The present invention is aimed to provide a working machine provided with: a condenser unit including a condenser of an air conditioner and a cooling fan for cooling the condenser, the condenser unit being disposed in a side of a cabin; and a protection cover covering above the condenser unit, capable of reducing propagation to an operator side of an air intake sound caused by inhalation of air in the protection cover through an air intake vent when the cooling fan causes a wind. In this working machine, each of air intake vents for taking cooling air into the protection cover is formed in an upper surface side of the protection cover and in each of wall parts oriented in a direction opposite to a direction visible from an operator in the cabin.
