1. A starter comprising:
- a motor;
an electromagnetic switch that turns on/off power supply to the motor;
a clutch that transmits rotative force from the motor to a pinion gear to be engaged with a ring gear in an internal combustion engine, and that is reciprocally movable relative to the ring gear;
a shift lever that is coupled at its one end portion with a plunger of the electromagnetic switch, and that has a straddle portion in a bifurcated form of its other end portion straddling the clutch;
a shift piece for joining the clutch and the shift lever together, that is relatively rotatably fitted to a groove of the clutch, and is also relatively rotatably coupled with the straddle portion of the shift lever;
wherein the shift lever makes its pivotal seesaw motion in conjunction with a reciprocal movement of the plunger, and the pinion gear is engaged with or released from the ring gear by a reciprocal movement of the clutch in conjunction with the pivotal seesaw motion, andwherein the shift piece is configured separately by a ring-like shift piece (shift piece A) mounting to the groove of the clutch, and another shift piece B mounting to the shift lever, the shift piece A and the shift piece B being mounted in a form coupled together,wherein shift piece B continuously extends at least halfway around a circumference of the ring-like shift piece (shift piece A),wherein the ring-like shift piece has a groove formed on its ring-like circumference portion for joining and supporting the shift piece B and a latching recess for the shift piece B formed on the groove,wherein the groove has a first wall face and a second wall face opposite the first wall face extending along its ring-like circumference portion,wherein the shift piece B has a first lateral side portion and second lateral side portion, andwherein the first wall face and the first lateral side portion are configured to respectively contact with and push against each other, and the second wall face and the second lateral side portion are configured to respectively contact with and push against each other.

Abstract
A starter which includes a shift piece that is relatively rotatably fitted to a groove (6) of a clutch and is also relatively rotatably coupled with a straddle portion of a shift lever (9), for joining the clutch and the shift lever together, so that a pinion gear is engaged with or released from a ring gear by a reciprocal movement of the clutch that is in conjunction with pivotal seesaw motion of the shift lever (9), wherein the shift piece is configured separately by a ring-like shift piece (7) mounting to the groove (6) of the clutch and a shift piece B (8) mounting to the shift lever, which are mounted in a form coupled together.
