The projecting portion 81d is formed (see FIG. 5). Therefore, here, the strength of the first and second support members 74 and 75 can be further improved, and thus the strength of the motor support base 70 can be further improved.

<E>
Here, as described above, the folded-back portion 84 extending toward the front side is formed at the edge portion of the rear plate portion 82 where the side plate portion 83 is not connected (see FIG. 8 ). Therefore, here, the strength of the first and second support members 74 and 75 can be further improved, and thus the strength of the motor support base 70 can be further improved.

In this case, the third bulging portion 81d may also be formed on the rear plate portion 82. Then, the first bulging portion 82a may be formed on the front plate portion 81.

Even in this case, the same effect as that of the above embodiment can be obtained.

As described above, in the first and second support members 74 and 75, the mounting portion 81a is formed on one of the front plate portion 81 and the rear plate portion 82, and the first bulging portion 82a is formed. It suffices that it is formed on the other of the front plate portion 81 and the rear plate portion 82.

<B>
In the outdoor unit 2 (refrigeration apparatus unit) of the above-described embodiment and modification A, the fan motor 25 is fixed to the mounting portions 81a of the first and second support members 74 and 75 via the motor fixing member 71. However, it is not limited to this. For example, the fan motor 25 may be directly fixed to the mounting portions 81a of the first and second support members 74 and 75.

<C>
In the outdoor unit 2 (refrigerator unit) of the above-described embodiment and modified examples A and B, one blower 23 (one set of fan 24 and fan motor 25) is supported by the motor support base 70 as an example. However, the present invention is not limited to this. For example, the configuration may be such that two or more blowers (two or more sets of fans and fan motors) are vertically supported and supported by the motor support base.

<D>
Although the outdoor unit 2 is described as an example in the above-described embodiment and modification examples A to C, the invention is not limited to this. Any refrigerating machine unit may be used as long as the fan motor of the blower is supported by the motor support with the rotation shaft extending in the front-back direction.

Although the embodiments of the present disclosure have been described above, it will be understood that various changes in form and details can be made without departing from the spirit and scope of the present disclosure described in the claims. ..

The present disclosure can be widely applied to a refrigeration apparatus unit in which a fan motor of a blower is supported by a motor support base with a rotation shaft extending in the front-rear direction.
