ABSTRACT:
The selecting actuator 16 is an operating member being capable of shifting a selecting lever by way of a neutral position. The shifting actuator 15 is an operating member being capable of shifting a shifting fork by way of the selecting lever 30. A flow controlling means 12 drives the selecting actuator 16 by a controlling hydraulic flow introduced from the hydraulic pressure source. Hydraulic pressure generating means 10,12 supply a hydraulic fluid discharged from the hydraulic pressure source into hydraulic chambers 15A,15B respectively, thereby carrying out a double action of the shifting actuator 15. A high hydraulic pressure is not supplied to the hydraulic chambers 15A,15B.
