摘要： A vehicular power unit including a drive-side transmission sprocket wheel provided on an end of an output shaft that protrudes from one side of a crankcase, an endless transmission belt for transmitting power to a driving wheel wound the sprocket wheel. The endless transmission belt transmits power from the crankshaft to a transmission housed in the crankcase. A water pump is arranged on the same side of the crankcase in a position between the crankshaft and the output shaft. Further, the water pump is disposed inside the drive-side transmission sprocket wheel in a direction along the axis of an output shaft. This configuration enables the vehicular power unit to be formed in a compact size in a direction along an axis of a crankshaft.

摘要： 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.

摘要： A starter motor and balancers are disposed reasonably so as not to interfere with each other by effectively utilizing spaces in an engine. Cylinders are set so as to be tilted forward on casings supporting a crankshaft in a transverse position, a rear balancer and a starter motor are disposed in a space behind the cylinders, and a front balancer is disposed on an opposite side of the rear balancer with respect to the crankshaft. The rear balancer and the front balancer are disposed on the right side of a plane including the center of gravity of the engine and perpendicular to the crankshaft, and the starter motor is disposed on the left side of the plane. Weight portions included in the rear balancer and the front balancer are disposed close to the plane to prevent coupling vibrations.
