Abstract:
A starter, comprising:a motor, wherein the motor has an armature, a shaft end of which is supported with a bearing of an end frame so that the armature freely rotates; an electromagnetic switch, wherein the electromagnetic switch performs on and off control of power supply to the motor; an output shaft, wherein the output shaft is rotated by the motor; a one-way clutch, wherein the one-way clutch has a pinion gear that is movable on the output shaft in the axial direction of the motor and is fitted to the output shaft via a helical spline to transfer rotary motion of the output shaft to the pinion gear, and the pinion, gear engages with a ring gear of an engine by activating the one-way clutch in a direction away from the motor using a lever that is driven by an attraction force of the electromagnetic switch; a case, wherein the case has a bearing adjacent to the motor for supporting the output shaft; and a braking member comprising impregnation oil and having a plurality of lugs formed on an outer periphery of the braking member, wherein the braking member is fixed between the one-way clutch and the case, and applies a braking force to the one-way clutch, the braking force being produced by friction when the one-way clutch is attracted toward the motor via the lever and the braking member engages with the case to prevent the braking member from rotating.
