Zusammenfassung:	FIELD: sports equipment. SUBSTANCE: running track has rolls pressed into flexible couplings and belts. Upper and lower layers of each coupling and upper layer of each belt are manufactured from resilient friction material. Middle layer is made from porous resilient material and lower layer of each belt is made from resilient antifriction material. Working belts are laid onto roll couplings. Bars of break contact are positioned in windows of upper lateral horizontal surfaces of upper base. Break contact casings rest upon lower horizontal surface of upper base and fixed thereon. Each outer neck of supporting rolls is located in force transformation unit and each inner neck of supporting rolls is located in orienting unit. EFFECT: enhanced reliability in operation and increased service life. 4 dwg
