ABSTRACT:
A rotary drum assembly is arranged so that upper and lower drums can rotate about a central shaft with respect to each other via a dynamic-pressure bearing. In the rotary drum assembly, the central shaft is press-fitted into the rotary upper drum, a sleeve which is formed so that the central shaft can be rotatably fitted thereinto is supported by the fixed lower drum, and a dynamic-pressure generating groove is formed in either one of the central shaft and the sleeve, whereby a dynamic-pressure bearing is formed between the central shaft and the sleeve.
