Abstract
A starter-motor mounting structure is provided in a wall of an engine case, in which a front mounting boss is formed in a rear inclined surface of an inclined cylinder block portion that projects from a crankcase. A rear mounting boss is formed in a front wall surface of a raised portion where an upper wall of a transmission case is raised upwardly to accommodate a main shaft that is positioned higher than a counter shaft. The front mounting boss and the rear mounting boss are offset from each other in the crankshaft direction. Front and rear brackets of a starter motor are fastened to the front mounting boss and to the rear mounting boss, respectively. This arrangement enables a starter motor to be securely mounted to a power unit case with high rigidity, while enabling a reduction in the size of the internal combustion engine.
