Abstract
There is provided an engagement chain whose driving force per occupied space is increased, whose durability is improved by reducing stress in a direction of bending a connecting pin and whose engagement noise during driving is reduced. The engagement chain includes a large number of outer and inner link plates, each having hook-like portions, which are connected in a chain longitudinal direction by connecting pins, the large number of outer and inner link plates are connected flexibly without gap in the chain width direction while the back surfaces of the link plates opposite to the hook-like portions engage with driving sprockets.

An engagement chain including a pair of individual engagement chains which are configured so as to engage and disengage with each other, each individual engagement chain comprising:
- a plurality of outer and inner link plates, each having a hook-like portion, which are connected together in a chain longitudinal direction by connecting pins,
- wherein the pair of individual engagement chains are engaged and disengaged as the hook-like portions of each individual engagement chain engage with each other and are driven by a pair of driving sprockets which engage with a back-surface of each of the outer and inner link plates, causing the pair of individual engagement chains to engage and disengage with each other, respectively.
An engagement chain including a pair of individual engagement chains which are configured so as to engage and disengage with each other, each individual engagement chain comprising:
- a plurality of outer and inner link plates, each having a hook-like portion and a teeth portion formed on the opposite surface of the hook-like portion along with a pair of connecting pin holes,
- a plurality of connecting pins connect the outer and inner link plates together in a chain longitudinal direction by being disposed in the connecting pin holes of the outer and inner link plates,
- wherein the pair of individual engagement chains are engaged and disengaged as the hook-like portions of each individual engagement chain engage with each other and are driven by a pair of driving sprockets which engage with the teeth portion of the outer link plates, causing the pair of individual engagement chains to engage and disengage with each other, respectively.
