Therefore, the standing wave in the gap between the door panel and the door frame can be suppressed by the fibrous structure to alleviate the resonance transmission, and moreover, the fibrous structure can be formed along the edge of the front side of the door panel. Since it is attached, it is possible to obtain a high effect of preventing standing waves from being generated in the gap between the door panel and the door frame, and it is possible to suppress deterioration of the sound insulation performance in the gap and obtain a high sound insulation effect. There is an advantage that you can. Further, since a recess is provided on at least one of the end surface of the door panel and the inner surface of the door frame and a sound absorbing material is attached to the recess, it is possible to absorb the occurrence of standing waves in the gap between the door panel and the door frame. This can be suppressed by the material, and the sound insulation effect can be further enhanced in combination with the effect of the fibrous structure.
