PROBLEM TO BE SOLVED: To provide a transmission belt capable of keeping or holding a belt tension at a high level even if the transmission belt is used at a high temperature.SOLUTION: A core wire for being embedded in a belt body constituting the transmission belt is constituted of a fiber (A) including at least a polyarylene sulfide fiber (such as polyphenylene sulfide fiber). The fiber (A) may be a twist yarn including at least a polyarylene sulfide fiber multifilament (A1), and may be a twist yarn including at least one kind of multifilament (A2) selected from a polyamide fiber multifilament and a polyester fiber multifilament. Tensile elasticity of such the transmission belt is 10-45 N/(mm %) or so. |
