 note = {application/pdf, The novel mechanism CVT (Shaft Drive CVT, S-CVT) was developed by the authors. The improvement of the power to weight ratio, namely the increase of transmitted power with downsizing and lightening of the transmission is important applying the S-CVT to automobiles. To achieve this objective, the zero-spin disk/roller was devised. By using this disk/roller, the spin decreased to less than 0.9% and the contact pressure also decreased domparing with the ordinary concave one. In this report, the effect of the zero-spin disk/roller was confirmed by the calculation and the experiment. The efficiency of the zero-spin disk/roller was calculated by considering the power transmission of the backup roller based on the traction curve. The calculated efficiency and speed efficiency were 87.7 to 92.7% and 99.0 to 99.4%, respectively. These efficiencies were measured by the experiment using the prototype S-CVT equipped with the zero-spin disk/roller. The results of 79.6% to 95.2% and 99.0 to 99.1%, respectively, were in agreement with the calculated results.},
