PROBLEM TO BE SOLVED: To solve the problem in which, for example, a structure capable of more reliably preventing oil leakage from a hoist is desired in a prior art.SOLUTION: A hoist oil leakage prevention structure comprises an auxiliary member and an adhesion member. The auxiliary member is disposed between a bearing section supporting a driving shaft of a hoist and a detector being provided at an exposed end portion of the driving shaft and detecting a rotational speed. The adhesion member is interposed between the auxiliary member and an end portion partition wall and adheres thereto. The adhesion member is formed along an outer peripheral surface of the exposed end portion and has an opening at a lower side in a vertical direction. The auxiliary member has an absorption member holding section and an annular space portion. The absorption member holding section is brought into contact with the outer peripheral surface of the exposed end portion and holds an absorption member capable of absorbing oil adhering to the exposed end portion annularly provided. The annular space portion is formed with an opening communicating with an annular space at a lower side of the annular space in the vertical direction while being formed with the annular space along the outer peripheral surface of the exposed end portion.

    【課題】従来技術においては、例えば、より確実に巻上機からの油漏れが防止できる構造が望まれている。【解決手段】実施形態の巻上機油漏れ防止構造は、補助部材と、密着部材とを備える。補助部材は、巻上機の駆動軸を支持する軸受部と駆動軸の露出端部に設けられ回転速度を検出する検出器との間に配置される。密着部材は、前記補助部材と端部隔壁との間に介在して密着する。前記密着部材は、前記露出端部の外周面に沿って形成され鉛直方向下側に開口を有する。前記補助部材は、吸収部材保持部と、環状空間部とを有する。吸収部材保持部は、前記露出端部の外周面に接触して環状に設けられ前記露出端部に付着した油を吸収可能である吸収部材を保持する。環状空間部は、前記露出端部の外周面に沿った環状空間が形成されると共に前記環状空間の鉛直方向下側に当該環状空間と連通する開口が形成される。【選択図】図3
