1. A starter for starting an engine mounted on a vehicle, comprising:
a motor that generates rotational force by being energized, the motor rotating about a rotational axis thereof; a pinion that transmits the rotational force of the motor to a ring gear of the engine when the pinion engages with the ring gear; and an electromagnetic solenoid fixed to a starter housing to be in parallel with the motor such that the rotational axis of the motor and an axial direction being a longitudinal direction of the electromagnetic solenoid are parallel, wherein
the electromagnetic solenoid includes:a pair of first fixed contacts disposed at an activation circuit of the motor;a first movable contact facing the pair of first fixed contacts, being movable in the axial direction to open and close the pair of first fixed contacts, the pair of first fixed contacts being closed when the first movable contact contacts with the pair of first fixed contacts and the first fixed contacts being opened when the first movable contact is separated from the pair of first fixed contacts;a first switch that intermittently cuts off a current supplied to the motor in response to the first movable contact opening and closing the pair of first fixed contacts, the first switch being opened when the first movable contact opens the pair of first fixed contacts and being closed when the first movable contact closes the pair of first fixed contacts;a suppression resistor connected to the activation circuit to be in series to the first switch, suppressing rush current flowing into the activation circuit when the first switch is closed;a pair of second fixed contacts disposed at the activation circuit, bypassing the suppression resistor;a second movable contact facing the pair of second fixed contacts, being movable in the axial direction to open and close the pair of second fixed contacts, the pair of second fixed contacts being closed when the second movable contact contacts with the pair of second fixed contacts and the pair of second fixed contacts being opened when the second movable contact is separated from the pair of second fixed contacts;a second switch that short-circuits the suppression resistor to make a short circuit path when the second movable contact closes the pair of second fixed contacts, the second switch releasing the short circuit path when the second movable contact opens the pair of second fixed contacts, the second switch being opened when the second movable contact opens the pair of second fixed contacts and being closed when the second movable contact closes the pair of second fixed contacts;a main solenoid including a main electromagnet when being energized and a plunger being pulled by the main electromagnet to move in the axial direction, wherein the main solenoid pushes the pinion out towards the ring gear in response to the plunger moving in the axial direction and drives the first movable contact and the second movable contact towards the pair of first fixed contacts and the pair of second fixed contacts respectively;a regulation member disposed to be movable between a regulated position and a released position, the regulated position regulating movement of the second movable contact not to contact with the pair of second fixed contacts when the second switch is being closed, the released position releasing movement of the second movable contact so as to allow the second movable contact to contact with the pair of second fixed contacts; anda sub solenoid forming a sub electromagnet when being energized, driving the regulation member to be at the regulated position when the sub electromagnet is ON and releasing the regulation member to be at the released position when the sub electromagnet is OFF, whereinthe sub solenoid is configured to control the sub electromagnet to be ON and OFF such that the regulation member is driven to be at the regulated position before the second switch is closed when the main solenoid starts to operate, so as to regulate the movement of the second movable contact and the regulation member is released to be at the released position when a predetermined time elapses after the plunger is pulled by the main electromagnet, so as to release the movement of the second movable contact. |
