In an engine oil pump, the lubricating oil in the suction chamber is forced to be delivered to the discharge side by the rotation of both gears. An engine oil pump characterized in that the width in the sliding direction of the sliding surface between the side surface of the gear and the pump casing is approximately twice the pitch of the gear.
