Abstract
In a supercharger bearing assembly including floating bushes journalling a rotor shaft interposed between the rotor shaft and a housing assembly, the floating bushes each have an inner peripheral portion of a smaller length than an outer peripheral portion, to reduce the amplitude of vibration of the floating bush, reduce the loss of power due to a frictional loss and increase resistance to seizure.
