Abstract
An oscillating device for a children's swing apparatus includes a base, a driving assembly mounted to the base, a first friction piece connected to the driving assembly, and a second friction piece operably driven by the first friction piece depending on a friction force therebetween. An elastic piece urges against one of the first friction piece and the second friction piece, a first shaft passes through a transmitting assembly, and an output member is operated by one of the first shaft and the second friction piece. The swing apparatus further includes a first frame supported on the ground, a second frame in which the sitting device is mounted such that the oscillating device connects the first frame to the second frame.
