Abstract
An oscillation device of a motion toy includes a variety of moveable shells configured for receiving the oscillation device, a first transmission box, a first link member, and an end arcuate groove near in one of the shells. One or more cams are provided on the first transmission box. Each cam is coupled to a first shaft of the first transmission box so that during a rotation of the cams as activated by the first shaft, another shell is capable of being pushed by one cam. Hence, the cams and the first link member are operative to move together wherein the first link member moves reciprocally in the arcuate groove, thereby enabling an oscillation by the moving first link member to move the another shell.
