PROBLEM TO BE SOLVED: To swiftly and securely achieve the stretching of a transmission chain. SOLUTION: Disclosed is a device for stretching a transmission chain comprising pairs of elongated rocker elements 20 mutually coupled by links 22, and rocker elements 20 being destined a torque transferring cooperation with the pulley sheaves of a pulley sheave transmission and comprising a first and a second supporting surface 16, 46 supporting a chain 18 and having an adjustable mutual distance to generate tensile stresses in the chain 18 supported thereby, in which the first supporting surface 16 is freely rotatable accommodated between the first ends of two distant frame parts 4, 6, the second supporting surface 46 is freely rotatable accommodated on an auxiliary carrier 30 between the two frame parts 4, 6, the carrier 30 being provided with two opposite stubby shafts 26b, protruding therefrom and of which the shaft 26b lies at a distance from the axis of rotation of the second supporting surface 46 which is rotatably supported by the auxiliary carrier 30 and lies near the second end of the frame parts 4, 6 while of the supporting surfaces 16. 46 at least one can be driven in rotation.
