Claims

[Scope of utility model registration request]

A pop-up dog having an engaging claw that can be engaged with the engaging protrusion of the crank pulley is spline-fitted onto a spline shaft linked to the starter motor, and the dog is moved along the spline shaft toward the crank pulley, and the In the starter device for an internal combustion engine, the internal combustion engine is started by engaging an engaging claw with the engaging protrusion, wherein a pop-up dog is provided at an end of a center shaft that rotatably supports the helical spline shaft. A retainer is provided for regulating the position of the engagement claw, and the side end portion of the engagement claw is provided to be engageable with the engagement piece of the retainer, so that the pop-up dog and the helical spline shaft can be rotated synchronously, and the position adjacent to the engagement claw is is provided with a notch for receiving the engagement piece and for defining the amount of movement of the pop-up dog;
A motor unit is provided with a concave portion that opens outward in a position adjacent to the driven gear that is integrated with the helical spline shaft, and is equipped with a starter motor, a battery for driving the motor, an operating switch, and a starter pinion that can mesh with the driven gear. A starter device for an internal combustion engine, characterized in that the unit is provided separably from the internal combustion engine side, the unit is removably mounted in the recess, and the starter pinion is removably engaged with a driven gear.
