Abstract: PURPOSE:To improve the mechanical characteristics and the durability by executing the injection molding of the resin composition by melting and mixing the polyphenylene sulfide resin, the polyphenylene oxide and the fibrous and/or the non-fibrous fillers. CONSTITUTION:The polyphenylene sulfide resin(PPS resin) is the polymer containing more than 70% of repeated unit demonstrated by the constitutional formula I, while the polyphenylene oxide(PPO) is fundamentally composed of the constitutional unit demonstrated by the constitutional formula II. In the formula II, R1-R4 mean the hydrogen atom, the halogen atom, the aromatic hydrocarbon radical. A cylinder head cover for an automobile is obtained by executing the injection molding of the resin composition which is obtained by melting and mixing 100 pt.wt. of the PPS resin, 10-20 pt.wt. of the PPO resin, and 50-400 pt.wt. of the fibrous and/or non-fibrous filler. This secures higher mechanical strength, higher rigidity, the dimensional stability or the like even at high temperature of 100 deg.C.
