側（タイヤ２５側）とを連通させて、タイヤ２５内の空
気の移動を大きく確保し、タイヤ２５による緩衝性を拡
大させているものが存在する。As shown in FIG. 2, in the vehicle wheel, an independent chamber 31 is provided in the disc portion 11, and the independent chamber 31 and the outside of the rim R (tire 25 side) are communicated with each other to drain the air inside the tire 25. There is one that ensures a large amount of movement and expands the cushioning properties of the tires 25.

を確保しにくいという不都合を有した。However, in the conventional vehicle wheel W, since it is necessary to ensure airtightness of the independent chamber 31 in the disc part 11, when the fixing bolt 7 penetrates the disc part 11, this fixation occurs. It was necessary to prevent the bolt 7 from crossing the independent chamber 31. For this reason, the independent chamber 31 cannot be provided in the bolt penetration portion of the disk portion 11, and it is difficult to increase the volume of the independent chamber 31. As a result, in the conventional vehicle wheel W, the tire 25 has a large capacity. This had the disadvantage that it was difficult to ensure buffering properties.
