PURPOSE:To improve sound absorption effect by sticking sound absorbing materials, allowing them to face to each other, on the internal wall surfaces facing to each other at substantially symmetrical positions while holding a sound source such as an engine and accessories, etc., therebetween. CONSTITUTION:A hood insulator 2 is stuck on the internal surface of a hood panel 1. Further, thin sound absorbing sheets 20, 21 each comprising felt, non- woven cloth made of glass fiber, etc., are provided facing to each other on the internal surfaces of a wheel house part 10 and a hood ridge 11 located on both side parts of an engine while putting the engine 5 therebetween. Hereby, it is possible to improve sound insulation effect. |
