To provide an operational force transmission mechanism with no necessity for hydraulic seal maintenance or a feed back mechanism and capable of transmitting operational force to an operation target regardless of gyration action in a gyration type vessel propulsion device.SOLUTION: A gyration type vessel propulsion device 1 includes: a driving shaft 3; a gyration unit 4 gyrating outside a vessel with the driving shaft as the center; a propeller rotational shaft 10; and a propeller 12. An operational force transmission mechanism includes: an operation motor 31; a first pinion GS1; a first main wheel GL1 rotated by the operation motor through the first pinion; and an operational shaft 35 for rotating the first main wheel. The operational shaft 35 operates a blade angle changing device 15 of the variable pitch propeller 12.SELECTED DRAWING: Figure 1
【課題】旋回式船舶推進装置において、油圧シール保守やフィードバック機構が不要であり、旋回動作とは無関係に操作目標物への操作力を伝達できる操作力伝達機構を提供する。【解決手段】旋回式船舶推進装置1は、駆動軸3と駆動軸を中心に船舶外で旋回する旋回部4とプロペラ回転軸10とプロペラ12を備える。操作力伝達機構は、操作モータ31と、第1小歯車GS1と、第1小歯車を介して操作モータにより回転される第1大歯車GL1と、第1大歯車により回転する操作軸35を有する。操作軸35が可変ピッチプロペラ12の翼角変節装置15を操作する。【選択図】図1
