Abstract
An inertia starter for an internal combustion engine comprises a driving shaft driven by a DC motor and provided with a one-way clutch which includes an axially movable driving member rotating and axially moving as the driving shaft is rotated and a driven member driven by the driving member to be axially displaced together with the driving member, a pinion secured to the driven member, an engine ring gear adapted to removably engage with the pinion, a return spring for returning the one-way clutch together with the pinion to the original position, a rotatable holder plate provided on the one-way clutch, and an electromagnet mounted on a stationary portion in opposition to the holder plate with a predetermined distance therefrom. The electromagnet has a coil connected in parallel with the field winding of the DC motor or with a part of the armature winding thereof.
