being provided to stand on the outer circumferential surface of the well portion, the vertical wall having a first vertical wall surface extending in a circumferential direction of the outer circumferential surface,
wherein the well portion including a rising portion, the rising portion including a second vertical wall surface extending in the circumferential direction and being opposite to the first vertical wall surface in a width direction of the outer circumferential surface, wherein
the first vertical wall surface includes a first groove portion extending in the circumferential direction and the second vertical wall surface includes a second groove portion extending in the circumferential direction,
the sub air chamber member is fitted between the first vertical wall surface and the second vertical wall surface and includes:
a main body formed of resin and including a sub air chamber and a communication hole communicating the sub air chamber with the tire air chamber;
a first flange portion extending from the main body toward the first vertical wall surface and extending in the circumferential direction, the first flange portion being engaged with the first groove portion of the first vertical wall surface; and
a second flange portion extending from the main body toward the second vertical wall surface and extending in the circumferential direction, the second flange portion being engaged with the second groove portion of the second vertical wall surface,

in a state in which one of the first flange portion and the second flange portion is caused to be partially engaged in the corresponding one of the first groove portion and the second groove portion, the other of the first flange portion and the second flange portion is entirely pressed toward the outer circumferential surface to cause the one of the first flange portion and the second flange portion to be engaged in the corresponding one of the first groove portion and the second groove portion and cause the other of the first flange portion and the second flange portion to be engaged in the corresponding one of the first groove portion and the second groove portion, such that the sub air chamber member is secured to the outer circumferential surface, and
wherein the one of the first flange portion and the second flange portion includes a length in the width direction shorter than a length of the other of the first flange portion and the second flange portion.

2. The vehicle wheel according to claim 1 , comprising a pair of the sub air chamber members disposed so as to face each other across a wheel center of rotation.

3. The vehicle wheel according to claim 1 , wherein the one of the first flange portion and the second flange portion is disposed adjacent to the sub air chamber.
