PURPOSE:To restrain efficiently the resonance of an air shroud based upon engine vibration by fixing the air shroud to a crank case through an elastic body for preventing vibration. CONSTITUTION:An elastic body 34 for preventing vibration is interposed between an air shroud 29 and a crank case 6 and supported to be prevented from vibration. And before transmitted to the air shroud 29, the engine 5 side vibration is absorbed and reduced by the elastic body 34 for preventing vibration. Thus, since the engine 5 vibration transmitted to the air shroud 29 is substantially reduced, the resonance of air shroud 29 can be efficiently restrained and noises can be restrained low by the reduction of vibration. |
