Abstract:
1. A transmission provided with a dual-clutch-type transmission mechanism comprising: a plurality of shift members which are adapted to be moved in a shifting direction and a selecting direction; a plurality of shift lugs each of which has a pair of first claw portions spaced apart from each other in the shifting direction and which are 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 corresponding gear shift operation, wherein the shift members are moved by an actuator so that one of the shift members pushes one of the pair of first claw portions of one of the shift lugs in one shifting direction by inserting the one of the shift members into a space between the pair of first claw portions to thereby selectively move the one of the shift lugs in the one shifting direction so as to cause the shift fork to move from a neutral position to a shift position, wherein while a first one of the shift lugs is held at the shift position, a shift operation of a second one of the shift lugs is performed, and wherein a second claw portion is provided in such a manner as to project from the pair of first claw portions in the selecting direction so that, in the shift position, the second claw portion accommodates a displacement of the one of the shift members in the selecting direction, and the second claw portion is brought into abutment with the one of the shift members in association with a displacement of the one of the shift members from the displacement accommodated state in the shifting direction so as to cause the shift fork to move from the shift position to the neutral position by moving the first one of the shift lugs in a direction opposite to the one shifting direction without inserting the one of the shift members into the space between the pair of first claw portions.
