The side plate 11 is attached to the bottom frame so as to be in contact with the outer surface of the upright edge 7 of the bottom plate 2. The notch 12 provided in the side plate 11 is provided at a position corresponding to the valve mounting portion 8 when the side plate 11 is mounted on the bottom frame. Therefore, when the side plate 11 is mounted on the bottom frame, the outer peripheral portion of the closing valve mounting plate 1 comes into contact with the peripheral portion of the notch 12 from inside, and the valve mounting portion 8 is exposed to the side from the notch 12 and the inner peripheral edge of the notch 12 is formed. It comes into contact with the connecting portion 9.
And the insertion end 15 formed above the valve mounting portion 8 is
It is inserted into the cut hole 17 from below. FIG. 2 is a view showing a portion where the insertion end 15 is inserted into the cutout hole 17 in FIG.
It is -A sectional drawing. As shown in the figure, the insertion end 15 inserted from below into the cut hole 17 is
The closing valve mounting plate 1 and the side plate 11 are connected so as to be sandwiched between the side plate 11 and the inner surface 22 of the side plate 11.

In the outdoor unit of the air conditioner, the closing valve mounting plate 1 and the side plate 11 are connected by inserting the insertion end 15 of the closing valve mounting plate 1 into the cutout hole 17 of the side plate 11. . Therefore, screws and the like which have been required in the past become unnecessary, thereby reducing the number of parts. Also, the insertion end 15
The closing valve mounting plate 1 and the side plate 11 are connected only by the operation of inserting the through hole 17 into the notch hole 17, and the screwing operation as in the related art is unnecessary, so that the number of assembling steps of the outdoor unit can be reduced.

The insertion end 15 is sandwiched between the outer surface 21 of the recess 16 and the inner surface 22 of the side plate 11. Therefore, although the assembling work is simplified, the connection between the side plate 11 and the shut-off valve mounting plate 1 can be ensured.

A connecting portion 9 is provided around the valve mounting portion 8,
The connecting portion 9 and the inner edge of the notch 12 are in contact with each other. Since the connecting portion 9 is formed so as to obliquely intersect the plate surface of the side plate 11, even if there is a slight error in the size of the notch 12 and the combination position with the closing valve mounting plate 1,
The inner edge of the notch 12 comes into contact with any part of the connecting portion 9. Therefore, the side plate 11 and the closing valve mounting plate 1 can be reliably positioned and fixed by the engagement between the valve mounting portion 8 and the notch 12. Further, since the insertion end portion 15 is provided with the notch inclined portion 23 so as to be shorter toward the distal end side, insertion into the cutout hole 17 can be started smoothly. The concave connecting portion 20 is also provided around the concave 16.
The insertion end 15
Is held between the inner side surface 22 of the side plate 11 and the recess connecting portion 20, so that the closing valve mounting plate 1 and the side plate 11 can be reliably connected. Further, since the closing valve mounting plate 1 and the side plate 11 are not connected by screws, even if maintenance work or the like is frequently performed, there is no problem such as abrasion of the screw thread.
And the side plate 11 can always be reliably connected.

Further, in the outdoor unit of the air conditioner, the bottom plate 2 and the closing valve mounting plate 1 are integrally formed by a single member. Therefore, the number of parts can be reduced and the cost can be further reduced. Since the closing valve mounting plate 1 and the side plate 11 are not connected by screws, even if the closing valve mounting plate 1 has such a thickness that a screw hole having a sufficient length cannot be formed, the side plate 11 and the side plate 11 are closed. The connection of the valve mounting plate 1 can be reliably performed. Therefore, the closing valve mounting plate 1 is
Even if the thickness is the same as above, the connection between the closing valve mounting plate 1 and the side plate 11 does not become insufficient.

Although the specific embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and can be implemented with various modifications within the scope of the present invention. For example, in the above description, the recess 16 is provided in the side plate 11, and the insertion end 15 is located between the outer surface 21 of the recess 16 and the inner surface 22 of the side plate 11. However, in this case, a projection may be provided on the side plate 11, and the insertion end 15 may be located between the inner surface of the projection and the outer surface of the side plate 11. In the above description, the cutout hole 17 is opened up and down, and the insertion end 15 is inserted from below. However, in this case, the cutout hole 17 is opened in the side plate 11 in the lateral direction, and the insertion end portion 15 formed by bending the end of the closing valve mounting plate 1 in the lateral direction is inserted into the side plate 11 from the lateral direction. Good.
