摘要： An engine start system which may be employed in automotive idle stop systems. To start an engine, the system brings a pinion gear into engagement with a ring gear coupled to the engine and turns on an electric motor to rotate the ring gear through the pinion gear to crank the engine. When it is requested to start the engine during deceleration of the engine before stop thereof, the system thrusts the pinion into engagement with the ring gear and then turns on the motor to rotate the pinion gear, in other words, delays the activation of the motor until after the pinion gear has engaged the ring gear. This minimizes mechanical impact or noise arising from the engagement of the pinion gear with the ring gear and improves the reliability in engagement with the ring gear during the deceleration of the engine and durability of the system.

摘要： A solenoid for pushing out a pinion pushes out a pinion gear to a ring gear side and a switch for motor energization that opens and closes a motor point of contact have a solenoid coil and a switch coil that form an electromagnet by energization, respectively. A fixed iron core used commonly by both coils is arranged between the solenoid coil and the switch coil. A solenoid yoke that covers a perimeter of the solenoid and a switch yoke that covers a perimeter of the switch are formed integrally as a whole yoke in an axial direction.

摘要： A starter includes an electromagnetic solenoid that generates force for pushing a pinion gear 6 to a ring gear side, and an electromagnetic switch that opens and closes a motor contact point. When idle-stop is performed, an ECU energizes a solenoid coil of the electromagnetic solenoid during inertial rotation until the ring gear stops rotating. After rotation of an engine is stopped, the ECU stops energizing the solenoid coil. As a result, in the starter, the pinion gear can mesh with the ring gear that is rotating by inertia without use of the rotational force of a motor. The meshed state can be maintained even after energization of the solenoid coil is stopped.

摘要： A starter to start an engine mounted on a vehicle provides an electromagnetic solenoid to push a pinion gear towards a ring gear side, an electromagnetic switch to open and close a motor contact point. The electromagnetic solenoid and the electromagnetic switch are individually controlled by an Electronic Control Unit i.e., ECU. When an idle-stop is triggered, the ECU controls a starter relay to be closed during the ring gear is rotating whereby the pinion gear together with a clutch are pushed out to counter-motor direction by the electromagnetic solenoid. As a result, the pinion gear meshes with the ring gear that is rotating at lower rotational speed. Therefore, the inertial mass of the starter is added to the ring gear so that swinging of the engine can be suppressed.

摘要： Terminal-bolts and a fixed contact are formed with different kinds of metals, and fixed to a fixing hole formed in the fixed contact by press fitting one end of the terminal-bolts. A plurality of concavo-convex parts is provided on a surface of the fixed contact that faces the movable contact. A plurality of concavo-convex portions is provided on another surface of the fixed contact that faces an anti movable-contact side. The concavo-convex portions are arranged so that positions of concave parts of the concavo-convex portions match positions of convex parts of the concavo-convex portions provided in the opposite surface of the fixed contact. The concavo-convex parts are at least partly curved, and have the same height and project in a height direction from the fixed contact.
