装置。The actuating body is inserted into the stationary hoisting shaft, and the actuating piece protrudes from the gap between the coils of the buffer spring that rotates together with the hoisting wheel.It is operated by fitting into the regulating pin provided on the hoisting shaft side. A guide long groove is provided to guide and move the body only in the axial direction of the hoisting shaft, and the operating body, which moves in the axial direction in conjunction with the upwinding movement of the hoisting wheel, is provided at the free end of the buffer spring. The configuration is such that the collision of the actuating piece during the winding movement to the locking portion provided torsionally drives the buffer spring to relieve the hoisting force of the hoisting spring, and the actuating body is connected to the guide groove. One end is left open, and when the shutter is fully closed, the actuator is forcibly moved beyond the position of the actuator in the axial direction to be released from the regulating pin, thereby making it possible to adjust the rotation around the axial center.
