摘要： PROBLEM TO BE SOLVED: To suppress occurrence of tire road noise, to prevent decrease of fuel economy, and to simplify work for attaching a wheel cover. SOLUTION: The wheel cover has a casing forming a cavity 34, and one or more holes 38 for forming a resonance structure at predetermined places of the casing. Since one or more holes 38 for forming the resonance structure are formed, so that the travel of the vehicle can be suppressed from generating tire road noise. A rotary sound absorbing body or the like except for the wheel cover 31 is not required to be mounted to a wheel body, so that the weight of the vehicle does not increase and the fuel economy does not decrease. The work for attaching the wheel cover 31 to the wheel body can be simplified. COPYRIGHT: (C)2005,JPO&NCIPI
