However, in the former method, as is apparent from FIG. 6, it is necessary to form a large number of ventilation openings 201 so that the support plate 200 does not obstruct the ventilation. However, there is a problem that it takes time to process the support plate. A male motor (bolt) 203 provided on the support plate 201 is connected to a fan motor 205.
Nut through the fixing hole of the fan motor 205
Is fixed to the support plate, but since the fan motor 205 is heavy (for example, about 5 kg), there is a problem that the operation of passing a screw through the fixing hole is troublesome and the fan motor 205 cannot be easily installed.

[0006] In particular, it is inferior in workability to pass a plurality of male screws 203 projecting at predetermined intervals in advance so as to coincide with all the fixing holes formed in the fan motor 205 because of a low degree of freedom. There is a point.

Further, in the latter method, since the support plates which are left and right asymmetric are used, it is necessary to work while confirming the mounting positions of the respective support plates, and the number of parts cannot be denied.

Accordingly, the present invention provides an outdoor unit of an air conditioner in which the installation of the fan motor is easy and the processing of the support plate is easy, and the number of parts is reduced.
