ABSTRACT:
The second platenary gear mechanism18is a so-called double pinion type planetary gear comprising a sun gear18a, paired pinions18b, a carrier18cwhich supports the pinions, and a ring gear18d. The pinions18bof eeach pair meshes with each other in a state where one of the paired pinions18bmeshes with the sun gear18awhile the other one of the paired pinions18bmeshes with the ring gear18d. The carrier18cis coupled to the countershaft20and the sun gear18ais connected to a shaft11awhich is coupled to a gear11bof a third gear unit11.
