第(1)項記載のエンジンの始動装置。[Scope of claims for utility model registration] (1) A starter gear provided on a starter shaft,
By meshing an idle gear provided on an idle shaft and meshing the idle gear with a driven gear provided on a crankshaft and rotating the starter shaft, the crankshaft is rotated through each gear. In a starting device for an engine, the engine is rotated at startup, a one-way clutch is interposed between the idle shaft and the idle gear, and the idle shaft is disposed in a crankcase so as to be freely rotatable. is provided with a torque limiting mechanism, and the torque limiting mechanism disables the rotation of the idle shaft under normal conditions, and also causes a torque exceeding a set value to be applied to the idle shaft in a direction opposite to the rotational direction of the idle gear at the time of starting. 1. A starting device for an engine, characterized in that the idle shaft is allowed to rotate when the idle shaft is turned on. (2) The torque limiting means includes a slide member disposed in the idle shaft bearing portion of the crankcase so as to be movable but non-rotatable along the axial direction of the idle shaft, and the slide member and the idle shaft bearing portion. Utility model registration claim No. 1 is characterized in that it comprises a spring interposed between the slide member and the idle shaft to bring the slide member into contact with the idle shaft, and a front cam means provided between the slide member and the idle shaft. ) The engine starting device described in item ).
