The sealing piece 13b can be rotated even if one part (part A) is in contact with the floor surface F and the other part is cutout 13d, and flexibility is not necessarily required in the entire width. AB is used for soft flexible materials such as vinyl chloride (PVC), polyethersulfone (PES), and hard rubber.
Since it is more expensive than hard materials such as S-resin and polypropylene (PP), the use of a flexible material to unnecessary portions has caused an increase in cost.
