Abstract

The second platenary gear mechanism 18 is a so-called double pinion type planetary gear comprising a sun gear 18a, paired pinions 18b, a carrier 18c which supports the pinions, and a ring gear 18d. The pinions 18b of eeach pair meshes with each other in a state where one of the paired pinions 18b meshes with the sun gear 18a while the other one of the paired pinions 18b meshes with the ring gear 18d. The carrier 18c is coupled to the countershaft 20 and the sun gear 18a is connected to a shaft 11a which is coupled to a gear 11b of a third gear unit 11.
