PURPOSE:To make it possible to arrange the input shaft and the output shaft, of an actuator for speed change dispersedly so as to contrive to shorten the whole length of a shaft by arranging in parallel two sets of planetary gear mechanisms separately on the input shaft and the output shaft. CONSTITUTION:A planetary gear mechanism Y1 on one side in a Simpson-type planetary gear type speed change mechanism AT, which has a pair of planetary gear mechanisms Y1, Y2, is installed on an input shaft 1. Likewise, a planetary gear mechanism Y2 on the other side is installed on an output shaft 2. Moreover, through two pairs of gear arrays G1, G2 which are formed between the input shaft 1 and the output shaft 2, mutually corresponding gears, in a pair of planetary gear mechanisms Y1, Y2 are connected to each other. By this constitution, it is made possible to shorten the whole length of a shaft. |
