Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a partition which is not moved because paper cloth manufactured of paper twines has elasticity in the thickness direction and is held under a state that it is compressed slightly, and has a taste having a texture because there are irregularities in the thickness direction of the paper cloth. SOLUTION: In the partition, which has edge frame materials formed in square-shaped outer edges and parting boards installed inside the edge frame materials and in which vent holes penetrated to surfaces and rears are formed to the parting boards, the parting boards are composed of two boards, which are arranged while the peripheries of the vent holes are opposed to each other, while an insect-repellent board composed of the paper cloth manufactured of the paper twines braided between these two parting boards is held in an unmovable manner, and the insect-repellent board is closed by the paper cloth.
