To provide a weaving structure of a webbing in which a woven yarn is not projected to a surface side caused by a bending of a webbing and the phenomenon can be realized without sacrificing a strength and an energy absorbing property.
The webbing 10 is constituted by weaving a warp comprising a core yarn 16 and a ground yarn 18 and a weft. An elongation ratio of the core yarn 16 is smaller than that of the ground yarn 18 and an elongation rigidity of the core yarn 16 is larger than that of the ground yarn 18 and then a twist processing such as 'single twist' is carried out. Thereby, a convex/ concave is generated on a surface of the core yarn 16 and a friction between the core yarn 16 and other ground yarns 18 or the weft 14 is increased. The friction force between the yarns functions as a force for inhibiting a free movement of the core yarn 16 at the time of bending of the webbing 10 and it is prevented that the core yarn 16 is projected to the surface side of the webbing 10.
