Patent ID: 7237638

Claim:
A V-belt continuously variable transmission apparatus, comprising: a driving pulley driven by an engine; a driven pulley being driven by said driving pulley through a V-belt, wherein each of said pulleys includes a fixed part fixed to a support shaft therefore, and a movable part provided for sliding movement in an axial direction with respect to said support shaft, said movable part of said driving pulley being displaced in the axial direction by a motor to vary the distance between said fixed part and said movable part, and said movable part of said driven pulley being slidably moved in response to the variation of the distance thereby to vary a speed of rotation of said driven pulley with respect to said driving pulley; a gear system for transmitting power of said motor to said movable part of said driving pulley; and an actuator cover coupled to a front portion of a power transmission case for covering said gear system, wherein said motor is supported on said actuator cover; said power transmission case being adapted to accommodate said driving pulley, said driven pulley, and said gear system therein, and wherein a power transmission case cover is coupled to said power transmission case for covering said driving pulley and said driven pulley, wherein said actuator cover and said power transmission case cooperatively form a wall face of a water pump for circulating water to said engine.
