    • PROBLEM TO BE SOLVED: To make a pinion of a starter quietly bite in a ring gear of an engine when the engine is on the way to a stop and during the engine is still rotated.SOLUTION: In a system for deciding the jump-in timing of the pinion while detecting rotation speeds of the ring gear and the pinion by a sensor after previously rotating the starter during the stop of the engine when the engine is stopped by an idling stop operation, a reverse rotation speed which is defined by a constitution of a helical spline and the jump-in speed of the pinion is subtracted from the rotation speed of the pinion which is defined from the rotation speed of a motor, calculation is performed so that the pinion and the ring gear contact with each other, the start of the energization of a magnet switch is decided at a time point at which an error between a rotation speed which is obtained by converting the rotation speed to the rotation speed of the ring gear by using a reduction ratio between the pinion and the ring gear, and the rotation speed of the ring gear becomes 180 rotations per minute or lower, and the jump-in operation of the pinion is performed.

    • PURPOSE:To make it possible to reduce the force for driving a crank shaft upon starting, by providing a reverse rotation inhibiting mechanism of one-way ratchet type, etc. in order to prevent the crank shaft from reversely rotating. CONSTITUTION:Upon stopping of an engine, a crank shaft 1 is rotated by several rotations by inertia, and when compression stroke is turned to be effective, the crank shaft is stopped just before the top dead center due to the compression resistance of the stroke. Due to the reaction force of the compression, the force for reverse rotation is effected, and is transmitted to a starter driven gear 7, idle gears 11, 10, etc. However, a ratchet pawl inhibits the drive idle gear 10 from reversely rotating, and therefore, the crank shaft 1 will not reversely rotate. Compressive pressure leaks through the gap between a piston and a cylinder during a long time of stopping in this condition, so that the pressure becomes equal to the atmospheric pressure. Accordingly, upon starting of the engine the remaining stroke of compression stroke is short so that the engine may be smoothly started to miniaturize a cell motor 12.
    • 目的:通过提供单向棘轮式等的反转禁止机构,能够减小起动时的曲柄轴的驱动力,以防止曲轴反转。 构成:在发动机停止时,曲轴1通过惯性旋转几圈,当压缩行程变为有效时,由于行程的抗压性,曲轴在上止点之前停止。 由于压缩的反作用力,反作用力被实现,并且被传递到起动器从动齿轮7,空转齿轮11,10等。然而,棘爪禁止驱动空转齿轮10反向旋​​转, 因此曲柄轴1不会反向旋转。 在这种情况下长时间停止时,压缩压力通过活塞和气缸之间的间隙泄漏,使得压力等于大气压力。 因此,在发动机起动时,压缩行程的剩余行程较短,使得发动机可以平稳地起动以使电池电动机12小型化。

    • PROBLEM TO BE SOLVED: To prevent increase of a static friction coefficient in an impact absorbing interface 53 by suppressing hindrance of sliding of molybdenum disulfide caused by absorbing moisture and oil in an impact absorbing device 1 provided in a starter.SOLUTION: An impact absorbing device 1 includes a seal member 54 for sealing the inside of an impact absorbing interface 53 with respect to the outside. Thus, intrusion of fluid into the impact absorbing interface 53 can be suppressed, and absorbing of both of moisture and oil of molybdenum disulfide existing in the impact absorbing interface 53 can be suppressed. Accordingly, hindrance of sliding of the molybdenum disulfide caused by absorbing the moisture and the oil can be suppressed, and increase of a static friction coefficient in the impact absorbing interface 53 can be prevented.
