Patent ID: 8169281

Claim:
A starter for engines comprising: a motor having an armature that generates torque, being energized from a battery by closing a main point of contact provided in a motor circuit; an output shaft to which the torque of the motor is transmitted via a clutch that has a clutch inner and a clutch outer; a pinion gear connected with a perimeter of the output shaft via a helical spline engagement; a switch coil that is energized from the battery by closing a starting switch; a return spring arranged at an anti-moving contact side of the switch coil in an axial direction; a plunger that moves in an inner circumference of the switch coil in response to a magnetism that the switch coil generates; and an electromagnetic switch that opens and closes the main point of contact interlocked with a motion of the plunger and pushes out the pinion gear in a direction of an anti-motor side via a shift lever, wherein a motor side end of the output shaft is formed unitarily with the clutch so that the output shaft does not move in an axial direction relative to the clutch inner, wherein the electromagnetic switch is composed with one coil such that the switch coil and a starting circuit are separated electrically, and wherein the pinion gear is pushed out in the direction of the anti-motor side along with the helical spline on the output shaft via the shift lever interlocked with the motion of the plunger without moving the clutch in the direction of the anti-motor side.
