Anti-skid device of a kind that includes a chain-provided pulley that on use if brought to contact with the side of the vehicle wheel so that when the vehicle wheel is rotated the chain pieces (2) are successively thrown in between wheel and ground in order to improve the traction. The anti-skid device is rotatably journaled in an arm (7) that in turn is fastened to a housing (8) that is turnably journaled on a stub axle (9). The turning movement of the arm and the housing is achieved in one direction by a bowden wire (20) and in the other dirction by a return spring (23). The stub axle (9) of the housing (8) is fastened to a plate (10) that in turn is fastened to a tube (11) by means of welding. The tube (11) is in turn arranged in clamps (12 and 13), that in turn are fastened to the bolts holding together the vehicle axle and its spring. Since the fastening tube (11) is held in clamps (12 and 13) the device according to the invention can be displaced lengthwise of the vehicle as well as it can be given different movement paths between parking and working position by turning the tube (11) in the clamps (12 and 13). In this way a step-by-step adjustment of the working position of t…
