PROBLEM TO BE SOLVED: To provide a multistage transmission having shifting operation at seven or more forward stages for meeting requirements of shift ratio property, shift controllability and compactness at a high level. SOLUTION: The multistage transmission comprises a first rotating element RM1 formed by a sun gear S4, a second rotating element RM2 formed by a ring gear R2, a third rotating element RM3 formed by connecting carriers CA2, CA3 to each other, a fourth rotating element RM4 formed by connecting a ring gear R3 and a carrier CA4 to each other, and a fifth rotating element RM5 formed by connecting sun gears S2, S3 and a ring gear R4 to one another. RM1-RM3 are connected to a case 32 via brakes B1-B3, RM5, RM 1 are connected to a ring gear R1 of a first planetary gear device 12 via clutches C1, C2, RM2, RM3 are connected to an input shaft 24 via clutches C3, C4, and RM4 is integrally connected to an output gear 26. Eight forward stages are established in accordance with an operation table shown in (b). COPYRIGHT: (C)2005,JPO&NCIPI
