PROBLEM TO BE SOLVED: To accelerate warming-up during cold starting.SOLUTION: A cooling apparatus of a scooter type motorcycle mounting a unit swing type internal combustion engine includes: a fan cover (50) covering a cooling fan (40) and forming a cooling air intake (53) for taking in outside air; and a movable louver (60) attached to the cooling air intake (53) of the fan cover (50) and capable of opening/closing the cooling air intake (53) by rotating blades (61) around support shafts (62) parallel to an open surface of the cooling air intake (53). In the cooling apparatus of the unit swing type internal combustion engine, a movable louver frame body (55) for directing the support shafts (62) in the front-back direction of a vehicle and pivoting the support shafts (62) and a link storage part (54s) formed on the back of the movable louver frame body (55) are formed on the fan cover (50), and a link mechanism (70) for rotating the blades (61) is stored in the link storage part (54s). |
