The work of fixing 5 takes time and effort.

In addition, since the hanging length of the elevating cord 5 fluctuates by the pushing amount of the hanging portion 33 and the pin 39, the elevating cord 5 must be fixed to the hanging length in consideration of the pushing amount. There is a problem that the work of adjusting the hanging length of the lifting cord 5 is troublesome.

[0011] In view of the above problem, the present invention inserts the lifting cord into the insertion groove of the winding part formed on the string fixing device, winds an arbitrary number of turns around the peripheral surface of the winding part, and winds it around the winding part. Since the turned string and the string inserted into the insertion groove are superimposed in an intersecting state, the elevating string can be fixed securely and firmly to the string fixing device and the curtain, and any hanging An object of the present invention is to provide a string fixing device for hanging a curtain body, which can easily and easily adjust the length.
