Abstract
In a power transmission device, a tapered inner circumferential surfaceincreasing its diameter toward a rotating shaft bodyis formed in a hub, and a tapered outer circumferential surfaceincreasing its diameter toward the rotating shaft bodyis formed in a tubular memberand press-fitted to the tapered inner circumferential surface of the hubso that, when an excessive load is applied between a rotating bodyand a pulley, the hubrotates with respect to the rotating shaftand the tubular memberis withdrawn from the tapered inner circumferential surfaceof the huband power transmission between the rotating shaftand the pulleyis interrupted. Therefore, variation of working torque can be reduced.
