ABSTRACT:
An output side transfer member103of a second clutch C-2extends around the outer circumferences of the output side transfer members101, 102of the third and first clutches C-3, C-1, the output side transfer member104(or13, 101) of a fourth clutch C-4and the output side transfer member101of a third clutch C-3are linked to a sun gear S2, the output side transfer member104(or13, 101) of a fourth clutch C-4, an output side transfer member101of a third clutch C-3, and a sun gear S2, which rotate integrally, are disposed radially inward with respect to the output side transfer member102of the first clutch C-1. Thereby, it becomes possible to reduce the diameter of the output side transfer member104(or13, 101) of the fourth clutch C-4, to reduce the weight and inertia, and to improve the controllability of the automatic transmission1.
