Description
Claims (3)
- クランクシャフトが重力軸と平行となるように船体に取り付け自在なエンジンと、前記エンジンのクランクシャフトに前記重力軸の回りに回転自在に接続されるバーチカルシャフトとを備える船外機において、
前記クランクシャフトと前記バーチカルシャフトの間に前記クランクシャフトを前記重力軸と平行な方向において上方に付勢する付勢手段が設けられ、
前記付勢手段はコイルスプリングからなり、
前記コイルスプリングは、一端において前記コイルスプリングに嵌合可能な第1スプリング支持部材を介して前記クランクシャフトに接続されると共に、他端において前記コイルスプリングに嵌合可能な第2スプリング支持部材を介して前記バーチカルシャフトに接続されることを特徴とする船外機。 - 前記第1スプリング支持部材は前記コイルスプリングの外側に嵌合可能な凹部を有すると共に、前記凹部の深さは前記コイルスプリングによる上方への付勢がない状態において、前記コイルスプリングの2ピッチ以上に設定されることを特徴とする請求項1に記載の船外機。
- 前記第2スプリング支持部材は前記コイルスプリングの内側に嵌合可能な凸部を有すると共に、前記凸部の高さは前記コイルスプリングによる上方への付勢がない状態において、前記コイルスプリングの2ピッチ以上に設定されることを特徴とする請求項1または2に記載の船外機。
