Abstract
A starting device for a general-purpose engine according to one embodiment includes: a starter motor; a pinion gear mounted on an output shaft of the starter motor; a camshaft gear mounted on a camshaft; a crankshaft gear mounted on a crankshaft and meshing with the camshaft gear; and a gear assembly configured to transmit a driving force of the starter motor via the pinion gear to the camshaft gear and configured not to transmit a driving force of the camshaft gear to the pinion gear. The pinion gear, the camshaft gear, the crankshaft gear, and the gear assembly are disposed in a crankcase in a state where the pinion gear meshes with a gear included in the gear assembly.
