The present invention relates to an oil supply structure of a descending device installed on the outer wall of a building. The oil supply structure of the descending device comprises: a base plate (100) which has a drive gear shaft (110) and a driven gear shaft (120) vertically corresponding to each other; a drive part (200) which has a rope rotating part (210) and a drive gear (220); a speed reducing part (300) which has a driven gear (310) gearing with the drive gear (220), multiple brake pads (330), and an oil path (U) to properly control the frictional force of the brake pads (330); and a lubricant storage part (400) which has a certain storage space (410) and an outlet (420) to supply a lubricant (G) from the storage space (410) to the drive gear (220) or the driven gear (310). Therefore, the present invention continuously supplies the lubricant for a long time by forming the lubricant storage part to supply the lubricant on one end of the drive gear shaft or the driven gear shaft. |
