Abstract
An oil suction device of a vehicle has a mechanical oil pump and includes an air suction unit. The air suction unit includes a first communication passage, a second communication passage, and an opening and closing mechanism. The first communication passage communicates with an atmosphere side. The second communication passage communicates with a suction unit of the oil pump. The opening and closing mechanism is capable of switching between opening and closing of communication between the first communication passage and the second communication passage. When an oil suction pressure of the oil pump becomes a negative pressure lower than or equal to a predetermined pressure, the opening and closing mechanism is opened to cause air sucked through the air suction unit to be mixed into oil which is sucked from an oil reservoir through a suction pipe.
