PROBLEM TO BE SOLVED: To provide a collecting device of bearing lubrication grease in an underwater rotary machine capable of making use of lubrication grease for a long time effectively without waste, by automatically returning grease for the bearing side even when grease filled up in the bearing would flow down owing to the ambient thermal effect, maintaining long lifetime and stable bearing properties, and being manufactured simply in structure, low in cost, and excellent also in maintainability. SOLUTION: In the undersurface of the bearing 2 filled up with grease for lubrication, an annular spacing 6 is held on the uppersurface of a bearing bracket bottom 3u inserted with a rotary shaft 1. In the spacing 6, an operating table 7 corotating with the rotary shaft 1 is traversed directly below the bearing 2. More suitably, a tilted surface 7t with an up gradient for the rotational direction is formed on the uppersurface of the operating table 7. COPYRIGHT: (C)2004,JPO
