PROBLEM TO BE SOLVED: To improve the aerodynamic performance without degrading the brake cooling performance in a vehicle wheel structure. SOLUTION: When a vehicle is traveling, the air flow in the external direction of the vehicle is constantly permitted through a through hole 11c1 formed in a connection part 11c for connecting a rim part 11a to a hub part 11b in a wheel part of a wheel 10, and an annular guide surface 21a (a surface on the external side of a ring cover 21) which straightens the air flow and merges it to the air flow along a side wall 12a on the external side of the tire 12 fitted to the rim part 11a is provided on an outer end in the axle direction of the rim part 11a.
