<P>PROBLEM TO BE SOLVED: To provide a conveyer chain in which a ring-like seal member suppresses the external leakage of lubrication oil fed in a peripheral region of a roll, prevents the intrusion of a foreign matter from the outside into the peripheral region of the roll, and secures the lubrication oil over a long period of time, allowing the easy attachment of the ring-like seal member to a ring-like thrust bearing member. <P>SOLUTION: The conveyer chain 100 is provided where the ring-like seal member 180 closely attached to an outer circumference 170a of the ring-like thrust bearing member 170 and sealing the lube oil is provided between the inner periphery 130a of a roller 130 and the outer circumference 170a of the ring-like thrust bearing member 170, and a ring-like seal cover 190 attached adjacent to the outside in the chain width direction of the ring-like seal member 180 is press-engaged with the inner periphery 130a of the roller 130. <P>COPYRIGHT: (C)2013,JPO&INPIT |
