    摘要: A gland packing includes a gland packing body made of expanded graphite. The gland packing body has a cylindrical shape, and has a plurality of layers formed in a radial direction. The gland packing body has first and second surfaces, which are both end surfaces in an axial direction. The gland packing further includes an annular first sheet portion made of expanded graphite, an annular second sheet portion made of expanded graphite, an annular first porous member, and an annular second porous member. The first sheet portion is arranged on the first surface. The second sheet portion is arranged on the second surface. The first porous member is arranged on the first sheet portion. The second porous member is arranged on the second sheet portion.
