Manual transmission

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 (Ac) to which power is input from the electric motor and from which power is output to a drive wheel of the vehicle;
• and
• a transmission speed change mechanism (M) 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 in a state in which drive forces of both of the internal combustion engine and the electric motor can be used, 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, the transmission speed change mechanism establishes no power transmission system between the input shaft and the output shaft,
• wherein the transmission speed change mechanism includes, as the plurality of motor travel gear stages, one motor travel gear stage for forward travel and one motor travel gear stage for reverse travel,
• wherein the shift pattern includes:
• a single selection line extending in a left-right direction of the vehicle which is a path along which the shift operation member moves in the left-right direction of the vehicle as a result of a selection operation, which is an operation of the shift operation member in the left-right direction of the vehicle, in a neutral state in which no power transmission system is established between the input shaft and the output shaft;
• and
• a plurality of shift lines each of which is a path along which the shift operation member moves in a front-rear direction of the vehicle as a result of a shift operation, which is an operation of the shift operation member in the front-rear direction of the vehicle, from a corresponding one of a plurality of selection positions on the selection line, each shift line extending from the corresponding selection position toward one side or both sides with respect to the front-rear direction of the vehicle, and a corresponding shift completion position being disposed at each end of each shift line, and
• wherein the selection position corresponding to the motor travel gear stage for forward travel (EV) is a first selection position which is located at the leftmost side of the vehicle among the plurality of selection positions, and the shift completion position of the motor travel gear stage for forward travel is disposed at a forward end of a first shift line, of the plurality of shift lines, which extends from the first selection position in the front-rear direction of the vehicle;
• and
• the selection position corresponding to the motor travel gear stage for reverse travel (EV-R) is a second selection position which is located at the rightmost side of the vehicle among the plurality of selection positions, and the shift completion position of the motor travel gear stage for reverse travel is disposed at a rearward end of a second shift line, of the plurality of shift lines, which extends from the second selection position in the front-rear direction of the vehicle.
