Title:
WHEEL DISK
Document Type and Number:
WIPO Patent Application WO/2023/149502
Kind Code:
A1
Abstract:
The present invention achieves a further reduction in the weight of a vehicular wheel disk 1. A hat part 20 of the vehicular wheel disk 1 has: an annular top section 21; an inner peripheral section 22 which connects the top section 21 and a hub attachment section 10; and an outer peripheral section 23 which connects the top section 21 to welding flanges 30 and window-forming flanges 40. Each welding flange 30 is welded to the inner periphery of a wheel rim 2, and a window 5 is formed between each window-forming flange 40 and the inner periphery of the wheel rim 2. The outer peripheral section 23 of the hat part 20 has first regions 231, which are contiguous with the welding flange, and second regions 232, which are contiguous with the window-forming flange 40, alternatingly arranged in the circumferential direction. A connection section 45 between a second region 232 and a window-forming flange 40 protrudes further axially outward than a corresponding site 231a which is separated from the wheel center axis line L in the first region 231 by the same distance.
