Claims

[Claims for Utility Model Registration] (1) A gear train disposed between an input shaft and an output shaft that selectively achieves a plurality of forward gears and reverse gears, the gear train sliding in the reverse gear. A shift mechanism for a manual transmission for a vehicle for achieving selection through meshing, comprising a shift select shaft capable of axial movement and rotation around the shaft, and a shift select shaft fixedly supported by the shift select shaft. , a first shift lever having a pawl portion capable of selection movement and shift rotation, and operated to select one gear train by being pushed by the selection movement and shift rotation of the pawl portion of the first shift lever; A plurality of forward and reverse shift fork heads arranged sequentially with the reverse side at one end, and the amount of movement of the shift fork heads other than the shift fork head pushed by the first shift lever are limited to a predetermined amount or less. an interlock plate, which is rotatably supported on the shift select shaft adjacent to the first shift lever, and is configured to move backward when the first shift lever is selectively moved to a position for pushing a backward shift fork head; A second shift lever is provided with a pawl at a position for pushing the forward shift fork head, which is disposed on the other end side opposite to the forward shift fork head. A manual transmission for a vehicle, comprising: an engaging means for integrally coupling the first and second shift levers, and releasing the integral rotation of the first and second shift levers when a predetermined value is exceeded. Shift mechanism. (2) The engaging means includes a recess and a land formed in the second shift lever, a ball that can engage and come into contact with either the recess or the land, and one end of which is connected to the first shift lever and the other end of the ball that can engage and come into contact with either the recess or the land. 2. The shift mechanism for a manual transmission for a vehicle according to claim 1, further comprising elastic members supported by the balls and exerting an elastic force between the first shift lever and the balls.
