PROBLEM TO BE SOLVED: To improve an ornamental hole reinforcing structure of a disc for a two-piece type vehicle wheel.SOLUTION: A two-piece type vehicle wheel 1 comprises a disc 10 and rim 20 which are obtained by molding steel plates. The disc 10 has a hub attachment part 11, a peripheral fixed part 15 fixed to the rim 20, and a plurality of ornamental holes 14a which are formed between the hub attachment part 11 and the peripheral fixed part 15 with intervals in the circumferential direction. Reinforcing parts 30 are formed at peripheries of the ornamental holes 14a. Each reinforcing part 30 has a first wall 31 which is erected so as to protrude from a design face 10a of the disc 10, a folded part 33 continuous to the first wall 31, and a second wall 32 which extends to a direction reverse to a protruding direction of the first wall 31 from the folded part 33. The second wall 32 is located by being shifted to a center side of the ornamental hole 14a with respect to the first wall 31, and arranged so as to oppose the first wall 31. |
