ABSTRACT:
A belt type steplessly variable transmission includes a belt-pulley device of variable speed ratio and a fluid pressure operated actuator for changing the speed ratio of the belt-pulley device. A fluid control valve is provided for controlling a supply of fluid pressure to the actuator to thereby determine the speed ratio of the belt-pulley device. The fluid control valve is associated including with a manually operable member movable between a first position in which it does not affect operation of the fluid control valve and a second position in which the supply of fluid pressure is changed so that a change in the speed ratio does not take place until input speed to the belt-pulley device exceeds a predetermined value. A manually operable valve is provided for changing the supply of fluid pressure so that the speed ratio of the belt-pulley means is increased.
