A vehicle engine, particularly adapted for motorcycle application, includes a housing structure in which the cylinder block, the crankcase and the transmission case are integrally formed and openings are provided in separate, angularly displaced walls of the housing for accessing the crankcase and transmission case respectively to permit the crankshaft and the transmission to be independently installed or demounted with respect to each other. Also, the detachable cover for closing one of the side openings of the housing is formed as a stopper for preventing axial disengagement of the starter apparatus ring gear from the crankcase. |
