Specifically, the diameter (for example, 1 to 1.5 mm) of the annular steel wire (3f) to (3h) corresponding to the maximum wind speed portion is set to the annular steel wire (3a) to other portions.
It is smaller than the diameter (for example, 2 to 3 mm) of (3e), (3i), and (3j). Further, among the annular steel wire (3f) ~ (3h), the annular steel wire (3f), the annular steel wire (3g), corresponding to the wind speed of the fan,

Since the wind speed is small at the center and outside of (c) and there is a part that generates the maximum wind speed between them, if all the annular steel wires are arranged at equal pitches and equal diameters, large air resistance will occur at the part where the wind speed is high. Occurs, and at the same time turbulent noise is generated, which causes an increase in the noise of the outdoor unit, but as described above, the annular steel wire (3f) ~
Since the air resistance is reduced by reducing the diameter of (3h), it is possible to reduce energy loss due to turbulent flow in the wake. Therefore, it is possible to greatly reduce the air resistance in the part where the blow speed of the fan is high, and if the air volume is the same as the conventional one, it is possible to reduce the number of rotations of the fan and, as a result, to reduce the blowing noise. Can be achieved. In addition, since the annular steel wires (3f) to (3h) have a corrugated shape, even if the diameter of the annular steel wire is reduced in order to reduce air resistance, there is no large reduction in strength, and the appearance is impaired.
