A fan guard 18 of an outdoor unit comprises an outer frame, a plurality of radiating ribs 27, and a plurality of annular ribs 28. The outer frame is disposed around the outer circumference of a lid member that is an air conditioner discharge port. The plurality of radiating ribs 27 are formed such that they radiate in the outer radial direction from the vicinity of the center of the outer frame 26 to the outer frame 26, and are curved in the rotational direction of a ventilation fan. The plurality of annular ribs 28 are integral with the radiating ribs 27, are concentrically disposed at a predetermined spacing in the radial direction around the center of the rotational axis of the ventilation fan, and are formed such that at least those in an outer circumference are slanted toward the outer radial direction to follow the flow of the air blown from the ventilation fan.
