REELING DEVICE FOR WINDOW COVERING
A reeling device for a window covering is disclosed, including a base having a perforation, an end cap, and a rotating member engaged to the base. The rotating member is rotatable around an axis, and has a body portion having a first end and a second end. An end of the lifting cord is engaged to the body portion near the first end, while another end passes through the perforation and winds around the second end. The end cap is engaged to the first end and is rotatable, which includes a tapered sleeve and a tubular body fitting around the body portion to cover a cord segment engaged to the body portion; the tapered sleeve is connected to the tubular body, and an outer diameter thereof decreases in a direction away from the first end. Such structure is helpful to control a lifting cord to smoothly operate a shade material.
