Abstract:
A starter comprising:a motor for generating a rotary driving force;a driving shaft driven by the motor and formed with a helical spline on an outer peripheral surface;a pinion moving body having a pinion gear for meshing with a ring gear of an engine and fitted through a spline-fitting on the driving shaft movably in an axial direction;a rotation restricting device engageable with the pinion moving body for restricting rotation of the pinion moving body;a driving device for driving the rotation restricting device to the pinion moving body; anda resilient restricting member biased with an initial load in a direction opposite to a rotation direction of the driving shaft,wherein the pinion moving body is rotatable together with the rotation restricting device only when receiving a rotary force in excess of a predetermined level in a rotation direction from the driving shaft upon engagement of the rotation restricting device.
