Claims

[Scope of utility model registration request]

The lowering door body is held between a drive shaft that is interlocked and connected to the electric motor side, a take-up shaft that is interlocked and connected to the door body, and a swingable tension member that is biased by a bullet. When the winding shaft comes into contact with an obstacle and stops rotating, the endless body is suspended so that the tension member is swung to the tension side that resists the bullet, and the winding is performed when the electric motor is driven. In an automatic door configured to automatically open and close the door body by forward and reverse rotation of a shaft, the tension member has a structure in which the tension member swings toward the tension side when the door body comes into contact with an obstacle. A detection switch that detects dynamic displacement and makes an emergency stop of the electric motor is installed oppositely so that it swings about a pivot that is common to the swing axis of the tension member, and the detection switch is attached to a fixed member using a magnet. It is magnetically attached and installed so as to be independent of the swinging of the tension member toward the tension side.
On the other hand, a locking means is provided between the detection switch and the tension member, which locks when the tension member swings toward the relaxed side, and causes the detection switch and the tension member to swing together toward the relaxation side against the magnet. An emergency stop device for an automatic door, characterized in that it is provided with an emergency stop device.
