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.
摘要翻译：获得的是具有如下结构的发动机起动器，其中即使当由于辊和离合器内部相互滑动而在辊上产生摩擦热时，通过抑制辊的滚动接触表面的变形而减小由于摩擦热而导致辊的滚动接触表面的硬度，从而可以改善从离合器外部到离合器内部的旋转力的传递。发动机起动器包括用于将输出轴（4）的旋转力传递到小齿轮（7）的离合器（5），离合器外部（10），离合器内部（11），其一端部面向内部离合器外部（10）和固定有小齿轮（7）的另一个端部，以及在离合器外部（10）和离合器内部（11）之间设置的辊（12）。离合器外部（10）形成为具有锥形形状的切口部（10a）。切口部（10a）形成有抵靠辊（12）的锁定部（10b）。对辊（12）的滚动接触表面进行碳氮共渗处理。
