Abstract:
1. A transmission provided with a dual-clutch-type transmission mechanism comprising: a shift member which is adapted to be moved in a shifting direction and a selecting direction; a plurality of shift lugs each of which has a pair of claw portions spaced apart each other in the shifting direction, the shift lugs arranged in the selecting direction; and a shift fork which is connected to one of the shift lugs via a shift rail and performs a gear shift operation, wherein the shift member is moved by an actuator to push one of the pair of claw portions in one shifting direction to thereby selectively move the one of the shift lugs in the one shifting direction so as to cause the shift fork to perform the gear shift operation via the shift rail, and while first one of the shift lugs is held at a shift position, a gear shift operation of second one of the shift lugs is performed, the transmission characterized in that; the pair of claw portions are disposed so as to be offset from each other with an offset quantity larger than a width of the shift member in the selecting direction so as to make the shift member movable in a direction opposite to the one shifting direction while the first one of the shift lugs is held at the shift position after the shift member pushes the first one of the shift lugs in the one shifting direction.
