PROBLEM TO BE SOLVED: To achive a plurality of speed-change stages without enlarging a transmission. SOLUTION: This transmission 10 has a planetary gear train G3 having a sun gear S3 connected to an input shaft 11, a planetary gear train G2 having a carrier C2 connected to an output shaft 12, and a planetary gear train G1 having a sun gear S1 fixed to a case 13, and connects a carrier C1 and a ring gear R2, and connects the carrier C2 and a ring gear R3. A clutch A is arranged between a ring gear R1 and a sun gear S3, and a clutch B is arranged between the ring gear R1 and a carrier C3, and a clutch C is arranged between a sun gear S2 and the sun gear S3, and a clutch D is arranged between the sun gear S2 and the carrier C3, and a brake E is arranged between the sun gear S2 and the case 13, and a brake F is arranged between the ring gear R2 and the case 13. Thereby, the transmission 10 can be multi-staged without enlarging it. COPYRIGHT: (C)2010,JPO&INPIT
