摘要：A rope traction device includes a sheave having an annular rope receivinggroove and being driven and rotated with a traction rope received in the rope receivinggroove to cause the traction rope to be wound on the sheave and the rope tractiondevice thereby moves along the traction rope. The sheave includes a pair of side wallsmade of an elastic material and formed integrally with the sheave for formaing the ropereceiving groove. The interval between inner surfaces of the side walls in a rope holdingportion is made smaller than the diameter of the traction rope by a predetermined value.The rope receiving groove may be formed in a U-shaped section, a V-shaped section or asection which is a combination of the U-shaped section and the V-shaped section.
