ABSTRACT:
In an engine, an oil level sensor (47) provided in a bottom part of an oil pan (15) storing engine oil so as to stand vertically upright is placed between a mutually parallel pair of balancer shafts (27, 28) housed in a balancer housing (21) provided between a lower face of a cylinder block and the oil pan (15). This not only enables the oil level sensor (47) to be placed compactly by utilizing effectively dead space formed between the pair of balancer shafts (27, 28), but also enables agitation of engine oil to be suppressed by the pair of balancer shafts (27, 28) and any degradation in detection precision due to engine oil splashing over the oil level sensor (47) to be prevented.
