Abstract:
1. A transmission comprising: an input shaft for inputting drive force from an engine; an output shaft disposed substantially concentrically with the input shaft so as to be capable of relative rotation with respect to the input shaft; a first layshaft disposed substantially parallel to the input shaft and the output shaft; a speed reduction gear connected between the output shaft and the first layshaft in a constant-mesh manner; and a plurality of transmission gear pairs provided between the input shaft and the first layshaft or output shaft to mutually engage and to transmit the rotational force of the input shaft to the output shaft, wherein said transmission further comprises: an input gear fixedly attached to the input shaft; a second layshaft disposed substantially parallel to the input shaft; a second layshaft gear that engages the input gear and is disposed on the second layshaft; and a braking mechanism for braking the input shaft by braking the second layshaft gear, wherein the second layshaft is a reverse idle shaft fixed to a transmission case, the second layshaft gear is a reverse idle gear disposed rotatably on the reverse idle shaft, and the braking mechanism is provided to the reverse idle gear.
