Abstract

A fan includes a casing that includes a first wall portion (56a) having a spiral shape extending along the outer peripheral edge of an impeller (53) and that has a suction port (71) at one end in a direction of a rotational axis of the impeller (53), an air passage (A) extending along an inner surface of the first wall portion (56a) to be in communication with the suction port (71) and in which an airflow moving from one end to another end of the first wall portion (56a) is formed, and a blow-out port (72) at the airflow-downstream end of the air passage (A). Another end of the first wall portion (56a) is at a position obtained by rotating by 360° or more, with the position of a tongue portion (57) formed at one end of the first wall portion (56a) as a starting point, about a rotational axis (O) in a rotational direction of the impeller (53).
