The driving element 2 is driven. At the neutral point, the first engagement element 52 and the second engagement element 53
Is pushed by the solenoid 5 and is not fixed by neutral. When the driving element 2 is further advanced, it shifts to the opposing stage.

When the selected a is in the state shown in FIG. 2 during the shift, the unselected b is in the state shown in FIG.

Here, when shifting the shift stage connected to b, the solenoid corresponding to b is energized from just before neutral. When the drive element 2 corresponding to b reaches neutral, the second and third engagement elements 52, 53 corresponding to b are pushed in, and the fork shaft 3 of b
Becomes shiftable. At the same time, the second and third engagement elements 52, 53 corresponding to a are pushed up, and a becomes neutral.

When the driving element 2 corresponding to b is further driven in this state, the inner lever 4 corresponding to b is driven.
And fork shaft 3 of b
Works.
