PROBLEM TO BE SOLVED: To provide a wheel for a vehicle having a cast hole part structure capable of achieving compatibility of lightweight, torsional rigidity and rotary bending rigidity with one another. SOLUTION: This wheel 1 for the vehicle is furnished with disc parts 4 having spoke parts 2 and window parts 3 formed between the spoke parts 2, rim parts 5 and hub fixing parts 6. A cast hole part 7 extends to the hub fixing part 6 on the back surface side of the spoke part 2, a window rib 8 is formed between the thinned part 7 and the window part 3, and the maximum width W<SB>1</SB>of the cast hole part at the hub fixing part 6 is larger than the width W<SB>2</SB>of the cast hole part 7 at an inner peripheral part of the spoke part.
