摘要： A shifting device for a synchromesh-type transmission is designed to detect an accurate change of the input rotation of each area of the shifting operation, and to set the applying load to the shifting fork based on the change of input rotation. The shifting device for a synchromesh-type transmission includes a detecting device for detecting a rotation change rate of an input shaft, a judging device for judging a balk point based on the rotation change rate of the input shaft detected by said detecting device, and a transmission controlling mechanism including an electric-controlled driving device for driving a shift actuator to shift the shift fork. The driving device controls a drive current to the shift actuator when the balk point is detected by the judging device.
