Abstract (en)
An air-sending device includes: a propeller fan including a shaft located on a rotational axis of the propeller fan and a blade located on a circumferential portion of the shaft; and a fan guard provided leeward of the propeller fan, and including a rib unit in which a plurality of openings are provided to allow air to pass through the openings. The fan guard includes a first region that is located in such a manner as to overlap with the shaft as viewed from a point in a direction parallel to the rotational axis, and a second region that is located outward of the shaft and inward of a rotational trajectory of the blade as viewed from a point in the direction parallel to the rotational axis. Where a dimension of the rib unit in a direction parallel to the rotational axis is a height of the rib unit, a height of part of the rib unit that is located in the first region is smaller than a height of part of the rib unit that is located in the second region.
