Abstract: Provided is a device having an improved structure that lowers the unit cost and failure rate of a product by reducing the number of components and improves the assemblability, consistency in quality, operational stability, and convenience of future servicing of the product. In the device, a shaft and a shaft coupling part of a winding drum are simply coupled without a separate coupling member as a protruding portion formed on the shaft becomes caught in a catching portion formed on the shaft coupling part.
