Abstract
A coaxial engine starter comprising an electric motor including a brush assembly, an output shaft with a pinion and slidable relative to the motor and a solenoid switch having a movable iron core for closing and opening switch contacts. A cylindrical member rearwardly extends from the rear end of the brush assembly of the motor to surround a contact operating space in which the switch contacts move and has a rear edge located close to a front end of the movable iron core to define a small clearance therebetween. A shield member is also disposed behind the movable contact and has an outer edge located close to the rear edge of the tubular member and defines a radially small clearance therebetween. Thus, the cylindrical member and the shield member substantially surround the contact operating space and they are in a telescopically movable relationship relative to each other.
