Abstract
A belt or chain tension producing apparatus comprises a tension head engageable with a chain, belt or the like of a chain or belt drive and a tension piston on which the tension head is carried. The tension piston is guided longitudinally slidable in a guide body which is simultaneously a mounting element and is acted on by at least one tension spring engaged with it which is supported at its other end on the base of the guide body. In order to provide a particularly compact structure and thus also a more universal structure, at least a part of one side of the tension piston projects laterally from the guide body and the tension head is mounted laterally on a mounting surface on that projecting part. A recess may be provided in the tension head to better mount it on the tension piston.
