特徴とする巻き取り装置。[Claims for Utility Model Registration] A fixed shaft portion 1 fixed to a window frame corner corresponding to one of the left and right ends of the upper end edge of the body to be rolled up 19, and a rotating portion by the fixed shaft portion 1. It includes a boss body 6 and a pulley 3 which are freely pivotally connected, a coil spring 9 wound around the fixed shaft part 1 and wrapped inside the boss body 6, and one end 24 of the coil spring 9. It is fixed to a part of the boss body 6, and the other end 1
5 is engaged with the arcuate groove 16 of the pulley 3 with play, and the boss body 6 and the pulley 3 are engaged by a locking mechanism 25 so as to be able to swing relative to each other within a predetermined angle a. When the pulley 3 is forcibly rotated in the winding direction, the boss body 6 is rotationally driven via the locking mechanism 25, and if the pulley 3 is set in a free state without applying any external force, the above Due to the weight of the body 19 to be hoisted, the boss body 6 is moved in the hoisting direction C.
In order to prevent reverse rotation, the coil spring 9 whose one end 24 is fixed to the boss body 6 is compressed, and the coil spring 9 is pressed against the outer peripheral surface of the fixed shaft portion 1 to stop the reverse rotation. When the pulley 3 is forcibly rotated in the lowering direction C, the concave groove 16 of the pulley 3 and the other end 15 of the coil spring 9 are engaged, and the coil spring 9 is rotated in the loosening direction. A winding device characterized in that it is configured to reversely rotate the boss body 6 while releasing the pressure contact d.
