ABSTRACT:
In a gear shift mechanism for a manual transmission, a shift rod is axially moved by a driver's manual input force, and this movement is transmitted to a shifter member for shifting a sliding member in a gear train. The shifter member is a swingable lever having a perforation in which a movable member is received. The movable member is movable in and out of its interlocking position in which the movable member partly projects out of the perforation and engages with a recess formed in the side of the shift rod so that the shifter lever and the shift rod are interlocked. When the movable member is out of its interlocking position, the shift rod can freely move without moving the shifter member, so that the shifter member need not move from end to end of the full stroke of the shift rod. In another embodiment, the shifter member comprises a shifter lever and a bell crank.
