Abstract:
To cut an installation space and cost by miniaturizing and simplifying a device and easily adjust an opening and closing speed.
In this device, a door body 15 is rotatably provided on a casing 17, a rotating member 23 rotating together with the door body 15 is adhered to the door body 15, and a slidable contact piece 22 is attached to the casing so as to bring it into slidable contact with the rotating member 23. A magnet is provided on either one of the rotating member 23 or the slidable contact piece 22, the other is made to be magnetic body material and an increase of opening and closing speed of the door body is suppressed by a friction force produced by absorption between the rotating member 23 and the slidable contact piece 22.
