PROBLEM TO BE SOLVED: To provide a traction device capable of miniaturizing a bolt for fitting a traction link, easily fitting the traction link, and stopping any abnormality between the traction link and a truck frame. SOLUTION: In this traction device of a bolster-less truck for rolling stock, the force in the longitudinal direction applied between the truck and a rolling stock body is transmitted by the traction link 12 for connecting a traction frame 2 fitted to the rolling stock body 1 and the truck frame 3. Fitting parts to the traction link 12 in the traction frame 2 and the truck frame 3 are formed of gradient recessed parts 2a and 3a. A shaft part 13a at both ends of the traction link 12 is of the shape so as to be fitted in the recessed parts 2a and 3a. A traction frame side fitting part in the traction link 12 is extended in the axial direction of the traction link 12, and this extended part 12a and the truck frame 3 constitute an abnormal rise stopper. The traction link and the bolt for coupling the traction frame with the truck frame can be miniaturized, and the workability can be improved. The number of parts for constituting the abnormal rise stopper and the man-hour are not increased.
