To provide a power unit cover capable of achieving high acoustic insulation while suppressing an increase in thickness thereof.SOLUTION: A power unit cover 1 includes: a cover member 2 having a cover body 4 covering a power unit which is a drive source of a vehicle from at least one side of the vehicle in the vertical direction and a plurality of ribs 5 projecting toward the power unit side from the cover body 4; and a sound absorption member 3 arranged in between the power unit and the cover member 2 and formed with recessed parts 31 at positions corresponding to the ribs 5. The rib 5 is made to abut onto a bottom face 34 of the recessed part 31. A height dimension H2 of the rib 5 is formed to be larger than a depth dimension H1 of the recessed part 31. A space S is provided in between the sound absorption member 3 and the cover member 2 in between the plurality of ribs 5.SELECTED DRAWING: Figure 7
【課題】厚みを抑制しつつ、遮音性を向上したパワーユニットカバーを提供する。【解決手段】パワーユニットカバー1は、車両の駆動源であるパワーユニットを前記車両の上下方向の少なくとも一方から覆うカバー本体4と、カバー本体4からパワーユニット側へ突出する複数のリブ5と、を有するカバー部材2と、パワーユニットとカバー部材2との間に配置され、リブ5と対応する位置に凹部31が形成された吸音部材3と、を備える。リブ5は、凹部31の底面34に当接し、リブ5の高さ寸法H2は、凹部31の深さ寸法H1よりも大きく形成され、複数のリブ5同士の間において、吸音部材3とカバー部材2との間には隙間Sが設けられている。【選択図】図7
