摘要： The present disclosure is to reduce a blowing resistance while securing a mechanical strength of a fan guard.
An outdoor unit 100 includes a housing 10 in which an air discharge port X is formed on an upper wall 11, a blowing fan 20 disposed inside the housing 10 to correspond to the air discharge port X, and a fan guard 30 configured to cover the blowing fan 20, wherein the fan guard 30 includes a plurality of annular ribs 32 disposed to be spaced apart from each other in a radial direction of the blowing fan 20, and radial ribs 33 configured to connect a plurality of the annular ribs 32, and wherein the radial ribs 33 are formed such that free ends 3a thereof are bent in the same direction in a cross section orthogonal to a stretching direction and a pair of opposing piece portions 3b including each of the free ends 3a are in surface contact with each other.
