Abstract
A pump device includes an impeller and a housing that houses the impeller in a rotatable manner. The impeller includes a fin (vane) unit and a movable sleeve. The housing includes a fixed sleeve that houses the movable sleeve. A first gap is formed between an inner periphery of the movable sleeve and an opposing surface that faces the inner periphery. Since the inner periphery and the opposing surface are inclined relative to an axis of the impeller, the first gap is increased when the impeller ascends with rotation of the impeller.
