Title: Lubricant sealing structure for gear coupling

Abstract: Disclosed is a lubricant sealing structure for a gear coupling, which can firmly prevent the leaking of the lubricant due to vibration or the like in the axial and radial directions inside the gear coupling. A sealing member is a cloth-inserted rubber 21 having flexibility. The cloth-inserted rubber 21 has a first end being fixed to a fixing member 24s on a cover plate 20 mounted on a side of an outer ring 7 and a second end being fixed to another fixing member 25s on a side of the drive shaft 10 in liquid tight manner in the axial direction of a drive shaft 10. Each of the first and second ends of the cloth-inserted rubber 21 has a face extending in a direction that is perpendicular to the axial direction. The cloth-inserted rubber 21 seals the lubricant at the face of said each of the first and second ends.
