Abstract

A starter for an engine is equipped with a planetary gear train as a torque variator to change torque used to start the engine. The torque variator is capable of changing the degree of torque which is transmitted between a planetary carrier and an outer gear of the planetary gear train, thereby changing a ratio of speed of a sun gear to speed of the planetary carrier of the planetary gear train to increase or decrease the degree of torque required to start the engine. This ensures the stability in starting the engine, for example, in cold conditions and achieves a quick start of the engine as needed.
