Abstract

A chain tensioning device is adapted to be coupled to a vehicle body and to be adjacent to a chain, and includes a connecting segment, a metallic resilient segment, a fixing member and a guiding member. The connecting segment includes a securing portion adapted to be coupled to the vehicle body and an extending portion adapted to be under the chain. The resilient segment is connected to the extending portion of the connecting segment via the fixing member, and has a spring constant which ranges from 0.01 to 1000 N/mm, and a Young's modulus which ranges from 69 to 220 megapascals. The guiding member is connected to the resilient segment and is biased by the resilient segment for maintaining a tension of the chain.
