ABSTRACT:
A starter pinion shifting arrangement comprising a solenoid switch having a hook which can be pulled by a plunger which can be electromagnetically actuated through a compression spring, and a shift lever connected between the hook and a sliding thrust and a pinion movement unit slidably mounted on a support shaft and including a pinion engageable with a driven gear. A clearance is provided through which the hook can be pulled by the plunger when the hook is in a stopped position when the pinion is in a stopper abutting position in which the pinion moved by the attraction toward a stationary core of the plunger is in engagement with the driven gear. An elastic member, which is flexed through said shift lever by the compression force of the compression spring when it is flexed as the pinion movement unit is in the stopper abutting position in which the pinion is in engagement with the driven gear, may be disposed in an engagement portion between the shift lever and the pinion movement unit. The compression spring may comprise two parallel mounted springs, the two compression springs act to urge the pinion to the driven gear when the pinion is in abutment with the driven gear, and only one of the two compression springs acts when the pinion is in the stopper abutting position in which the pinion is in engagement with the driven gear.
