Abstract
To provide a sealed chain joint structure that connects both ends of the sealed chain by fitting a seal ring concentrically around a pin in a gap formed between an inner plate of an inner link and an outer plate of an outer link, in which a coupling plate can be easily installed using ordinary tools. A coupling link joins together inner links of both ends, a coupling pin passed through a bush hole projects from the outer plate, a tip portion of the coupling pin is a stepped tip portion of reduced diameter, and a ring groove is formed in an outer periphery of the stepped tip portion. A separate seal ring is fitted to the ring groove and the stepped tip portion protruding from an opposite side of the inner link is inserted into a hole to mount the coupling plate, and a clip engages a clip groove formed in the tip of the stepped tip portion and installed.
