Abstract
An engagement chain in which a buckling strength of a pair of engagement chains engaged with each other is improved without blocking engagement operations between inner tooth plates and between outer tooth plate. The chain includes inner tooth plates, bushes, outer tooth plates and connecting pins. Buckling limiting flat surfaces of adjoining plates are brought into surface contact with each other when opposing segments of the chain are integrated together by driving sockets.
