Abstract

The invention relates to a tensioner (1) for a traction drive with a rotationally fixed housing (2) to a side of which a rotatable swivel arm (10), provided with a rotatable tension roller, is associated. A torsion spring (7) is placed between the housing (2) and the swivel arm (10) for loading the swivel arm (10) in the direction of an end position. Support of the tension spring (7) is realized by an insert (17a) placed in a circular ring shaped space (16) radially defined by a housing portion and the torsion spring (7).
