A starter for automotive engines is provided which is equipped with a pinion carrier which is shifted by a magnetic attraction, as transmitted from a solenoid switch through a shift lever, to establish engagement of a pinion with a ring gear jointed to the engine. If thrust acting on the pinion carrier to urge the pinion against the ring gear through when the pinion has been shifted and hit the ring gear, so that the pinion is placed in abutment with the ring gear is defined as N (Newton), and the mass of the pinion carrier is defined as g (gram), a relation of g/N<=6 is met. This improves the ability of engagement of the pinion with the ring gear, thus resulting in an increased life span of the starter.
