1. A starting device for engines comprising:
- a motor that generates torque;
a pinion gear that moves in an axial direction and engages to a ring gear of an engine, and transmits the torque of the motor to the ring gear;
a solenoid device having a first coil that forms an electromagnet by energization, and pushes out the pinion gear to the ring gear side via a shift lever that is driven by an attraction power of the first coil; and
an electromagnetic switch having a second coil that forms an electromagnet by energization, and opens and closes a main point of contact disposed on a motor circuit by an attraction power of the second coil;
wherein,the solenoid device and the electromagnetic switch are arranged integrally in series in an axial direction, while a magnetic plate that forms a part of a magnetic circuit between the first coil and the second coil is shared by the solenoid device and the electromagnetic switch.

Abstract
An electromagnetic switch unit comprises a solenoid device that pushes out a pinion gear to a ring gear side of an engine, and an electromagnetic switch that opens and closes a main point of contact of a motor circuit. The solenoid device and the electromagnetic switch are arranged in series in an axial direction, while a magnetic plate that forms a part of magnetic circuit between a first coil used for the solenoid device and a second coil used for the electromagnetic switch is shared by the solenoid device and the electromagnetic switch.
