Abstract:
1. An automated manual transmission for a vehicle, comprising: an input shaft configured to receive rotating force from a power source; an output shaft disposed parallel to the input shaft so that power is output from the output shaft; and a plurality of shift gear trains each comprising external gears respectively provided on the input shaft and the output shaft in such a way that the external gears circumscribe each other, the external gears forming a pair that embodies one of a series of shift ratios, wherein among the external gears that form a shift gear train in the plurality of the shift gear trains that embodies at least two adjacent shift ratios, either of two external gears that forms each of the shift gear trains is connected to the input shaft or the output shaft by a planetary gear device, wherein two external gears form one shift ratio, one of the two external gears is connected to the planetary gear device, and the other of the external gears is directly connected to either the input shaft or the output shaft, which is not equipped with the planetary gear device.
