ABSTRACT:
A continuously variable transmission employing a vane pump and a vane motor has a mechanism for mutually moving housings of the vane pump and the vane motor or for moving each independently. The mechanism can gradually decrease the eccentricity of the internal circumference of the housing of the vane pump with respect to a rotor of the vane pump while increasing the eccentricity of the internal circumference of the housing of the vane motor with respect to a rotor of the vane motor, or vice versa, thereby regulating the rotative speed output from the vane motor.
