A speed-change control valve is provided to control an oil pressure to be supplied to the power train. A speed ratio sensor is provided to be moved in mechanical relation to a part of the power train in accordance with a change in the speed ratio of the power train. A linking member is provided to link the actuator, the speed-change control valve and the speed ratio sensor. Additionally, an oil bath is provided to contain oil in which at least a part of the solenoid section of the actuator is immersed.
