Abstract
A first distance between a position where a point-of-action end abuts at a rear end surface of a push-side abutting portion (flat washer) forming a part of holder and a rotational axis of a pinion, and a second distance between a position where the pinion abuts at a front end surface and the rotational axis of the pinion have the relation of first distance>second distance. Thereby, after starting an engine, even when the pinion is rotated at high speed, the push-side abutting portion is less likely to rotate and remains stationary relative to the lever, and even though the push-side abutting portion begins to rotate, it is rotated at a lower speed than the pinion.
Claims8
A starter comprising:
- a pinion pushed to a front in an axial direction by receiving a magnetic attraction force of an electromagnetic switch as thrust acting in the axial direction, and rotated by a torque of an electric motor;
- a resin-made lever assembled rotatably around a predetermined fulcrum, which has a point-of-action end for transmitting the magnetic attraction force as thrust to the pinion;
- and
- a push-side abutting portion assembled to the pinion relatively rotatably, pushed to the front in the axial direction in response to an abutment of the point-of-action end of the lever when the lever is rotated by the attraction force, and the push-side abutting portion abutting the pinion from the rear in the axial direction to push the pinion to the front in the axial direction;
- wherein,
- the push-side abutting portion has two end surfaces perpendicular to the axial direction formed in a flange shape, one of the end surfaces receives the abutment of the point-of-action end of the lever, while the other one of the end surfaces abuts the pinion from the rear in the axial direction;
- and
- a first distance between a position where the point-of-action end of the lever abuts at one of the end surfaces and a rotational axis of the pinion, and a second distance between a position where the pinion abuts at the other one of the end surfaces and the rotational axis of the pinion have a relation that the first distance is greater than the second distance.
