摘要:
A starter is disclosed as having a housing carrying thereon a motor, and a pinion moving body including a pinion gear, operative to mesh with a ring gear of an engine to transfer a rotational force of the motor thereto, and a pinion shielding member connected to the pinion gear at a front end thereof. The pinion shielding member has an outer circular periphery, having an outer diameter greater than the diameter of the addendum circle of the pinion gear, and a bottomed cylindrical configuration formed with a hollow portion having a front opened end and a closed rear end. Further, a clearance between an inner circumferential periphery of the nose portion and the outer circular periphery of the pinion shielding member is minimized to avoid interference between the nose portion of the housing and the pinion shielding member.

The clutch outer 24 is formed in the planet carrier 24 that outputs the orbital motion of the planetary gear 23, and the outer regulating part 33 is formed in the central part of the planet carrier 24. In the outer regulating part 33, he round hole 33a is formed in the central part of the direction of the diameter. The anti-motor side of the armature shaft 2 is inserted through the round hole 33a. The end part of the armature shaft 2 is inserted into the inside of the concave section 26b that passes through the round hole 33a provided on the outer regulating part 33. The armature shaft bearing 34 that is press fit in the inner circumference of the concave section 26b supports the armature shaft 2 relatively rotatable. Consequently, the deflection of the armature shaft 2 can be controlled, and the deflection of the clutch outer 24 can be controlled in the range of the smooth torque transfer of the one-way clutch 7.

A starter includes a motor, an output shaft driven by the motor, a pinion gear provided on the output shaft, and a shifter. The output shaft has first helical splines that are formed on an outer periphery of the output shaft. The pinion gear has second helical splines that are formed on an inner periphery of the pinion gear to engage with the first helical splines. The shifter shifts the pinion gear along the output shaft through the engagement between the first and second helical splines, thereby bringing the pinion gear into mesh with a ring gear of an engine. Further, in the starter, X
