PROBLEM TO BE SOLVED: To enable protection against the cracking of a splash guard and the entry of muddy water or the like into a hub bearing, in a wheel provided with a service brake unit and parking brake which are separate and independent from each other. SOLUTION: The splash guards 21 and 24 are provided with two notches 21S, 21P, 24S, and 24P corresponding to the service brake unit 2 and parking brake unit 20 on the outer peripheral side, and have splash guards 21A and 24A for the hub bearing which protects the hub bearing 18 from the entry of external foreign matter, and splash guards 21B and 24B for the brakes which protects the brake units 2 and 20 and a disk rotor 5 from the entry of external foreign matter. The splash guards 21A and 24A for the hub bearing and splash guards 21B and 24B for the brake have an expanded part 21i and 24j, which projects in the axial direction of the disk rotor 5 with respect to parts in their outer and inner peripheral positions, on the halfway position in their radial directions.
