An elastic cable structure includes an elastic cable. The elastic cable includes a plurality of strands of elastic tubes, and the strands of elastic tubes are twisted mutually. Each of the elastic tubes includes an outer layer and a plurality of latex bars mounted in and covered by the outer layer. Thus, the latex bars are covered by the outer layer so that the latex bars will not directly contact the users skin and will not cause allergic reactions to the user. In addition, the latex bars are completely covered by the outer layer so that when the latex bars are broken due to an excessive force, the latex bars are restricted by the outer layer and will not be sprung outward.
