Chain

Abstract

An object of the present invention is to provide a chain that is easy to assemble, has a longer life and smaller size, and allows larger tolerance for misalignment. The object is achieved by a chain including a plurality of outer links each having a pair of outer plates and pins, and a plurality of inner links each having a pair of inner plates and bushings, alternately and pivotably coupled together in the longitudinal direction of the chain by the pins rotatably inserted into the bushings, with a position restricting part positioned between each pair of the inner plates to restrict inward movement of each pair of inner plates in the chain width direction. The bushings are rotatably inserted in respective bushing holes of each pair of inner plates.
