Abstract
In a starter for an engine, a magnet switch attracts a plunger by a magnetic force generated by a solenoid coil wound around a sleeve, so that a pinion fitted on an output shaft of a starter motor is driven by movement of the plunger to engage with an engine ring gear. The the plunger is pressed to contact tightly with the sleeve, whereby the relative movement between the plunger and the sleeve is restricted as long as the coil is held deenergized. The pressing may be attained by an inclined surface provided on the plunger or a flexture of a transmitting member which connects the plunger and a pinion.
