A first carrier (14) rotates integrally with an input shaft (7). A third sun gear (31) and a fourth sun gear (41) rotate integrally with a first intermediate shaft (81). A third carrier (34) rotates integrally with a second ring gear (23). A fourth carrier (44) rotates integrally with a third ring gear (33), and outputs power. A first clutch (51) couples a first ring gear (13) and a second sun gear (21) to the first intermediate shaft (81), A second clutch (52) couples the first carrier (14) to a second carrier (24). A third clutch (53) couples the second carrier (24) to the first intermediate shaft (81). A first brake (61) brakes rotation of a first sun gear (11). A second brake (62) brakes rotation of the second ring gear (23) and the third carrier (34). A third brake (63) brakes rotation of a fourth ring gear (43). |
