Although it is immersed in oil in the mission case for lubrication, continuous high-speed rotation may cause oil shortage in the synchronizing member, resulting in severe wear and seizure. Further, since the shifter is synchronously rotated with one of the rotary transmission bodies and meshes with each other, when the shifter is shifted (pushed) to one side, the oil flows too much to the other synchronizing member,
One of the sync members may run out of oil.

I will escape to the side. Therefore, the first radial groove 39 and the hole 44 are circumferentially out of phase with each other as shown in FIG.
The communication passages (holes) 44 of the synchronizing members 41, 42 are circumferentially out of phase with the first and second radial grooves 39, 40.
