To improve a time period more than before, in which flight is possible in an emergency where a lubrication oil is not supplied to a transmission through a lubrication system from the outside during flight of a helicopter.SOLUTION: A transmission lubricating structure of a helicopter comprises: a transmission having a transmission mechanism that shifts a speed of rotational power inputted from a motor and outputs the shifted rotational power, and a housing that accommodates the transmission mechanism; and a lubrication device that lubricates the transmission mechanism. The lubrication device includes a capturing part that captures lubrication oil mist in an internal space of the housing, and a dripping part that is disposed below the capturing part and drips droplets of lubrication oil, which are formed by the captured mist collecting under the mist's own weight, into the transmission mechanism.SELECTED DRAWING: Figure 1

    【課題】ヘリコプターの飛行中に潤滑油が外部から潤滑系統よりトランスミッションに供給されない非常時の飛行可能時間を、従来よりも向上させる。【解決手段】ヘリコプターのトランスミッション潤滑構造は、原動機から入力される回転動力を変速して出力する変速機構と、変速機構を収容するハウジングと、を有するトランスミッションと、変速機構を潤滑する潤滑装置と、を備える。潤滑装置は、ハウジングの内部空間で潤滑油のミストを捕集する捕集部と、捕集部の下側に配置され且つ捕集されたミストが自重で集合して形成された潤滑油の液滴を変速機構に滴下する滴下部とを有する。【選択図】図1
