It is operated to shift in the direction.

Next, when the electromagnetic coil 622 of the second electromagnetic solenoid 62 constituting the shift actuator 6 is energized from the state shown in FIG. 3, the fixed iron core 623 is excited and the movable iron core 624 is attracted to the fixed iron core 623. As a result, the operating rod 625 attached to the movable iron core 624 moves to the right in FIG. 3, and its tip acts on the other end of the lever 83 (lower end in FIG. 3) to cause the lever 8 to move.
2 is rotated in the direction indicated by arrow 83b in FIG. As a result, the control shaft 37 rotates in the direction indicated by the arrow 37b in FIG. 2 via each member of the second link mechanism 8, and the shift lever 36, which is spline-fitted with the control shaft 37, moves to the second position. It is operated to shift in the direction.

As described above, in the gear shift operating device 2 in the illustrated embodiment, the select actuator mounting portion 43 and the shift actuator mounting portion provided above and below the actuator mounting bracket 4 mounted on the side wall 30 of the transmission case 3. Since the select actuator 5 and the shift actuator 6 are arranged in parallel with each other at 44, the select actuator 5 and the shift actuator 6 can be arranged without laterally projecting to the transmission case 3.
