<p>A connection structure of a chain for transportation, comprising a connection lever (2) projectedly installed at one end of a block link (A) in transporting direction, a recessed connection part (5) recessedly provided at the other end, a pair of annular bush supports (25) and (30) installed in the recessed connection part (5), and a spherical bush (20) fixed to the connection lever (2) and disposed between the pair of annular bush supports (25) and (30), wherein one annular bush support (25) comes into slidable contact with the spherical bush (20) near one end thereof in transporting direction, and the spherical recessed surface (31) of the other annular bush support (30) comes into slidable contact with the spherical bush (20) near the other end in transporting direction, whereby a rattling can be prevented from occurring at connection parts to suppress pulsation and noise, the block links can be smoothly swung each other and rotated in normal and reverse directions each other, a structure can be simplified, rigidity and durability can be increased, disassembly and assembly can be easily performed even in a restricted space, a maintenance can be performed easily, a working time for assembly and disassembly and maintenance can be reduced, handling can be performed easily, a size can be easily reduced, a mass-production can be adopted, and also a cost can be reduced for economy.</p> |
