Abstract

PURPOSE:To improve waterproofing effectiveness by providing water barriers across the grooves formed between annular lines of projection formed on the seal surface of packing. CONSTITUTION:The packing 6, which is inserted between the installation surface 2 of instrument and the installation surface 4 of the equipment 3, it a near square frame of annular rubber, etc. Lines of projection 8 are formed on one surface 7 of the packing, which is in contact with the installation surface 2 of instrument 1 positioned so that the lines touches inside the installation surface 2. On the other surface 9, which is in contact with the installation surface 4 of equipment 3, a multiple number of annular lines of projection 10 running parallel with the edge line are provided, and water burries 12 are formed across the grooves 11 between the projected lines at location with a conner between them; water barriers to divide the grooves 11 into insolated sections.
