Document Type and Number:
Japanese Patent JP2009214880
Kind Code:
A
Abstract:

To eliminate a preparatory process for forming a hollow section and facilitate manufacture of a wheel, in a method of manufacturing a vehicular wheel made of a light alloy and having an annular hollow section on an outer rim.

The manufacturing method is provided for manufacturing the integral vehicular wheel made of the light alloy and having a center disc, the outer rim 23, and in inner rim. According to the manufacturing method, a slope 26 rising radially from a rim well 28 is formed, and a junction portion 33 which is equal in a circumferential diameter is formed on the slope 26 and the outer rim 23. An annular reinforcing plate 25' is joined to the junction portion 33 formed on the slope 26 and the outer rim 23 to form a bead sheet portion 25, thereby forming an annular hollow section 32 in the inside of the sheet portion 25.
