A belt tensioner with a retainer can be brought into contact with a belt via a belt support for applying a tensile force. The retainer is joined at a distance from the belt support to a radial plain bearing and it can be swivelled about the axis of rotation of the radial plain bearing, whereby the tensioning and swivel movements of the belt support occur under the action of a coil spring. For a belt tensioner of this type, which with a compact construction runs essentially wear-free, it is suggested that the retainer is subject to the action of a spring, which exerts a force (F) essentially parallel to the axis of rotation on the retainer, the said force (F) counteracting the force (F) exerted by the belt on the retainer.
