摘要：A rope traction device includes a sheave (20) having an annular rope receivinggroove (23) and being driven and rotated with a traction rope (22) received in the ropereceiving groove to cause the traction rope to be wound on the sheave and the ropetraction device thereby moves along the traction rope. The sheave includes a pair of sidewalls (24, 24) made of an elastic material and formed integrally with the sheave forforming the rope receiving groove. The interval between inner surfaces of the side walls(24,24) in a rope holding portion is made smaller than the diameter of the traction ropeby a predetermined value. The rope receiving groove may be formed in a U-shapedsection, a V-shaped section of a section which is a combination of the U-shaped sectionand the V-shaped section.
