摘要： A belt type continuously variable transmission is provided with two pulley shafts (51,61) arranged in parallel a predetermined distance apart from each other, a movable sheave (53) on each pulley shaft, the movable sheaves (53,63) being able to slide in an axial direction on the pulley shafts a fixed sheave (52) arranged on each pulley shaft so as to face the moveable sheave (3) on each pulley shaft the fixed sheave and the movable sheave that face each another on each pulley shaft together forming a groove (80a) therebetween, and a belt wound around the grooves between the moveable sheaves and the fixed sheaves that face one another. At least one of the movable sheaves and a motor (550) serving as a driving source for the moving sheave are integrally provided.
