PURPOSE: An air pressure removal device of an oil level gauge guide is provided to exactly measure a flow of oil by an oil level gauge by forming an air hole for removing air pressure to a combining boss to which the oil level gauge guide is combined. CONSTITUTION: A combining boss(7) is formed to the upper end of a side of an oil pan(1) and the end portion of a level gauge guide(2) in which a level gauge(4) is inserted is inserted and combined into the combining boss. An air hole(10), penetrating the level gauge guide from the inside of the combining boss, is formed to remove compressed air pressure when the level gauge is inserted into the level gauge guide. The air hole is formed at a position higher than the height of the maximum oil level of the oil pan.
