An engine 20 includes a two-plane type crankshaft 30 and a balancer shaft 50 for reducing a primary couple of the balancer shaft 50. The crankshaft 30 includes a crankshaft body 30a and a first gear 38. The first gear 38 is disposed at one axial end side of a first crank web pair 31a disposed at the outermost one axial end side of the crankshaft 30. In the engine 20 including the two-plane type crankshaft, the weight of the engine can be reduced while securing high reliability.
