Abstract

A push-pull chain having a lock mechanism provided between inner links and outer links, which are rotatably coupled together by link pins, to thereby permit the mutual pivotal movement of both links to be restricted. The lock mechanism is provided to both links on an axial line parallel to each link pin. As a lock pin moves parallel on the axial line and it is fitted in both links, the mutual pivotal movement of the links is locked.
