Abstract:
1. A binding cord for a motor for an electric vehicle comprising a braided round cord of eight or more strands using a multifilament strand made of synthetic fibers having a melting point or a decomposition temperature at 280° C. or more, wherein the binding cord has oil resistance at high temperatures of 50% or more, the oil resistance at high temperatures being represented by the following formula: where T denotes a tensile strength of the binding cord before treatment and T′ denotes a tensile strength of the binding cord after the treatment, wherein the tensile strength is measured in accordance with JIS L1013-8.5.1, and the treatment is carried out in such a manner that the entire binding cord is put into a closed container containing a mixture of 5 weight % of water and 95 weight % of automatic transmission fluid, followed by heating the container so that a temperature of the mixture is maintained at 150° C. for 1,000 hours, and wherein a shape of the binding cord is in a tube form and in an oblate form.
