ABSTRACT:
A power supplying member supplies rotational power in a certain rotational direction to an input member of the transmission, and a power receiving member takes out power from a driven gear wheel shaft. Two driving gear wheels shafts extend parallel to the driven gear wheel shaft. First and second pairs of gear wheels and first and second synchromesh devices are provided, one of each pair of gear wheels being mounted on the corresponding one of the driving gear wheel shafts and the other being mounted on the driven gear wheel shaft, and one of each pair of gear wheels being rotatably mounted on its gear wheel shaft and being selectively engaged thereto by the corresponding one of the synchromesh devices, while the other one of that pair of gear wheels is fixedly mounted on its gear wheel shaft. First and second clutching mechanisms, each of which either can be disconnected so as to freewheel in both rotational directions or can be connected in the one rotational direction which is required for transmission of power through that clutching mechanism from the power supplying member rotating in the certain rotational direction so as to function as a one-way clutch, are mounted to selectively transmit rotational power between the input member and the first and second driving gear wheel shafts respectively, both proximate to ends of the first and second driving gear wheel shafts that are closest to the input member.
