In detail, a shielded coupling surface 131 may be formed at an end of the fixing part 130 . The coupling surface 131 may face the first surface 64 of the chassis frame 60 while the motor mount 100 is seated on the chassis frame 60 .

A fixing hole 133 through which the fastening member 90 passing through the first surface 64 passes may be formed in the coupling surface 131 .

In addition, the protrusion 132 may be formed on the upper end of the coupling surface 131 . The protrusion 132 may be formed by bending one end of a plate-shaped material.

The motor mount 100 is fastened through the first surface 64 and the fixing hole 133 while the protrusion 132 is seated on the second surface 65 of the chassis frame 60 . The member 90 may be fixed to the chassis frame 60 .

Meanwhile, a forming part 160 that is depressed outwardly may be formed on a side surface of the motor mount 100 . The forming part 160 is for reinforcing the strength of the motor mount 100 , and is formed to have a long length to supplement a structure vulnerable to load or torsion.

The forming part 160 may be formed in the longitudinal direction of the side of the motor mount 100 , and may be formed as a long one over the whole except for a part of both ends of the side of the motor mount 100 , It may be formed so that a plurality of them are arranged at intervals.

Meanwhile, the lower surface 112 of the mounting part may be a portion where the flowing air collides from below when the air flows due to the driving of the fan motor assembly 80 .

At this time, the lower surface 112 of the mounting part may be formed to become narrower in the downward direction, and the lower end may be formed to be sharp. Accordingly, when the air flows by the driving of the fan motor assembly 80 , air resistance is greatly reduced, and the air flow can be smoothed.

The lower surface of the mounting part 112 may include a guide part 113 that is formed along the longitudinal direction of the lower surface of the mounting part 112 and becomes sharper downward.

The guide part 113 may be formed so that a plurality of inclined surfaces are in contact with each other, and each inclined surface may be formed to be inclined downward toward the bottom.

Meanwhile, the guide part 113 may include outer guide parts 114 formed at both ends of the guide part 113 .

The outer guide part 114 may be formed to be inclined inward toward the lower side. Accordingly, the outer guide part 114 can guide the air that collides with the lower surface 112 of the mounting part to the inclined part 120 .

According to the structure of the motor mount 100 as described above, when the fan motor assembly 80 is driven, the air moving from the lower side to the upper side of the motor mount 100 is partially controlled by the guide unit 113 . It may be guided to the outside of the motor mounting unit 110 .

In addition, a portion may be guided to the inclined portion 120 having a relatively narrow width by the outer guide portion 114 . Also, as the inclined portion 120 is bent roundly and has a relatively narrow width, air resistance can be minimized when passing the inclined portion 120 . Accordingly, the flow of air inside the outdoor unit 1 can be smoothed, and noise generation due to air resistance can be greatly reduced.
