ABSTRACT:
A chain tensioning device includes a pair of levers interconnected and fixed at one end to a rotatably supported base and extending along the chain to be tensioned and a tensioner connected to the other end of one of the pair of levers. One of the levers is disposed on the end side of the chain to be tensioned as viewed from the rotatably supported base and has a convexly curved surface touching internally the chain, and a shoe attached to the convexly curved surface. The other of the levers is disposed on the departure side of the chain as viewed from the base and has a convexly curved surface touching externally the chain, and a shoe attached to the convexly curved surface. A projection on a side of the one of the levers opposite to the shoe for receiving a thrusting force from the tensioner 20 and applying such thrusting force to the interconnected levers.
