したことを特徴とするシート巻取装置。[Claims for Utility Model Registration] A casing that is fixed to a supporting member and has a fixed pipe attached therein, a driven shaft and a driving shaft that are inserted into the fixed pipe so as to form a double pipe structure, and the fixed pipe. a coil spring formed into a coil having a diameter larger than the inner diameter and having hook portions at both ends inserted into a slit communicating the driven shaft and the drive shaft; a take-up shaft around which the sheet is wound and the driven shaft; a flexible shaft that connects the driven shaft to transmit rotational force, the coil spring expands in diameter and locks due to the rotational force applied to the driven shaft, and rotation of the drive shaft causes the coil spring to tighten. A sheet winding device characterized in that the diameter of the driven shaft is reduced and the driven shaft rotates to wind up and pull out the sheet via a flexible shaft.
