A side of the flange (4) and segments of the plate are arranged in vertical guide rails (5). The guide rails are mounted on sides of a door and the cover plate. Two sealing parts (6, 7) are vertically arranged in a resilient gasket (8), where the resilient gasket is adhered to a surface of the plate. Interior sides of the vertical guide rails are formed on the sealing parts, which are located outside the guide rails. The resilient gasket is made of rubber.</p> |
