Abstract: A vehicle wheel comprises a rim (172) and a disk section (171) separate from the rim. Since the disk section is separate from the rim, the freedom of designing the disk section is improved. The rim comprises an outer rim (178) and an inner rim (181) separate from the outer rim. The outer and inner rims are attached to the outer periphery of the disk section at the same place by welding.

Abstract: A surface finishing method for aluminum shapes by barrel polishing, wherein caps are mounted at both open ends of a hollow aluminum shape, and two aluminum shapes each mounted with the caps are set on two right and left holders so as not to interfere with each other, the two aluminum shapes held above and below by the two right and left holders are next put in a barrel pot, and water, a compound, and a medium are put in the barrel pot, and then the barrel pot is closed by a lid. A plurality of barrel pots are installed on a centrifugal barreling machine, and the centrifugal barreling machine is operated so that the aluminum shapes are rotated and revolved.

Abstract: A wheel for a vehicle comprises first and second wheel halves joined together, and a center plate being generally cross-shaped. Each wheel half has a disk portion and a rim continuing from the disk portion. The center plate is inter-posed between the disk portions and has a diameter smaller than an outside diameter of each of the disk portions. The first and second wheel halves and the center plate are unitarily connected together by means of a plurality of sockets each having a countersunk head and a cylindrical shank. This arrangement increases freedom of design of the wheel and facilitates production of the same.
