A unit analysis method using "contact model between the element of a belt for continuously variable transmissions and the pulley sheave" and "the model which considered a gap in the bearing" was contrived. And that was made able to predict tooth contact of a gear correctly. In the conventional model, pulley and the neighboring parts was modeled with one body easily. In the new model, slide pulley and fixed pulley were divided, and oil pressure was set,thereby it was able to express pulley axial bending same as an actual machine.
