ABSTRACT:
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.
