|20150065281||CHAIN STRUCTURE - An object of the present invention is to provide a chain structure which has a simple construction and can prevent a chain from being detached from a gear tooth of a sprocket wheel due to a great wave force and prevent the chain and a flight plate from dropping so as to break members of the chain and the flight plate and the other portions of the chain structure.||03-05-2015|

|20110136606||CHAIN-SPROCKET MECHANISM, CHAIN AND SPROCKET - A chain-sprocket mechanism is disclosed which is highly resistant to corrosion caused by a potential difference arising when metallic materials of different types contact each other. A chain of the chain-sprocket mechanism is structured by coupling a plurality of chain links that consist of pairs of outer plates, pairs of inner plates, bushings fixed to the inner plates and pins inserted through the outer plates, the inner plates and the bushing, which meshes with teeth of a sprocket. The surface of either of the bushing or the teeth is formed of a non-metallic material; thereby, a potential difference does not arise through the contact between the bushing and the teeth. Accordingly, corrosion caused by a potential difference can be avoided, i.e., the corrosion resistance of the chain-sprocket mechanism can be improved.||06-09-2011|
