The panel forming the opening / closing door 3 is formed by blow molding a blowable thermoplastic resin such as ABS resin, modified polyphenylene oxide resin, polycarbonate resin, polyamide resin, polypropylene resin. Then, during the blow molding, the partition walls 10, 10 of the ventilation passage 11 are formed by recessing the back wall 12 toward the front wall 15 and welding the back wall 12 to the front wall 15. In the illustrated embodiment, Both walls of the recessed portion are integrally welded to each other. That is,
At the time of blow molding, the partition walls 10 and 10 are formed by protruding the slide mold into the cavity of the mold for molding the back wall 12
In Fig. 2, concave ribs that are welded to the front wall are formed, and then the slide mold is retracted so that both walls of the concave portions of the ribs are pressure-bonded and integrated so that they are substantially perpendicular to the surface of the back wall 12. is there. As described above, since the ventilation passage 11 is formed by the partition walls 10 that are substantially perpendicular to the surface of the back wall 12,
Both sides of the connecting member 14 are connected to the ventilation connection port 13 by the partition walls 10, 1.
It can be attached closely and firmly to the state of being in close contact with 0. Similarly, the grill 17 can be attached closely and firmly. Further, since the back wall 12 of the opening / closing door 3 is formed in a flat shape, it has a good sealing property with the partition wall 6, and the partition sections of the electronic device units 7 and 8 housed in the upper and lower two stages are good. . Further, the partition walls 10, 10 connect between the back wall 12 and the front wall 15, and the partition wall 1
Nos. 0 and 10 are the ones in which both walls of the recessed portion are crimped and integrated, and have high rigidity. Therefore, the opening / closing door 3 does not cause abnormal vibration due to the cooling air flowing through the ventilation passage 11 and does not generate abnormal noise. Can be prevented.
