| description | A low-noise chain member comprises a bushing, a roller and oil grooves in which a wedge or squeeze effect of a lubricating oil, which is interposed between the bushing and the roller, is effective in reducing noise. The oil grooves are provided on at least one of the outer surface of the bushing and the inner face of the roller. The inner face of the roller is formed with a curved surface so as to conform to the contour of a curved outer surface of the bushing. A clearance between the inner face of the roller and the outer surface of the bushing is not widened around both ends of the roller. Only a small amount of the lubricating oil between the roller and the bushing escapes to the outside, of the roller and bushing, so that a fluid lubricating state between the bushing and the roller is maintained. |
