<P>PROBLEM TO BE SOLVED: To provide a wind power generation device having improved maintenance efficiency by allowing easy work for filling grease into a bearing supporting the turning shaft of a nacelle. <P>SOLUTION: The wind power generation device comprises the windmill 2, a generator 4 connected to a main shaft 3 of the windmill 2, the nacelle 5 for storing the generator 4, etc., and a tower 6 for turnably supporting the nacelle 5 with the turning bearing 42. In this case, it has a plurality of grease filling parts 42d for the turning bearing 42. The grease filling parts 42d are communicated with one grease filling port 11c via a hose 48, and the grease filling port 11c is arranged on one of the right and left sides of the nacelle 5. Thus, the grease can be collectively filled into the plurality of grease filling parts through one grease filling port, resulting in easy work for lubricating the turning bearing. <P>COPYRIGHT: (C)2007,JPO&INPIT |
