ク部３とリム部２および）・ブ部４との連設部Ｉ。A wheel body 1 of a vehicle wheel is lightweight by integrally molding a rim portion 2, spoke portions 3, and hub portion 4 from fiber-reinforced resin. Furthermore, it has a structure in which symmetrical half bodies 1a+1b, which are obtained by dividing the rim part 2 and spoke part 3 of the single wheel body in a direction perpendicular to the axle axis direction, are joined and integrated. The half bodies la and ib are joined and fixed by abutting and joining the joining flanges 5a and 5b extending on the inner periphery of the rim part 2 and both sides of the spoke parts 30, respectively, and joining these joining flanges 5a and 5b with bolts. - Tightened and integrated with mechanical fixing means 6 such as nuts or rivets. The spoke portion 3 has a U-shaped cross section with joining flanges sa+sb on both sides when the half bodies 1a and 1b are joined, but in the joined state of the half bodies ia and 1b, as shown in FIG. As shown in the figure, it becomes a hollow square shape and has strength.
It provides rigidity. Moreover, the hollow corner shape is formed such that it gradually becomes thicker toward the center of the wheel, and the connecting portion I between the spoke portion 3 and the rim portion 2 and the protrusion portion 4 is formed.

ドストッパ１４が形成されている。(3) The fiber-reinforced resin is a material that uses, for example, epoxy resin, polyester resin, phenol resin, etc. as a matrix and is reinforced with filaments such as carbon fiber, aromatic polyamide fiber, glass fiber, silicon carbide fiber, boron fiber, alumina fiber, etc. It consists of The split bodies 1a+11) constituting the wheel body 1 are molded by laminating reinforcing fibers and resin in respective molds, curing them under pressure, and integrally molding them, and then demolding and finishing. Processing is performed to form divided bodies 1a+1b. A bead stopper 14 is formed at a shoulder portion 2C between the bead seam 1 portion 2a and the well portion 2b of the rim portion 2.

強化樹脂等により形成されている。The bead stopper 14 may be formed as a protrusion over the entire circumference of the shoulder portion 2C, or may be formed as protrusions or protrusions at appropriate intervals. (5) (4) The bead stopper 14 is made of synthetic resin, synthetic rubber, fiber-reinforced resin, or the like.

に一体形成してもよい。The bead stopper 14 is integrally joined to the rim portion 2 in the next step after the wheel body 1 is molded. That is, for example, a synthetic resin or a fiber-reinforced resin is set in a simple mold having a cavity that forms the bead stopper 14, and then the rim portion 2 is set thereon and joined and integrated by pressure curing. In addition, when forming the bead stopper 14 with fiber-reinforced resin, it may be integrally formed at the same time as molding the rim part 2.

うにしている。The two halves of the rim portions 2 having the bead stoppers 14 thus formed are joined together by joining the divided bodies 1a and ib as described above. Then, a synthetic resin is applied to the surface of the rim portion 20 to cover the vibrator 14 and the entire surface thereof, thereby forming a synthetic resin coating layer 15 on the rim surface. As a result, the bead stopper 14 portion of the synthetic resin coating layer 15 protrudes, and the surface of the other rim portion 20,
Irregularities and gaps that may exist at the joint of the bead stopper 14 or the joint of the two-piece rim part 2 are closed to ensure a smooth L1 airtightness. The tubeless tire 16 is mounted with its bead portion 16a pressed against the bead seat portion 2a, and the bead portion 16a
The inner side 16b of is locked by the bead stopper 14,
This prevents the bead portion 16a from shifting or falling from the shoulder portion 2C into the inner well portion 2b and coming off the rim portion 2a.

様にビード部の外れを防止するのに有効である。Further, although the above embodiment has been described with respect to the case where a tubeless tire 16 is mounted, the present invention is also effective in preventing the bead portion from coming off in a tube tire as well.

している。In the present invention, as mentioned above, the rim is molded from fiber-reinforced resin, which is a lightweight material, so the weight of the rim can be reduced (7), and since a bead stopper is integrally formed on the surface of this rim, it can be attached to the rim. The bead portion of the tire which has been fixed is locked by the bead stopper and is securely held by the bead seat portion of the rim portion so that it does not shift or come off. Moreover, this bead stopper is integrally joined to the surface of the rim made of fiber reinforced resin, and has the advantage of being easy to mold, reducing the weight of the rim, and improving productivity.
