Abstract
In a seal chain, a seal mechanism comprises a pair of mutually facing seal members, a first seal member of the pair being in contact with an inner plate of the chain, and a second seal member of the pair being in contact with an outer plate of the chain. A pair of resilient annular lips formed on the first seal member are in sliding contact with a surface of the second seal member. Each sealing member has lubricant-filled grooves facing the plate with which it is in contact.
