To provide an oil supply device for a marine contra-rotating propeller device and a marine contra-rotating propeller device that can supply lubricant to a contra-rotating bearing with a simple structure, reduce manufacturing cost, and suppress scattering of lubricant.SOLUTION: A marine contra-rotating propeller device 1 includes an inner propeller shaft 2. The inner propeller shaft 2 includes: a hollow part 23 formed in an axial direction to a position adjacent to a clearance 11 formed by a front side contra-rotating seal device 51 and a front side contra-rotating bearing 41 from a front end; and a plurality of oil supply ports 24 formed so as to communicate through the clearance 11 and the hollow part 23, and supplies lubricant to a bearing system including a contra-rotating bearing 4 via the hollow part 23 and the oil supply ports 24.SELECTED DRAWING: Figure 1
【課題】簡便な構造で二重反転軸受に潤滑油を供給することができ、製造コストを低減し、潤滑油の飛散を抑制することができる、舶用二重反転プロペラ装置の給油装置及び舶用二重反転プロペラ装置を提供する。【解決手段】舶用二重反転プロペラ装置1は、内側プロペラ軸2を備え、内側プロペラ軸2は、前端から前側二重反転シール装置51及び前側二重反転軸受41により形成された隙間11に隣接する位置まで軸方向に形成された中空部23と、と隙間11と中空部23とを連通するように形成された複数の給油口24と、を備え、中空部23及び複数の給油口24を介して二重反転軸受4を含む軸受系統に潤滑油を供給している。【選択図】図1
