Abstract

The present invention is to provide a transmission mechanism for motion toy comprising a transmission box including a transmission gear set having an input meshed with a driven wheel and an output meshed with at least one idler gear; and a leg assembly including at least one pair of legs each having one end pivotably connected to a point in the idler gear distal from its shaft and the other end pivotably connected to one end of a foot. When the driven wheel is driven by a driver element the transmission mechanism can indirectly drive the idler gear and shift the leg horizontally. In such a manner, a motion toy having a plurality of the transmission mechanisms can walk step by step on a planar surface.
