Abstract

PURPOSE:To enhance sealing performance of a seal and lessen the coefficient of friction at a sliding portion by making peripheral seal lip on the sliding side to contain powdered fluorine resin. CONSTITUTION:Packing is formed of an annular body which has an outer peripheral lip 5 and an inner peripheral lip 6 extending from an axial end of a base 2 with a rectangular cross-section along a slightly slant legs of a U shaped cross section. And, this packing base material 4 is made of polyurethane rubber material, and powdered four flouride ethylene resin 3 is contained only in the outer periphery of packing.
