A speed change gear for an automatic transmission includes: an input portion; an output portion; and a plurality of planetary gear sets (G1,G2,G3) including a compound planetary gear (G3) set. The plurality of the planetary gear sets has a clutch (C1,C2,C3) and a brake (B1,B2). The clutch includes a first clutch (C1) and a second clutch (C2) for connecting and disconnecting the reduced rotation from a speed reduction planetary gear set (G1) to the compound planetary gear set (G3), and a third clutch (C3) which is a direct clutch for outputting the input rotation at a constant speed to the compound planetary gear set (G3). The third clutch (C3) is disposed radially outward relative to a first ring gear (R1) of the speed reduction planetary gear set. The first ring gear (R1) has an outer periphery which is provided with a clutch hub. The clutch hub constitutes the direct clutch and is an input member to the third clutch (C3). <IMAGE>
