Abstract:
A starter comprising:an output shaft (1) driven by an electric motor (M);a plunger (4);an exciting coil (2a) for attracting the plunger;an overrunning clutch (3) having a pinion (3P) for engaging with a ring gear (50) and spline-connected to the output shaft; the plunger, the exciting coil and the overrunning clutch being arranged on the outer circumference of and coaxially arranged on the output shaft;a contact shaft (8) provided on one end thereof with a moving contact (8e) for contacting with a stationary contact (10a, 10b) so that electric power can be supplied to the motor, and arranged substantially parallel with the plunger; andmeans for reducing wear of said pinion and said ring gear by causing facing end surfaces of said pinion and said ring gear to contact each other, said wear reducing means comprising a contact shaft moving means for moving the contact shaft such that the moving contact is brought into contact with the stationary contact to supply power to the motor only after the plunger has been attracted and moved for a sufficient distance by the exciting coil to establish contact between the pinion and the ring gear.
