PROBLEM TO BE SOLVED: To provide a resin composition having high heat resistance and strength withstanding use under high temperature conditions and also having high vibration resistance.SOLUTION: Provided is a resin composition for an engine supporting member containing: a polyamide resin (A)in which a glass transition temperature measured with a differential scan calorimeter is 80 to 150°C and a melting point is 300°C in 29.89 to 68.9 mass%; a polyamide resin (B) whose melting point is not substantially measured in 0.1 to 20 mass%; a fibrous filler (C) in 30 to 70 mass%; and a heat stabilizer (D) in 0.01 to 3.0 mass% (the total of the (A) to (D) is 100 mass%), the polyamide resin (A) includes a dicarboxylic acid component unit at least including a terephthalic acid component unit of 20 to 100 mol and the other aromatic dicarboxylic acid component unit of 0 to 80 mol% or an aliphatic dicarboxylic acid component unit of 0 to 40 mol% having the carbon atom number of 4 to 20 and a diamine component unit including an aliphatic diamine component unit having the carbon atom number of 4 to 20.SELECTED DRAWING: Figure 1

    【課題】高温条件下での使用に耐える高い耐熱性と強度とを有し、かつ高い振動耐性を有するエンジン支持部材用樹脂組成物を提供する。【解決手段】示差走査熱量計で測定されるガラス転移温度が80〜150℃、融点が300℃以上であるポリアミド樹脂(A)29.89〜68.9質量%、融点が実質観測されないポリアミド樹脂(B)0.1〜20質量%、繊維状充填材(C)30〜70質量%及び耐熱安定剤(D)0.01〜3.0質量%を含有し((A)〜(D)の合計が100質量%)、ポリアミド樹脂(A)は、テレフタル酸成分単位20〜100モル%と、それ以外の芳香族ジカルボン酸成分単位0〜80モル%及び炭素原子数4〜20の脂肪族ジカルボン酸成分単位0〜40モル%の少なくとも一方とを含むジカルボン酸成分単位と、炭素原子数4〜20の脂肪族ジアミン成分単位を含むジアミン成分単位とを含む、エンジン支持部材用樹脂組成物。【選択図】図1
