Abstract
A safety device for roller shade bead chain includes a connecting seat, a rotary disc disposed atop the connecting seat and provided along a circumferential face with a plurality of retaining recesses, an elastic element located between the connecting seat and the rotary disc, and a cover plate assembled to the connecting seat to restrict the rotary disc and the elastic element to the connecting seat. A bead chain for controlling a roller shade can be wound around the rotary disc, and then pulled into a straight state before the connecting seat is fixed to a predetermined position. The bead chain being pulled straight and held in place via the safety device will not swing freely to dangerously entangle with and strangulate a child, and is therefore safer for use.
