Accordingly, the door 11 (11a, 11b) is driven to move in the opening direction and the closing direction by the rotation of the screw shaft 52 accompanying the forward rotation operation and the reverse rotation operation of the drive motor 51.
  • the opening / closing drive mechanism 60 includes a drive motor 61, screw shafts (62a, 62b), rotation receiving portions (63a, 63b, 63c), gear portions (64a, 64b), nut members ( 65a, 65b) and the like.
  • One end of the screw shaft 62a is connected to the drive motor 61, and the other end is rotatably supported by the rotation receiving portion 63a.
  • the screw shaft 62a is rotationally driven together with the rotation of the drive motor 61.
  • the screw shaft 62b is formed with a screw portion in the same direction as the screw shaft 62a, and both ends thereof are rotatably supported by the rotation receiving portions (63b, 63c).
  • gear of the spur gear was formed in the outer periphery is coaxially fixed to the screw shaft 62a.
  • spur gear teeth are formed on the outer periphery of the screw shaft 62b, and a gear portion 64b meshing with the gear portion 64a is coaxially fixed. Accordingly, when the screw shaft 62a is rotated by the operation of the drive motor 61, the screw shaft 62b is rotated in the opposite direction to the screw shaft 62a through the meshing of the gear portion 64a and the gear portion 64b.
  • the nut member 65a is provided as a member that is screwed to the screw shaft 62b and connected to the door mechanism 14a that supports the door 11a in a suspended state.
  • the nut member 65b is provided as a member that is screwed to the screw shaft 62a and is connected to the door mechanism 14b that supports the door 11b in a suspended state. Accordingly, the door 11 (11a, 11b) is driven to move in the opening direction and the closing direction by the rotation of the screw shaft 62a and the screw shaft 62b accompanying the forward rotation operation and the reverse rotation operation of the drive motor 61. .
  • the present invention provides a door suspension device that supports a door that is provided on a structure and is driven to open and close by an opening and closing drive mechanism in a slidably suspended state with respect to the structure and that is coupled to the opening and closing drive mechanism, and the door
