Abstract: An outdoor unit for an air-conditioning apparatus includes: a casing having an opening portion of an air passage formed in a front panel; and a fan guard, which includes a plurality of vertical rails and a plurality of horizontal rails that are combined with each other, and is configured to cover the opening portion. The fan guard includes: an upper locking portion formed on an upper end portion of a vertical rail and lower locking portions formed on lower end portions of the vertical rails. The upper locking portion is formed by bending the upper end portion toward the casing side so as to be inclined downward. The lower locking portions are formed by bending toward the casing so that the distal ends are directed downward. The front panel has: upper and lower temporary fixing holes configured to receive the upper and lower locking portions to be inserted thereinto.

Abstract: A fan motor support includes a rightward-and-leftward direction guide piece which projects in a direction of approaching a fan motor from a lower intermediate transverse plate or an upper intermediate transverse plate extending across a pair of support columns in a rightward-and-leftward direction at a position above or below the fan motor in a vertical direction at a distance apart from the fan motor. The rightward-and leftward direction guide piece is formed to be opened in a direction opposite to a machine chamber in a rightward-and-leftward direction and recessed toward the machine chamber. A rightward-and-leftward direction guide groove which is configured to change a wiring path of the lead wire of the fan motor hooked thereto to a direction toward the machine chamber from the upward-and-downward direction.
