Abstract

See full text

A protective sleeve for a motor component includes a cylindrical-shaped braided cord of twenty-four or more strands using both a multifilament strand and a monofilament strand made of synthetic fibers having a melting point or a decomposition temperature at 280.degree. C. or more. The protective sleeve has oil resistance at high temperatures of 50% or more, the oil resistance at high temperatures being represented by the following formula: oil resistance at high temperatures (%)=(T/T).times.100. Here, T denotes a tensile strength of the protective sleeve before a treatment and T' denotes a tensile strength of the protective sleeve after the treatment. 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 protective sleeve 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.degree. C. for 1,000 hours.
