To provide a chain which can suppress a bend of a linear structure which is formed of a plurality of links by a simple constitution, and a chain drive unit.SOLUTION: A chain 13 has a plurality of links 18 which are arranged in series, and the links 18 which adjoin each other in a serial direction are connected to each other so as to be turnable. The chain is bendable to one side of a direction intersecting with the serial direction, non-bendable to the other side which is reverse to one side, and used by being advanced and contracted in the serial direction. Each link 18 has a turn regulation part 21 for regulating a turn to one side of the other engaged link 18 by being engaged with the other link 18 which is arranged ahead of two links in a progress direction Z1 when the plurality of links 18 are arranged so as to be aligned in a linear shape by being moved to the progress direction Z1, and form a linear structure 24.SELECTED DRAWING: Figure 6

    【課題】複数のリンクによって形成された直線構造体が屈曲することを簡単な構成で抑制できるチェーン及びチェーン駆動装置を提供する。【解決手段】チェーン13は、直列に配置された複数のリンク18を有し、直列方向で隣り合うリンク18同士が回動可能に連結され、直列方向と交差する方向の一方側には屈曲可能である一方、その逆の他方側には屈曲不能とされ、直列方向に進退移動させて使用される。各リンク18は、進行方向Z1に移動されることにより複数のリンク18が直線状に並ぶように配置されて直線構造体24を形成した場合に、進行方向Z1における2つ以上前方に配置された他のリンク18と係合することによって当該係合した他のリンク18の上記一方側への回動を規制する回動規制部21を備えている。【選択図】図6
