Abstract
An engine cover has a cover body having a through hole penetrating both sides of the cover body in an area opposed to a resonant space in which resonant sounds are generated. An opening of the through hole is covered with the sound absorbing member layer. Because a part of the resonant space is open, resonant sounds generated in the resonance space are decreased.
