1. An industrial fabric in which an upper surface side fabric and a lower surface side fabric are bound,
wherein the upper surface side fabric and the lower surface side fabric are formed by interweaving warps and wefts,
wherein the wefts include:
binding wefts that bind the upper surface side fabric and the lower surface side fabric;
upper surface side wefts that form a part of the upper surface side fabric; and
lower surface side wefts that form a part of the lower surface side fabric;
wherein the warps include:
binding warps that bind the upper surface side fabric and the lower surface side fabric;
upper surface side warps that are interwoven with the upper surface side wefts without being interwoven with the lower surface side wefts so as to form a part of the upper surface side fabric; and
lower surface side warps that are interwoven with the lower surface side wefts without being interwoven with the upper surface side wefts so as to form a part of the lower surface side fabric,
wherein each of the upper surface side warps arranged vertically with the lower surface side warps so as to form pairs has a common weaving pattern excluding the binding wefts,
wherein the binding warps constitute at least one of two of the warps vertically arranged forming pairs,
wherein in the pairs formed by the binding warps and the warps arranged vertically with the binding warps, the binding warps and the warps complement each other so as to form a weaving pattern for one upper surface side warp and a weaving pattern for one lower surface side warp, respectively,
wherein the upper surface side warps and the binding warps are interwoven with the upper surface side wefts so as to form the upper surface side fabric formed in a predetermined weaving pattern for each warp row,
wherein the lower surface side warps and the binding warps are interwoven with the lower surface side wefts so as to form the lower surface side fabric formed in a predetermined weaving pattern for each warp row, and
wherein the binding wefts form knuckles that pass above two or less of the upper surface side warps consecutively and are not adjacent to one another in the warp direction.
