A stator vane (42) has an upstream edge (43) and a downstream edge (45). When the upstream edge is viewed from a direction parallel to a rotational axis (80), an inside portion (P1) of the upstream edge, which is positioned nearest to the rotational axis, is positioned farther forward in the rotational direction of a propeller fan than an outside portion (P2) of the upstream edge, which is positioned farthest from the rotational axis. Viewing the projected image drawn on a plane when the stator vane is projected in a direction parallel to the rotational axis onto a plane perpendicular to the rotational axis, the circumferential length (LA) of a base portion (46) of the stator vane, which is positioned nearest to the rotational axis, is greater than the circumferential length (LB) of an outer peripheral portion (41) of the stator vane, which is positioned farthest from the rotational axis. A fluid-feeding device is obtained with which it is possible to feed out an airflow straight ahead with wind pressure. |
