WHEEL FOR VEHICLE

PROBLEM TO BE SOLVED: To provide a wheel for vehicles having greatly improved durability by giving absolute strength to the surface of a nut seat. SOLUTION: A disk 3 made of a cladding material of aluminum and stainless is arranged in the diameter direction of ring-like rim members 1, 2, and the three members are integrated by welding 4. Since the nut seat is made of stainless steel, the surfaces 6a, 6b have absolute strength, thus improving durability greatly. A part 3a made of aluminum in the disk material 3 and the rim members 1, 2 made of aluminum can be fixed by welding, thus also resulting in advantageous manufacture. The disk material 3 itself cannot be thinned, and a wheel in the same shape can be formed in terms of appearance as in the case of a conventional aluminum material. When the surface of the nut seat of a hole 6 for mounting the wheel formed at the disk material 3 is set to be spherical 6a, or an outward expanding inclined shape 6b, a load applied to the wheel is received by a part 3b made of stainless steel in the disk material 3, thus preventing the nut seat from being deformed or locally collapsing even after repeated use.
