A sealing member (1) for preventing escape of micro particles, sealing a predetermined gap between a movable unit in contact with the micro particles and a housing of the movable unit, and adhered to the face of the movable unit or housing without impeding movement of the movable unit, based on a pile fabric configured with a pile yarn forming a sliding flock (3) and a base cloth (2) of plain woven tissue supporting the pile yarn, the pile yarn of the flock (3) being formed of a high strength polyethylene fiber having a filament fineness of 0.1-6.0 dTex, a fiber cross section oblateness of at least 1.1, and an average tensile strength of at least 22 cN/dTex, and the flock (3) having a height of 1.5-4.0 mm, a pile density of 13,000-346,000 filament/cm<2> at the pile yarn portion, and a pile yarn cross section area of 0.02-0.2 cm<2> per 1cm<2> of the base cloth. The sealing member (1) includes a coating layer (5) at the back side of the base cloth (2) to prevent fall off of the flock (3), and is superior in slidability and abrasion resistance. <IMAGE> |
