Abstract
An internal combustion engine includes a crankcase, a case cover for covering a side of the crankcase, a crankshaft and a balancer shaft. A balancer has a balancer driven gear and a balance weight provided on the balancer driven gear and is acted upon and driven by a driving force of the crankshaft to rotate. An oil pump is accommodated in the crankcase and has an oil pump driving shaft disposed in parallel to the crankshaft and the balancer shaft. The oil pump includes a pump driven gear. The balancer has a pump driving gear which has a diameter smaller than that of the balancer driven gear and rotates together with the balancer driven gear. The pump driving gear meshes with the pump driven gear. The oil pump driving shaft is disposed within a range of rotation of the balance weight as viewed in an axial direction thereof.
