To provide a sound insulation structure of a power train which enables effective discharge of water entering into a cover member covering an internal combustion engine.SOLUTION: A sound insulation structure of a power train according to the present invention includes: a cover member 40 which covers at least an internal combustion engine 10 of the power train including the internal combustion engine 10 and has an accumulation part (a bottom surface part 40a) in which water entering into its inner side accumulates; and a water absorption member 42 disposed at the inner side of the cover member 40. The cover member 40 includes moisture release ports 44, 46 for discharging moisture at the inner side of the cover member 40 into atmospheric air. The water absorption member 42 extends from the accumulation part to the moisture release ports 44, 46.SELECTED DRAWING: Figure 2

    【課題】内燃機関を覆うカバー部材の内部に浸入した水を効果的に排出できるようにしたパワートレーンの遮音構造を提供する。【解決手段】本発明に係るパワートレーンの遮音構造は、内燃機関10を含むパワートレーンのうちの少なくとも内燃機関10を覆い、かつ、内側に浸入した水が溜まる溜まり部(底面部40a)を有するカバー部材40と、カバー部材40の内側に配置された吸水部材42と、を備える。カバー部材40は、当該カバー部材40の内側の水分を大気中に放出する放湿口44、46を含む。吸水部材42は、溜まり部から放湿口44、46にまで延在している。【選択図】図2
