1. A manual transmission (M/T) having no torque converter, which is applied to a vehicle including an internal combustion engine (E/G) and an electric motor (M/G) as power sources, comprising:
an input shaft (Ai) to which power is input from the internal combustion engine; an output shaft (Ao) to which power is input from the electric motor and from which power is output to a drive wheel of the vehicle; a transmission speed change mechanism (M1) configured such that, when a shift operation member (SL) operated by a driver moves, on a shift pattern, to each of hybrid travel shift completion positions corresponding to a plurality of hybrid travel gear stages (2-nd to 5-th) for traveling by using the drive force of the internal combustion engine only of the drive forces of the internal combustion engine and the electric motor, the transmission speed change mechanism establishes a power transmission system between the input shaft and the output shaft such that a transmission speed reduction ratio, which is the ratio of rotational speed of the input shaft to that of the output shaft, is set to a value corresponding to a corresponding hybrid travel gear stage, and when the shift operation member moves, on the shift pattern, to each of motor travel shift completion positions corresponding to a plurality of motor travel gear stages (EV, EV-R) for traveling by using the drive force of the electric motor only of the drive forces of the internal combustion engine and the electric motor, the transmission speed change mechanism establishes no power transmission system between the input shaft and the output shaft, the transmission speed change mechanism including, as the plurality of motor travel gear stages, at least one motor travel gear stage for forward travel and at least one motor travel gear stage for reverse travel; and a connection changeover mechanism (M2) which selectively realizes a connected state in which the output shaft (Am) of the electric motor is connected to the output shaft (Ao) of the transmission in a power transmissible manner and a disconnected state in which the output shaft (Am) of the electric motor is not connected to the output shaft (Ao) of the transmission in a power transmissible manner, wherein the connection changeover mechanism is configured to always realize the connected state when the shift operation member is located at each of the shift completion positions of the motor travel gear stages for forward travel and reverse travel, and to always realize the disconnected state when the shift operation member is located at each of the shift completion positions of the hybrid travel gear stages. |
