Abstract:
1. A device for starting an engine, comprising: a starter for starting said engine; and a control device for controlling said starter, said starter including said control device being capable of individually controlling each of said actuator and said motor, said control device carrying out control by using a first mode in which said motor is driven prior to drive of said actuator and a second mode in which said actuator engages said second gear and said first gear with each other prior to drive of said motor, and said control device switching selection between said first mode and said second mode based on a reduction rate in rotation speed of said engine, when a request for starting said engine based on an operation by an operator, wherein said control device switches selection between said first mode and said second mode based on a rotation speed of said engine and the reduction rate in rotation speed of said engine, when the request for starting said engine based on the operation by the operator, and wherein said control device selects said first mode when a magnitude of said reduction rate is smaller than a threshold value while the rotation speed of said engine is intermediate between a first reference value and a second reference value greater than said first reference value.
