ターの落下防止装置。 A winding shaft for winding the shutter curtain has an operating arm that is displaced in the outer circumferential direction by obtaining centrifugal force due to abnormal rotation of the winding shaft, and a detection switch that detects displacement of the operating arm in the outer circumferential direction. The brake means applies a brake to the rotation of the winding shaft in response to a detection command from the detection switch, and the braking means is operated in conjunction with the abnormal rotation of the winding shaft to lower the winding shaft. A shutter fall prevention device characterized by regulating rotation.
