である。The present invention solves the above-mentioned problems, and includes a corrosion-resistant member made of a metal having a higher electrode potential than the metal forming the disk wheel and a lower electrode potential than the metal forming the hub. By placing the disc wheel and the hub in close contact with each other over the entire outer periphery of the hub, the difference in electrode potential that can be a problem in one local cell action can be reduced by reducing the high electrode potential difference between the disc wheel and the hub. , the difference in low electrode potential between the anti-corrosion member and the hub is used to prevent corrosion of the portion of the disc wheel attached to the plate as much as possible even in the presence of water droplets due to local battery action.

。Next, the operation of the above structure will be explained. First, the wheel 1, on which the ring-shaped anticorrosion member 9 is mounted, is attached to the hub 2) via bolts 3 and nuts 6, which are fixing means. After seven months, the anti-corrosion member 9 comes into close contact with the hub 2, and the outermost periphery of the contact portion 7 comes into contact with the outside air.

る。7, for example, splashing of water droplets from the brake disc lO (see diagram #!1) etc. may cause damage to the contact area between the anti-corrosion member 9 and the wheel 1 or the contact area between the anti-corrosion member 9 and the hub 2. Even if water droplets etc. become waxy, the difference in electrode potential at that part is lower than the high electrode potential difference between the wheel 1 and the hub 2 when the anti-corrosion member 9 is not attached to the wheel 1, so the local battery circuit Corrosion caused by formation will be suppressed as much as possible.

口くくなる。Furthermore, the anti-corrosion member 9 has the same surface along the entire outer circumference of the contact portion 7 between the wheel l and the hub 2, and has the same surface from the wheel 1 surface on the upper side in Figure 2 to the hub 2 surface on the lower side in Figure 2. Since the area is continuous with a smooth curved surface, water droplets, etc., do not stay in that area and flow away smoothly (see Figure 2).Therefore, a local battery circuit is formed and becomes blocked.
