<p>There is provided a seal chain in which a sealing member having a shape of + in section is steadily twisted (turned) and deformed into a shape of X and whose abrasion resistance and flexing torque are improved. The sealing member (13) is formed such that inner diametric side end faces (q) of third and fourth lip portions (13c and 13d) extending in a transverse direction from a center base portion (13e) extend in a direction orthogonal to a radial direction and outer diametric side end faces (u) thereof are formed as tapered faces such that width of said lip portion is widened from an edge face toward the base portion. A diagonal distance (z) of the center base portion (13e) is within a range of 0.8 to 1.0 of a clearance (i) between inner and outer link plates.</p> |
