Abstract
Herein disclosed is a motion transforming apparatus, comprising first and second rotation shafts each formed with crank shaft portions, a plate assembly constituted by rotation plates each formed with teeth and cranked through bores respectively having the crank shaft portions of the rotation shafts received therein, a toothed rail having teeth, and a plate assembly housing relatively movable along the toothed rail, wherein the first rotation shaft is driven to rotate the rotation plates, and each of the rotation plates has an untoothed portion connected to the toothed portion of each rotation plate to be spaced from the toothed portion of the toothed rail and to have the toothed portions of the rotation plates closer to the second rotation shaft than the first rotation shaft. The toothed portion of each rotation plate is thus deviated from the second rotation shaft and held in mesh with the toothed rail in the vicinity of the first rotation shaft, thereby reducing a moment which tends to rotate the plate assembly housing around the first rotation shaft so as to lift up the leading end of the plate assembly housing.
