Chain tensioning device

A chain tensioning device adapted to be coupled to a vehicle body and to be adjacent to a section of a chain that extends in a front-rear direction, said chain tensioning device comprising:

• a connecting segment including
• a securing portion that has a first end adapted to be coupled to the vehicle body, and
• an extending portion that extends from a second end of said securing portion, and that is adapted to be spaced apart from the section of the chain;
• a metallic resilient segment including a connecting portion that is connected to said extending portion of said connecting segment, adapted to be spaced apart from the section of the chain in a top-bottom direction transverse to the front-rear direction, and having a spring constant which ranges from 0.01 to 1000 N/mm, and a Young's modulus which ranges from 69 to 220 megapascals, a thickness of said resilient segment in the top-bottom direction being smaller than a width of said resilient segment in a left-right direction, which is transverse to the front-rear direction and the top-bottom direction, and a length of said resilient segment in the front-rear direction;
• a fixing member connecting said connecting portion of said resilient segment to said extending portion of said connecting segment;
• and
• a guiding member connected to an end of said resilient segment that is distal from said connecting portion of said resilient segment, adapted to be disposed between said resilient segment and the section of the chain, and biased by said resilient segment for maintaining a tension of the chain.
