Zusammenfassung:An engine starter device for vehicles which prevents a kick-back based on the crankshaft speed in a vicinity of a compression top dead point of an engine is provided.[Solution]A motor stage determination unit (801) included in a kick-back prevention unit (80B) determines, based on the direction of current flowing in each phase of an ACG starter motor (48), angle ranges of the ACG starter motor (48) as motor stages (MSTAGE). A momentary NE measurement unit (802) measures a momentary NE of a crankshaft (40) in each stage. For example, when the motor stage is switched every 10 degrees, a momentary NE during every 10 degrees is measured. An ignition control unit (803) delays the timing of engine ignition when, at a crank angle corresponding to a vicinity of the top dead point of the engine, the momentary NE is equal to or lower than a reference NE (NEref).
