Abstract: There is disclosed a woven webbing structure, which resists interwoven yarns from coming out from the surface of the webbing due to bending, or the like. This is achieved without any significant reduction in the strength or energy absorptivity of the webbing. The webbing includes warps that each have a cored yarn and a side yarn, and wefts interwoven therein. The cored yarn is set such that the elongation percentage thereof is smaller than, or the extensional rigidity thereof is larger than, that of the side yarn, and is twisted by single twisting or the like. As a result, unevenness is formed on the surface of the cored yarn and friction between the cored yarn and other yarns, that is, the side yarn or the weft increases. The frictional force between yarns functions for resisting free movement of the cored yarn due to bending of the webbing, thereby making it possible for the cored yarn to resist coming out from the surface of the webbing.
