A branched power transmission whose transmission ratio is continuously variable and that includes two planetary transmissions, each having a sun gear, a planet gear, and a ring gear, and a speed change mechanism having a pair of driven shafts. One gear of the first planetary transmission is non-rotatably connected with an input shaft and provides a rotational connection between the input shaft and the driven shafts of the speed change mechanism. One gear of the second planetary transmission is non-rotatably connected with an output shaft and provides a rotational connection between the output shaft and the driven shafts of the speed change mechanism.
