In an engine, an oil level sensor (47) provided at the bottom of an oil p an (15) that contains engine oil and upstanding upward in the vertical direc tion is placed between a pair of balancer shafts (27, 28) that are received in parallel to each other in a balancer housing (21) provided between the lo wer surface of a cylinder block and the oil pan (15). A dead space formed be tween the pair of balancer shafts (27, 28) is effectively used to allow the oil level sensor (47) to be compactly received. Also, the pair of balancer s hafts (27, 28) suppress agitation of the engine oil to prevent degradation o f detection accuracy caused by splash of the oil on the oil level sensor (47 ).
