ABSTRACT:
A transmission apparatus includes a gear having a plurality of gear teeth and a rack having a plurality of rack teeth to mesh with the gear teeth. The rack further has an end formed as a cantilever beam structure. In an initial contact of the gear teeth with the rack teeth at the cantilever beam structure of the rack, the cantilever beam structure can deflect to buffer an impact resulted from the contact so that the meshing of the gear teeth and the rack teeth can be much smoother and possible collision in between can also be avoided.
