Starter for an engine having a pinion moving member
First Claim
1. A starter comprising:
- a starter motor including a cylindrical yoke, field magnetic poles fixed to an inside surface of the yoke and an armature rotatably supported inside the poles;
an output shaft disposed at one axial side of the armature to be driven by the starter motor;
a pinion provided on the output shaft and engageable with a ring gear of an engine;
a magnet switch disposed at another axial side of the armature and having a fixed contact and a plunger which has a movable contact, the magnet switch energizing the starter motor when the movable contact contacts the fixed contact by a movement of the plunger;
pinion movement means to move the pinion to the ring gear; and
a cord-shaped member connecting the plunger of the magnet switch and the pinion movement means and extending axially between the armature and the yoke;
wherein the pinion is moved to the ring gear when the cord-shaped member is pulled tight by the movement of plunger.

Abstract
A starter which reduces the number of parts for a pinion rotation regulation and provides an accurate magnet switch operation. A concave portion is formed on the bottom side of a plunger to store a spherical body set on the rear end of a cord-shaped member, e.g., wire. A male screw is formed on the inner wall of the concave portion, and a fixing screw that fixes the spherical body is screwed into this male screw so that the length of the cord-shaped member is adjusted. The length of the string-shaped member is adjusted so that when a plunger shaft moves upward and a lower movable contact contacts a terminal bolt, the claw of the pinion rotation regulating member fits into the notch on the outer circumference of a pinion gear. Furthermore, the claw is is fit into the notch via the wire when the plunger moves.

8. A starter comprising:
-
a starter motor including field magnetic poles and an armature disposed inside the field magnetic poles; an output shaft driven by the starter motor; a pinion provided on the output shaft and engageable with a ring gear of an engine; a magnet switch disposed at an axial side of the starter motor oppositely to the pinion, said magnet switch having a fixed contact and a plunger which has a movable contact that energizes the starter motor when the movable contact contacts the fixed contact by the movement of the plunger; pinion regulating means to regulate at least one of pinion operations including a pinion movement toward the ring gear and a pinion disengagement from the ring gear; and a connecting member to drive the pinion regulating means by the plunger of the magnet switch, wherein the connecting member extends axially through a space existing radially outside the armature. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)
