Claims

[Claims for Utility Model Registration] 1. In a roller chain in which an elastic body is provided at both ends of the roller between the roller link plates, when the sprocket bites the elastic body into the chain, the breaking strength of the chain is approximately A chain structure that has a gap and elastic force that has a clamping strength of 8% or more, and is made of a wrap-like elastic body that is filled with oil. 2. The chain structure according to claim 1, wherein the elastic body is a disc spring having a plate thickness of about 8% or more of the chain pitch. 3. The chain structure according to claim 1, wherein when the elastic body is a flat disc spring, a gap is provided at the contact portion with the roller link plate and the roller.
