Abrégé

An output side transfer member 103 of a second clutch C-2 is linked to a carrier CR2 through the outer circumferential side of the output side transfer members 101, 102 of the third and first clutches C-3, C-1, the output side transfer member 104 (or 13, 101) of a fourth clutch C-4 and the output side transfer member 101 of a third clutch C-3 are linked to a sun gear S2, the output side transfer member 104 (or 13, 101) of a fourth clutch C-4, an output side transfer member 101 of a third clutch C-3, and a sun gear S2, which rotate integrally, are disposed on the inner circumferential side with respect to the output side transfer member 102 of the first clutch C-1. Thereby, it becomes possible to reduce the diameter of the output side transfer member 104 (or 13, 101) of the fourth clutch C-4, it is possible to reduce the weight, the inertia can be reduced, and it is possible to improve the controllability of an automatic transmission 1 for a vehicle.
