2. Description of the Related Art An outdoor unit of an air conditioner includes, for example, one having components as shown in FIG. The main body of this outdoor unit is composed of a base 1, a synthetic resin front panel 2 and a rear cover 3 serving as a decorative cover, and a top cover 4, and the inside of the main body is mounted at a substantially central position on the front side of the base 1. A heat exchanger 6 provided over the rear side and both side faces of the compressor 5 and bent in a substantially concave shape; and a blower 7 provided facing the rear side of the heat exchanger 6. And a metal electrical component box 8A fixed to the upper end of a side plate 6a provided on both sides of the heat exchanger 6 and containing electrical components, and a cable (not shown) connected to one side of the electrical component box 8A. It is composed of a terminal board to be connected, a connection valve composed of a two-way valve 9a and a three-way valve 9b for connecting a connection pipe, and a valve fitting 9A for mounting the connection valve. FIG. 5 shows the inside of the outdoor unit from the front.

The valve fitting 9A has one end fixed to one side plate 6a of the heat exchanger 6 and the other end fixed to the fitting 7a of the blower 7 by screws, and the electrical component box 8A has one end fixed to the heat exchanger. The other end is fixed to the other side plate 6a by screwing to the upper surface of the valve fitting 9A. The printed wiring board 11 accommodated in the electrical component box 8A as shown in FIG.
c is opened and supported by a support member 12 inserted therethrough. A cylindrical capacitor 13 is provided with locking pieces formed at both ends of a mounting member 14 hanging from the upper part of the outer periphery of a hole 8 provided on the bottom surface of an electrical component box 8A.
d to be locked. Electrical component box 8
At the lower part of A, there is a blower 7 as shown in FIG.
d, etc., may enter the electrical component box 8A and adversely affect the internal electrical components. Therefore, in the conventional outdoor unit, as shown in FIG. 6, a sealing material 15 is attached to the bottom surface of the electrical component box 8A to prevent water from entering.

[0004]

However, sticking the sealing material 15 at a plurality of locations is troublesome, which contributes to an increase in cost, and has a problem in reliability in long-term use. The electrical component box 8A reinforces the upper cover 4 by holding the upper surface thereof close to the ceiling of the upper cover 4, so that the upper cover 4 can be used when a person or a heavy object is placed on the upper cover 4. Although the deformation and breakage of the top cover 4 are prevented, there is a problem that the electrical component box 8A and the valve attachment 9A cannot provide a sufficient holding force to reinforce the top cover 4 with the above structure. Therefore, an object of the present invention is to provide an outdoor unit of an air conditioner that solves these problems.
