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. |
