Abstract

PURPOSE:To improve the wear resistance and the bend resistance of a timing belt and further obtain its excellent characteristic against the deterioration at a wet and hot time, by forming a tension resisting body by specific aromatic polyamide fiber. CONSTITUTION:A timing belt is formed by using aromatic polyamide fiber as a tensile member. The aromatic polyamide fiber is composed of a repeating unit shown by the structural formula written in the right column, and at least 7.5mol% of the total amount of Ar1, Ar2, Ar3 in the repeating unit is composed of any one sort or more of the formulas 1, 2, 3. Furthermore, its tensile strength at room temperature is made to be 10g/d or more, and its initial Young's modulus is made to be 300g/d or more.
