This has a rim B integrated on the outer peripheral portion by joining the left and right rim components B ′ and B ′ to each other, and each rim component B ′ and B ′ has a rim bottom portion B1. A flange portion B2 that rises from the outer end in the width direction, a joint portion B4 that extends radially inward from the rim bottom portion B2, and a mounting portion B5 that extends radially inward from the joint portion B4 are uniform. It is integrally formed by pressing a plate material having a thickness.

There is a problem that the two rim components B ′ are superposed on each other at the joining portion B4 and the attaching portion B5, so that the thickness increases and the weight increases. In order to solve such a problem, it may be possible to reduce the weight by forming each of the rim components B ′ and B ′ with a thinner plate material, but in this case, the strength of the rim B becomes weak and the tire A There is an adverse effect that the holding power of is reduced. In particular, when the flange outer end B3 is engaged with the tire outer surface as described above, the thin outer end B3 is easily deformed, and a sufficient caulking action cannot be obtained.

The relative positions of the insertion hole B6 and the bolt insertion hole B7 of the mounting portion B5 must be strictly adjusted to form a hole, which requires considerable precision.
The productivity deteriorated, and it was troublesome because all the holes had to be joined together during assembly. Further, in the case of a wheel of a type in which the mounting portion B5 is offset in the axial direction, the left and right rim components B'and B'are asymmetric, and the left and right rim components B'have to be bent by different press dies. However, there is also a problem that the manufacturing cost rises.

ることを特徴とするものである。The present invention has taken the following technical means in order to achieve the above object. That is, the present invention relates to a tire wheel having an outer peripheral portion with a rim 3 integrated by joining left and right rim structures 20, and one of the rim structures 20 has both rim structures. It is characterized in that a mounting portion 14 is provided which extends radially inward from the joint portion of 20 and is mounted on the axle side of the vehicle.

The weight of can be reduced.
Further, even when the mounting portion 14 is formed with a bolt insertion hole for mounting on the axle side, it is not necessary to strictly match the bolt insertion holes of both rim structures as in the conventional case, so that the hole is not necessary. The processing accuracy is eased and the assembly work is easy. The rim 3 has a flange portion 11 that rises radially outward from both sides in the width direction of the rim bottom portion 10, and an engagement portion 13 that protrudes inward in the width direction from the flange portion 11 and engages with the tire outer surface. The engaging portion 13 is the mounting portion 14
It is preferable that they are formed to have substantially the same thickness.

Sufficient, it is possible to reduce the manufacturing cost.

Is inclined so as to widen outward in the width direction as it goes radially outward from the base end, and the radial outer end is further curved outward. Tire body 2
Has a lateral width that increases from a radially inner portion sandwiched by the flange portions 11 on both sides to a radially outer portion that protrudes from the flange portion 11, and the core portion 6 also follows the outer shape of the tire body 2. The outer side in the radial direction is widened so as to substantially follow the outwardly widening shape of the flange portion 11. Engaging part 13
Is formed at a midway portion in the radial direction of the flange portion 11 and is located radially inward of the core portion 6 of the tire body 2, and the height t1 from the rim bottom portion 10 is
10% or less of the height t2 of the rim from the rim bottom portion 10 (t1 ≦

This makes it possible to reduce the weight and improve cushioning. Further, the flange portion 11 rises to the outside in the radial direction higher than the inner peripheral surface 6A of the core portion 6, and supports the radial range S including the core portion 6 having relatively low rigidity from both widthwise sides. As a result, it is possible to suppress deformation when lateral force is applied as much as possible, whereby side slip and rim displacement can be appropriately prevented.

It is possible to further strengthen the connection between the rim 3 and the tire main body 2. Further, it is possible to prevent cracks and the like from occurring from the concave portion 7 (engagement portion) having a large change in cross section as much as possible. The engaging portion 13 may be continuous over the circumferential direction of the rim 3, or may be partially formed at intervals in the circumferential direction.
