Claims

[Scope of utility model registration request]

A plurality of shift forks are provided in the fork shaft so as to freely slide, a shift actuator is provided to move the fork shaft in the axial direction, and a selection actuator is provided in the transmission cover corresponding to each shift fork. , each of the shift forks is provided with an engager that restrains the shift fork to either the shift shaft or the transmission cover as the select actuator expands or contracts in the neutral position, and the engager is moved in the direction of contraction of the select actuator. In addition to providing a biasing spring, when one of the select actuators is in an extended state, the locking ball pushed out of the recess of the push rod pushes the locking ball of the other select actuator into the recess of the push rod to activate these operations. In a gear shift device for a multi-speed transmission equipped with a locking interlock mechanism, each select actuator is provided with a select non-set detection means that operates at a stroke position where the locking ball can be pushed into a recess in the push rod, and the select actuator is extended when changing gears. A gear shift device for a multi-gear transmission, characterized in that the gear shift device for a multi-gear transmission is provided with a control means for extending the next select actuator when the select actuator in the current state is contracted and its select non-set detecting means is activated.
