Abstract:
1. A transmission provided with a dual-clutch-type transmission mechanism, comprising: a plurality of shift members which are adapted to be moved integrally in a shifting direction and a selecting direction; a plurality of shift lugs which are arranged in the selecting direction, each of the shift lugs having a pair of claw portions spaced apart from each other in the shifting direction; and a shift fork which is connected to one of the shift lugs via a shift rail and performs a gear shift operations, wherein the shift members are moved by an actuator so that one of the shift members pushes one of the pair of claw portions of one of the shift lugs in the shifting direction to thereby selectively move the one of the shift lugs in the 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, wherein while one of the shift members is inserted into a space between the pair of claw portions, to make the shift members moveable in the selecting direction without interfering with the shift lugs, the other of the shift members is disposed as to be offset relative to the one of the shift members in the shifting direction such that the other of the shift members is positioned at a retracting position outside the pair of claw portions in the shifting direction.
