PROBLEM TO BE SOLVED: To provide a wheel cap which can prevent a temperature rise of a brake pad, a disc wheel, and the wheel cap when fitted to the disc wheel. SOLUTION: A wheel cap 1 is removably fitted to a disc wheel 2 and has an air outlet 19 at an outer peripheral edge. The wheel cap 1 has an air inlet 11 formed annularly and a center plate 12 in the center side therefrom. An inside distance A between an innermost wall 111 at the air inlet 11 and a wheel cap center 10 is shorter than a fixation distance D between a hub nut 21 which secures the disc wheel 2 onto an axle hub 33 and a disc wheel center 20.
