Title:
WHEEL FOR VEHICLE
Document Type and Number:
Japanese Patent JP3086966
Kind Code:
B2
Abstract:
PURPOSE: To judge various kinds of information on a cast wheel through a process of reading a bar code before a post-treatment work so that the information may be utilized for a corresponding treatment by forming a bar code formed by projections extending over at least one-third the whole periphery of a rim in the circumferential direction on the surface of the rim.
CONSTITUTION: An axle hole 11 is formed in the disc portion 1 of a cast wheel W. A rim portion 2 is integrally formed on the outer peripheral edge of the disc portion 1. In this case, plural projections 3 are formed in parallel in the circumferential direction, on the outer surface of the rim portion 2 extending over at least one third the whole periphery thereof by casting. A bar code is formed by the respective projections 3 to represent various kinds of information (rim system, rim width and the like) on the caset wheel W. On the other hand, various kinds of information are read by a detector not shown to be utilized for a corresponding treatment. The cast wheel W is formed into a designated shape by a lathe in a finishing process, and the projections 3 as a bar code are erased from the final product of a wheel for a vehicle.
