Title:
ENGINE STARTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/012167
Kind Code:
A1
Abstract:
In order to solve the problem of providing an engine starting device which has high reliability and with which a voltage reduction can be prevented without providing additional circuits, this engine starting device is equipped with an electric motor device, an output shaft that transmits rotational force from the electric motor device to a ring gear, a clutch device that is slidably fitted to the output shaft and to which rotational force from the output shaft is transmitted, an electromagnet switch device having a plunger that is attracted and driven when the electromagnet is excited, and a shift lever, one end of which is engaged by the plunger and the other end of which is engaged by the clutch device. This engine starting device is characterized in that the interior of the electric motor device is equipped with a resistor that suppresses a drop in the power supply voltage of the engine starting device to a prescribed value when the engine is started. Specifically, this engine starting device is characterized in that the resistor is configured using a field winding forming the electric motor device.
