Synthetic fiber rope which has lightweight, high tensile strength and flexibility is receiving a lot of attention as the replacement for stainless steel wire rope. This study is clarifying various physical characteristics of synthetic fiber ropes to design tendon-driven mechanism and this paper take note of durability of repeated bending. We performed an experiment with two synthetic fiber ropes and one stainless steel wire rope in conformity with Japanese Industrial Standards. As a result, stainless steel wire rope and one synthetic fiber rope which has high resistance to frictional wear didn't get loss of tensile strength, however, repeated bending causes the tensile strength deterioration of the other synthetic fiber ropes which is weak in frictional wear.
