Abstract

A motor includes a bearing having a rolling member disposed between an inner ring and an outer ring, a spring connected to the outer ring, and a pusher connected to the spring and configured to move to a first position spaced apart from the inner ring by the spring. The pusher is further configured to move to a second position at which friction with the inner ring is caused by a pressure of air. The inner ring is spaced apart from the rotating shaft by a gap between the inner ring and the rotating shaft when the pusher is at the second position.
