<P>PROBLEM TO BE SOLVED: To provide a multi-stage transmission that can increase the number of change-gear stages while suppressing increase of a shaft length and the number of shafts. <P>SOLUTION: The multi-stage transmission includes: a first input shaft 11; a second input shaft 12; a first friction engagement mechanism C1; a second friction engagement mechanism C2; the first intermediate shaft 31; the second intermediate shaft 32; a first synchronization engagement mechanism SM1; a second synchronization engagement mechanism SM2; a differential mechanism PG; and a third friction engagement mechanism C3. The first intermediate shaft 31 and the second intermediate shaft 32 are connected to a first rotation element Ca and a second rotation element Sa of the differential mechanism PG, respectively. A third rotation element Ri of the differential mechanism PG is connected to an output member 6. A driven gear G1b of a first gear row G1 is pivoted to the output member 6. A third synchronization mechanism SM3 which connects the driven gear G1b of the first gear row G1 to the output member 6, and can transmit power between the first input shaft 11 and the output member 6 by the first gear row G1 is arranged at the output member 6. <P>COPYRIGHT: (C)2012,JPO&INPIT |
