A traction mechanism drive (1), such as a control drive of an internal combustion engine, having an endless traction mechanism, such as a link chain, connecting a drive gear (2) and at least one driven gear (3) in a form-fitting manner, at least one clamping device (5) actuated by a pressure medium and a guiding rail (6) being arranged on the periphery of the traction mechanism. At least the guiding rail (6) includes a carrier body (7) and a resiliently flexible sliding body (8) connected to the carrier body (7) on the traction mechanism side. A spring element (18) is arranged in a free space (16) between the upper side (14) of the carrier body (7) and a lower side (15) of the sliding body (8). In order to improve the damping of the traction mechanism, the spring element (18) includes at least one flexible spring (19) connected integrally to the carrier body (7) and the sliding body (8).
