Claims

[Scope of utility model registration request]

When joining an external member with an outer rim and an internal member with an inner rim, the inward rim flanges extending from each rim face each other and are joined together with the wheel disc forming member using bolts and nuts. In the vehicle wheel, the rim flange extends radially inward from a position approximately corresponding to the rim diameter of the outer rim and the inner rim, and the rim well that receives the tire when installing or removing the tire supports the bolts and nuts protruding from the rim flange. is provided on the inner rim at a position beyond the wheel width direction,
The bolt/nut is arranged such that at least a portion of the bolt head or nut located between the rim flange and the rim well is located outside the bottom position of the rim well in the wheel radial direction, and The joint part facing the inner surface of the tire is sealed by welding, and the distance from the weld part on the side where the tire is introduced to the outer edge of the bead seat of the outer rim corresponds to the bead width of the tire. A vehicle wheel characterized in that the dimensions of the bead seat portion are determined, and the welded portion forms a hump for locking a tire bead.
