り、結果として生産性の低下を招いた。2. Description of the Related Art An exterior case of an air conditioner having a long discharge port 1 is liable to warp during molding due to a long edge of the discharge port 1. This is particularly severe when the rim is formed to be narrow. Therefore, conventionally, in order to eliminate the warp, a metal bar for reinforcement is placed on the back side at a place where the warp is likely to occur to suppress the warp. In this way, the loading of the metal rod was performed in a separate process, so that the number of processes was increased. Also,
In order to eliminate the warp, the edge portion where the warp is likely to occur may be made thicker. However, in such a case, it takes a long time to cool the thick part of the muk, and the molding cycle is deteriorated. As a result, productivity is reduced.

After the gas injection, the molten resin is further injected to obtain a molding method that fills the mold cavity, and is an exterior case body 3 of an air conditioner having a long discharge port 1, and an edge 2 of the discharge port 1. Is made thicker than other parts and is made to be a closed hollow. Usually, a wind direction changing blade and an opening / closing door are attached to the discharge port 1, but these are not shown in the drawing. The nitrogen such as a gas forms a <br/> hollow portion 4 of the sealing selectively enters at is pressurized and injected from the outer surface portion to the rim of the outlet port 1 to the thick portion. In the drawings, no draft is provided, but it is actually provided.
