Abstract
An electromagnetic switch of an engine starter includes a pair of stationary contacts connectable to a starter motor, a movable contact disposed at a first distance from the pair of stationary contacts; a rod having one end that slidably supports the movable contact via an insulating member and a stopper that restricts axial movement of said movable contact, an electromagnetic coil unit that includes a plunger, a stator core, a spring that urges the movable contact against the stopper and an exciting coil which moves the rod by the plunger a second distance when excited, and an inclination rectifying member, disposed near the stationary contacts, for providing a rectifying surface disposed at a third distance from the movable contact to abut the movable contact when one of the stationary contacts wears to a preset degree. There is the following relationship between the first, second and third distances: the second distance>the third distance>the first distance.
