Abstract
A fan guard of an outdoor unit comprises an outer frame, a plurality of radiating ribs , and a plurality of annular ribs . 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 are formed such that they radiate in the outer radial direction from the vicinity of the center of the outer frame to the outer frame , and are curved in the rotational direction of a ventilation fan. The plurality of annular ribs are integral with the radiating ribs , 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.
