<p>The invention discloses a sealing chain, which can appropriately ensure the contacting pressure between a first lip part (13a) of a sealing component (13) and a plate, inhibits the unevenness of the contacting pressure even when the sealing chain is obliquely erected and the sealing compression amount becomes uneven, and eases the stress concentration of each lip part (13a, 13b, 13c, 13d) under the state that the sealing component (13) is compressed. The first and second lip parts (13a, 13b) extending along a radial direction from a central base (13e) are characterized in that the widths (C, A) of the radial middle parts are larger than the width (B) of the third and the fourth lip parts (13c, 13d); a necking part (13f) having a width being smaller than the radial middle part is disposed at the radial base end; the necking part (13f) is provided with a bending recessed surface (13h).</p> |
