Claims

[Scope of utility model registration request]

The spring case is attached to a fixing bracket that supports the motor and is fixed to a vertical frame, etc., so that it can slide freely in the axial direction without rotating, and is biased upward by a spring. The transmission fitting has an engaging protrusion on the upper end thereof so that the driving gear can be rotated, and a notch cut in the skirt portion engages with the above-mentioned engaging protrusion to rotatably support the transmission metal fitting. Then, the spring case is fitted so as to be pulled down and fitted onto the motor shaft so as to be non-rotatable and slidable in the axial direction. A lever for lowering the transmission fitting is attached so that it can freely engage and disengage the gear of the shaft, and a coil spring is mounted on the inner cylinder of the spring case, and each end of the coil spring is connected to the notch of the drive gear. Between the engagement protrusions of the transmission fitting,
An emergency release device for a blind, etc., in which springs are engaged so as to be movable in the directions of contracting and expanding the diameter by forward and reverse rotation.
