の車両用マニユアル変速機のシフト機構。[Claims for Utility Model Registration] (1) An example of a gear disposed between an input shaft and an output shaft for selectively achieving a plurality of forward gears and a plurality of reverse gears; A shift mechanism for a manual transmission for a vehicle that achieves selection through dynamic meshing includes a shift select shaft that can move in the axial direction and rotate around the shaft, and a shift select shaft that is fixedly supported by the shift select shaft and that selects the shift select shaft. A first shift lever including a pawl portion extending outward in the radial direction of the shaft, and an engaging portion selectively connected to the pawl portion by axial movement and rotation of the first shift lever. , a plurality of forward and backward shift fork heads formed sequentially in the axial direction, rotatably supported on the shift select shaft adjacent to the first shift lever, and the first shift lever and the one end; a second shift lever that engages the forward shift fork head when the side reverse shift fork head is selectively engaged and is formed to extend radially outward; An interlock plate that restricts the rotation of the second shift lever and is unrotatably supported by the case, and allows a predetermined amount of integral rotation of the first and second shift levers, and controls the reverse shift fork head and the forward shift lever. At the same time, when the predetermined amount is exceeded, the rotation of the second shift lever is restricted by the interlock plate, and the second shift lever is returned to its original position, and only the forward shift fork head is activated. A shift mechanism for a manual transmission for a vehicle, comprising: an engagement means for releasing the . (2) The engaging means is located at a portion extending radially outward of the first shift lever, and includes a ball and an elastic member that biases the ball toward the second shift lever. and two recesses that can be engaged with the ball in response to rotation of the first shift lever, in a portion extending outward in the radial direction of the second shift lever corresponding to the lock ball mechanism. 2. The shift mechanism for a manual transmission for a vehicle according to claim 1.
