A soundproof cover is mounted to a first gear box of a power seat motor unit that is attached to a frame member of a seat and that has a motor and a gear box. In the first gear box, the axial direction of the motor is defined as the X direction, the direction of attachment to the frame member, which is one of two directions that are orthogonal to the X direction, is defined as the Y direction, and the remaining direction is defined as the Z direction. Then, the soundproof cover has: a foam disposed on at least an X-Z surface of the first gear box; a cover member disposed on the outer side of the foam; and a mass body interposed between the foam and the cover member and disposed at a position corresponding to at least the X-Z surface of the first gear box in contact with the foam.
