Claims

[Claims for Utility Model Registration] 1. A relay that operates a starter that starts the engine is operated in response to the turning on of a starter switch, and a voltage corresponding to the rotational speed of the engine is detected and the value is at a predetermined level. In a starter protection device that stops the operation of the relay and stops the operation of the starter when the relay coil exceeds a relay operating circuit; a control circuit connected to the relay operating circuit and controlling the operation of the relay operating circuit according to its logic output; and a control circuit whose timer output causes the logic output of the relay operating circuit to be inoperative. A starter protection device comprising: a timer circuit connected to the circuit; 2. The starter protection device according to claim 1, wherein the timer circuit is configured to output a timer signal from when the engine stops until rotation of a ring gear of the engine stops. . 3. Claim 1, wherein the timer circuit is configured to output a timer signal from when the starter switch is turned off until the pinion of the starter or the ring gear of the engine stops. or the starter protection device described in 2.
