A first pinion gear fit to the rotation member through a first serration unit rotates with, and also moves with the rotation member if the pinion gear unit moves towards an engagement location with an engine starting gear. A second pinion gear is fit to the rotation member adjacent to the first pinion gear through a second serration unit, rotates with and moves with the rotation member if the pinion gear unit further moves towards the engagement location, and engages with the starting gear later than the first pinion gear, where the first pinion gear engages with the engine starting gear. Fitting is performed by the first and second serration units so that phases of teeth of the first and second pinion gears in a circumferential direction correspond with each other.

摘要： Provided is an engine starter wherein a torsional angle θ1 of a helical spline 4a of an output shaft 4 is set in such a way that a reactive force Fp1 of a plunger spring 33, which is operated to a clutch 5, is larger than a propulsive force F, which is operated so as to urge the clutch 5 by a rotational force of the motor 2 in a shaft direction along a helical spline 4a of an output shaft 4, before a pinion engaging solenoid 8 is operated. Thereby, it can be prevented that the clutch 5 is urged in the shaft direction, so that it can be prevented without upsizing the engine starter that the pinion 6 is protruded in the shaft direction.

摘要： Obtained is an engine starter having a structure in which, even when frictional heat is generated on a roller due to sliding of a roller and a clutch inner with respect to each other, deformation of a rolling contact surface of the roller is reduced by suppressing reduction in hardness of the rolling contact surface of the roller due to the frictional heat, thereby making it possible to improve transmission of a rotation force from a clutch outer to a clutch inner. The engine starter includes a clutch (5) for transmitting a rotation force of an output shaft (4) to a pinion gear (7), a clutch outer (10), a clutch inner (11) having one end portion facing an inner portion of the clutch outer (10) and another end portion to which the pinion gear (7) is fixed, and a roller (12) which rolls while being provided between the clutch outer (10) and the clutch inner (11). The clutch outer (10) is formed with a notch portion (10a) of a tapered shape. The notch portion (10a) is formed with a lock portion (10b) abutting the roller (12). A rolling contact surface of the roller (12) is applied with carbonitriding treatment.
