PROBLEM TO BE SOLVED: To provide a soundproof cover capable of reducing noise in a wide frequency range from a high frequency to a lower frequency of a power seat motor unit.SOLUTION: A soundproof cover 3 is mounted on a first gear box 12 of a power seat motor unit 1 fitted to a frame member 2 of a seat and having a motor 10 and a gear box 11. Defining, on the first gear box 12, an axial direction of the motor 10 as an X direction and a direction of fitting to the frame member 2 between two directions orthogonal to the X direction as a Y direction and the remaining direction as a Z direction, the soundproof cover 3 has foam 30 arranged on at least an X-Z plane 121 of the first gear box 12, a cover member 31 arranged outside the foam 30, and a mass 32 interposed between the foam 30 and cover member 31, and arranged at a position, corresponding to at least the X-Z plane 121 of the first gear box 12, in contact with the foam 30.SELECTED DRAWING: Figure 1

    【課題】 パワーシートモータユニットにおける高周波数から低周波数までの広い周波数帯域の騒音を低減することができる防音カバーを提供する。【解決手段】 防音カバー3は、シートのフレーム部材2に取り付けられ、モータ10と、ギアボックス11と、を有するパワーシートモータユニット1の第一ギアボックス12に装着される。第一ギアボックス12において、モータ10の軸方向をX方向、該X方向に直交する二方向のうち、フレーム部材2への取り付け方向をY方向、残りの方向をZ方向と定義した場合、防音カバー3は、第一ギアボックス12の少なくともX−Z面121に配置される発泡体30と、発泡体30の外側に配置されるカバー部材31と、発泡体30とカバー部材31との間に介装され、第一ギアボックス12の少なくともX−Z面121に対応する位置に発泡体30と接触して配置されるマス32と、を有する。【選択図】 図1
