ABSTRACT:
A speed control apparatus for a continuously variable speed transmission comprises ratio control units for controlling a speed reduction ratio and a manual value for selecting either a running range where engine power is transmitted to the wheels or a neutral range where the engine power is not transmitted to the wheels. The speed reduction ratio is controlled by the ratio control units so as to coincide with a reference speed reduction ratio corresponding to the vehicle speed detected by a speed sensor when the neutral range is selected by manual valve.
