<P>PROBLEM TO BE SOLVED: To provide a multistage transmission which can attain the high gear ratio, while providing the balanced gear ratio. <P>SOLUTION: The multistage transmission 10 includes a first shift part 28 having a second planetary gear device 20 for transmitting rotation of an input shaft 16 by reducing a speed and a second shift part 30 for constituting a plurality of rotation elements by mutually connecting a part of the respective elements of two post-installation planetary gear devices 22 and 24. The first shift part 28 also includes an input element (CA1) for inputting the rotation of the input shaft 16 still in its speed, an output element (R1) connected to a specific rotation element RES selectively connected with an output element (R2) of the second planetary gear device 20 in the second shift part 30 and a fixed element (S1) connected to a case 12, and includes a first planetary gear device 18 which can switch a shift state of transmitting the rotation of the input shaft 16 to the specific rotation element RES by shifting and an idle rotation state. <P>COPYRIGHT: (C)2012,JPO&INPIT |
