機の同期装置。A fork shaft double engagement prevention member is provided, and an engagement gap between the member and one fork shaft of the forward stage is formed to be larger than an engagement gap between the member and the fork shaft of the other forward stage, A slidable pin is provided on the one fork shaft, and when shifting to reverse, the pin interferes with the cam of the shift and select lever to operate the fork shaft of the forward gear, and the input shaft is controlled by the synchronizer of the forward gear. Synchronized with the rotation of the output shaft, the double engagement prevention member is returned by a select return spring until it comes into contact with the fork shaft after the reverse shift is completed, so that the engagement gap is not provided to the fork shaft of the forward stage. A synchronizing device for vehicle transmissions.
