PURPOSE:To efficiently reduce propagation of vibration and vibration noise. CONSTITUTION:In an automatic door of which a rail member 3 and a driving device 5 are supported by bases 6, 6a, 6b in a transom 2 above an opening of a building, the driving device 5 is elastically supported on the base 6a via cushioning materials 7, 8 such as vibration control rubbers equipped in the direction of receiving a compressive load and an angle material 15. The rail member 3 is elastically supported on the base 6b via other cushioning materials 9, 10, 11 such as vibration control rubbers equipped in the direction of receiving the compressive load and a support member 16, thus providing vibration control. |
