PROBLEM TO BE SOLVED: To provide a cooling device for a unit swing type internal combustion engine capable of easily securing a bank angle of a vehicle.SOLUTION: A cooling device for a unit swing type internal combustion engine includes: a fan cover 61 in which a cooling air intake port 63 for taking in the outside air is formed; a movable louver 100A which opens/closes the cooling air intake port 63 by a first vane 101, a second vane 102, a third vane 103 rotating around a first rotary shaft 111, a second rotary shaft 112, a third rotary shaft 113 provided at the cooling air intake port 63 of the fan cover 61; and a power transmission mechanism 105 for transmitting the power from an actuator 104 to the movable louver 100A. In a vehicle side view, an axis line of a rear wheel axle is in a position lower than an axis line of a crank shaft, and the first rotary shaft 111 to the third rotary shaft 113 are supported by the fan cover 61 by the axis lines 111C, 112C, 113C being oriented in the longitudinal direction of the vehicle. The power transmission device 105 is connected to the front part of the first rotary shaft 111 to the third rotary shaft 113, and provided in front of the cooling air intake port 63.SELECTED DRAWING: Figure 3
【課題】車両のバンク角を容易に確保可能なユニットスイング式内燃機関の冷却装置を提供する。【解決手段】外気を取込む冷却風取入口63が形成されたファンカバー61と、ファンカバー61の冷却風取入口63に設けられた第1回転軸111、第2回転軸112、第3回転軸113を中心に第1羽板101、第2羽板102、第3羽板103が回動して冷却風取入口63を開閉する可動ルーバー100Aと、アクチュエータ104からの動力を可動ルーバー100Aへ伝達する動力伝達機構105と、を備え、車両側面視で、クランク軸の軸線よりも後輪車軸の軸線の方が低い位置となり、第1回転軸111〜第3回転軸113は、その軸線111C,112C,113Cが車両の前後方向に指向されてファンカバー61に支持され、動力伝達機構105が、第1回転軸111〜第3回転軸113の前部に連結されて冷却風取入口63の前方に設けられる。【選択図】図3
