摘要： In an engine starting apparatus, together with a one-way clutch, a pinion is pushed toward a ring gear of an engine mounted in a vehicle. The one-way clutch has an idling torque smaller than a torque of the ring gear that tries to turn the pinion when the pinion is pushed to the ring gear. By a control device, a pinion pushing device is enabled to operate when i) the revolution speed of the ring gear is larger than a revolution speed of the pinion and ii) a relative revolution speed between the revolution speed of the ring gear and the revolution speed of the pinion is a desired value.

摘要： An electromagnetic solenoid having an electromagnetic coil, a fixed iron core, a movable iron core, and a spring coil. The spring coil, arranged between the fixed and the movable iron core, supplies a spring force to the movable iron core toward an opposite direction of the fixed iron core along the axial direction. A magnetic attraction surface and a fitting part are formed in at least one of the fixed iron core and the movable iron core. The magnetic attraction surface is contacted with the fixed iron core when the movable iron core reaches the fixed iron core. An outer peripheral surface of the fitting part, apart from the magnetic attraction surface by a predetermined distance along the axial direction, is engaged with the spring coil. The most outer peripheral part of the magnetic attraction surface is positioned inside rather than the most outer peripheral part of the fitting part.

摘要： In a system, a starter includes a motor for rotatably driving an output shaft with a pinion and an actuator that shifts the pinion toward a ring gear to be engaged with the ring gear. A monitor unit monitors a rotational speed of the internal combustion engine. The rotational speed of the internal combustion engine drops after an automatic control for stop of the engine. When an engine restart request occurs with the rotational speed being within a preset range during the rotational speed of the internal combustion engine dropping by the automatic control for stop of the engine, a drive unit drives the actuator to shift the pinion toward the ring gear to be engaged with the ring gear. The drive unit rotatably drives the motor with the pinion being engaged with the ring gear to thereby crank the crankshaft.

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.
摘要翻译：启动安装在车辆上的发动机的起动器提供电磁螺线管以将小齿轮推向环形齿轮侧，电磁开关用于打开和关闭电动机接触点。电磁螺线管和电磁开关分别由电子控制单元即ECU控制。当怠速停止被触发时，ECU在环形齿轮旋转期间控制起动器继电器关闭，由此小齿轮与离合器通过电磁螺线管被推出到电动机的方向。结果，小齿轮与以较低转速旋转的齿圈啮合。因此，起动器的惯性质量被加到齿圈上，从而能够抑制发动机的摆动。

摘要： The brush holding device includes a brush holder having a brush-housing chamber, and a holder plate to which the brush holder is attached. The holder plate is formed with a center hole at a center portion thereof, the center hole having a size allowing a commutator to path therethrough, and a pair of elongated holes opposing to each other with respect to the opening portion, the elongated holes defining bridge portions with the opening hole. The brush holder has a thick-wall portion integral with a bottom wall of the brush-housing chamber, the thick-wall portion being formed with fitting grooves at lateral sides thereof. The bridge portions are inserted into the fitting grooves so that the brush holder is fitted to the holding plate in such a state that the thick-wall portion is caught between the bridge portions.
