PROBLEM TO BE SOLVED: To enable a rotation angle of a rotation link to be easily increased while miniaturizing an actuator, to be a driving source of a plurality of vanes, by controlling a movable amount thereof.SOLUTION: A cooling device for a unit swing type internal combustion engine comprises: a plurality of vanes 101 to 103 which open and close a cooling air inlet port 63; an actuator to be a driving source of the vanes 101 to 103; and a power transmission mechanism 105. The actuator 104 is arranged with a shaft line L3 of an output shaft thereof parallel to the shaft line L1 of a crank shaft 71. The power transmission mechanism 105 has: a first link 126 which rotates around a support shaft 61J depending on movement of the output shaft; rotation links 121 to 123 which rotate the vanes 101 to 103; and a connection member 125 which integrally rotates the vanes 101 to 103. Power of the actuator 104 is transmitted to the connection member 125. A rotation angle θB of the rotation links 121 to 123 is larger than the rotation angle θC of the first link 126.SELECTED DRAWING: Figure 5

    【課題】複数の羽板の駆動源となるアクチュエータの可動量を抑えてアクチュエータを小型化しながら、回動リンクの回動角度を大きく確保し易くする。【解決手段】冷却風取入口63を開閉する複数の羽板101〜103と、前記羽板101〜103の駆動源となるアクチュエータ104と、動力伝達機構105とを備え、前記アクチュエータ104は、その出力軸の軸線L3が前記クランク軸71の軸線L1と平行に配置され、前記動力伝達機構105は、前記出力軸の移動に応じて支軸61Jを基準に回動する第1リンク126と、前記羽板101〜103を回動させる回動リンク121〜123と、前記羽板101〜103を連動して回動させる連結部材125とを備え、前記アクチュエータ104の動力は、前記連結部材(125)へ伝達され、前記第1リンク126の回動角度θCよりも前記回動リンク121〜123の回動角度θBが大きい。【選択図】図5
