PURPOSE:To prevent slippage due to sudden change in load and improve power transmission efficiency by making the power transmission between input and output disks and a planetary cone a meshed and forced type. CONSTITUTION:Power transmission is carried out between the outside face of an input disk 3 and the outer peripheral surface of the lower cylindrical part 5c of a planetary cone 5 through a bevel gear 9. Equally power transmission is carried out between the outside face of an output disk 4 and the back face part 5d of the planetary cone 5 through a crown gear or a bevel gear 10. By this structure, power from the input disk 3 is securely transmitted to the output disk 4 through the planetary cone 5, without causing slippage even at the time of sudden change in load unlike the conventional pressure contact method. Accordingly, accurate speed setting can be performed, improving power transmission efficiency while preventing rise in oil temperature.
