ためである。但し、制振鋼板１２はフレー１１体１０の
内側の全面に設けることを防げない。The structure of this embodiment is such that the vibrations of the face members 13 on both sides are damped by the damping steel plate located between them. Therefore, the damping steel plate 12 is placed in the middle part of the honeycomb structure 11 in the thickness direction. It is arranged parallel to the side members 13 on both sides. The vibration-damping steel plate 12 of this embodiment is arranged not on the entire inner surface of the frame body 10, but in a range where the outer periphery has an appropriate distance from the frame body 10. This is because the portion of the panel near the periphery of the door body has less vibration than the central portion because it is more rigid, and there is less need for damping by the vibration-damping steel plate in this portion. However, the damping steel plate 12 cannot be prevented from being provided on the entire inner surface of the fly 11 body 10.
なお、前記ハニカム構造体１１は面材１３や制振鋼板１
