Abstract: An improvement in a flat type cable suspension structure which comprises a support structure comprising an upper support member and a lower support member vertically spaced from the upper support member and fixedly secured with respect to the ground, and a flat type jacketed cable extending crosswise with the support structure. The flat type cable extends downwardly through the spacing between the upper and lower support members toward said lower support member in such a manner that one face of the cable has a portion abutting against the rear side of the upper support member and the other face of the cable has a portion abutting against the front side of said lower support member. An exposed extension stemming outwardly from a tension member buried in the jacket of the cable is securely hooked over and held in a tightly suspended state on a hanger member provided on the front side of the upper support member.
