The root parts of the piles (40) are fixed between the back knitted fabric (22) and the sheet member (30). A gap between connecting fibers (23) comprises a discharge flow path (24) of fluid having entered from the front knitted fabric (21). A through-hole (31) penetrating from the back knitted fabric (22) to the sheet member (30) is provided.SELECTED DRAWING: Figure 1 |
