Abstract

A tensioner for a belt, a chain or the like, which has a tensioning lever that is in operative connection with a helical spring, is pivotable about a fixed axis and on the tensioning lever a receptacle for a tensioning element that bears against the belt, chain or the like is arranged. The helical spring is held at its ends by spring receptacles with the helical spring being screwed to at least one of the spring receptacles. This construction ensures a reliable and easy-to-assemble connection between the helical spring and the spring receptacle is achieved.
