PURPOSE: To reduce the wear, mechanical output losses, noise generation, and the natural frequency of a drive train even in a starter in which the impact generated in the form of a rotational pulsation in closing a free wheel clutch especially in an idling stage and the load moment peak are effectively damped, and the output is relatively large. CONSTITUTION: A spring accumulator 28 provided with a preload torque Mv effective in the driving direction is arranged in a starter drive train 100, and the preload torque Mv is 15-50% of the stall torque Mk for the pinion rotationρR of a starter motor 11. In the starter drive train 100 formed from the starter motor 11 to the connection pinion 22 of a starter 10 without any spring accumulator 28, the ratio CSt0 /CF of the torsional rigidity CSt0 on the stall moment Mk and the torsional rigidity CF effective at a connection pinion 22 of the spring accumulator 28 must be at least 4. |
