Abstract
A starter for an internal combustion engine includes a motor, a pinion gear connected to the motor to be engaged with a ring gear of the engine. The pinion gear has teeth of a negative addendum modification whose number is larger than a standard gear that has the same outside diameter. Therefore the gear ratio of the pinion gear to the ring gear can be increased without change of the outside diameter thereof.
