Zusammenfassung:	PURPOSE:To produce low cost propylene resin housing, which is excellent in self tapping repeating strength, rigidity and appearance and has small molding warpage and eliminates the necessitites for inserting nuts, making wall thicker and taking anti-warpage measure. CONSTITUTION:The manufacturing method of propylene resin housing consists of the melt-kneading of propylene polymer modified by unsaturated carboxylic acid or its derivative with a kneader and the following feeding and kneading of glass fiber to and with the melt flow of the propylene polymer in the midway for obtaining propylene resin composition in order to obtain the housing concerned by injection molding.
