Zusammenfassung:An axial gap between an annular projection of a rotor hub of a rotary unit and a sliding seal is set to be smaller than an axial gap between an axially upper face of a shaft and a cover of the rotor hub and an axially gap between an axially lower end face of a sleeve and an axially upper face of a radially-extending part of a bush. Thus, only the annular projection and the sliding seal come into contact with each other, even if the rotary unit moves downward in the axial direction.
