I and inexpensive production costs and, to facilitate the assembly work. It is supported rotatably on the input end of the (40a) crankpins one particular idle gear for transmitting (61) the cylindrical gear rotation (56) output gear (54) drive motor (70) it is arranged, it is sufficient to support the crank pin (40a) only the idle gear (70), moreover, a cylindrical gear meshing with both the idle gear (70), input gear (60) and (61) axial length is sufficient extent slightly longer than the separation distance end (70), (60) these two gears.
