Engine cover |
摘要 |
An engine cover has such a structure that a cover body has a through hole penetrating both sides of the cover body in an area opposed to a resonant space in which resonant sounds are generated, and an opening of the through hole is covered with the sound absorbing member layer. Because a part of the resonant space is made open, the resonant sounds generated in the resonance space will be decreased.
