Abstract
An oil level sensor for detecting an oil level is arranged in an engine oil pan. The oil level sensor includes a mounting section and a sensing section. An air hole is formed at an upper end of a cover member of the sensing section. The air hole is surrounded by a tubular portion of a shield member attached to a baffle plate of the oil pan. Therefore, any splashed engine oil in the oil pan is restricted from entering the cover member of the sensing section through the air hole. Also, a clearance (α) for venting air is formed between the tubular portion and the baffle plate.
