ABSTRACT:
A starter for an internal combustion engine including mechanical components subject to an impact load during operation including a shift lever, internal gear, gear cover formed integrally with the internal gear, front case, center bracket, and brush holder disposed in a rear bracket. At least one of the mechanical components is formed of a synthetic resin having a glass transition temperature greater than 90.degree. C. such as an aromatic copolymer and nylon series, whereby a workability and an impact load absorbing capacity of the mechanical components as well as the bending rupture strength are capable of withstanding an impact load caused by an abnormal operation of the starter at a high environmental temperature greater than 150.degree. C.
