Abstract

The invention relates to a flexible drive (1) placed in a closed installation space (6) of an internal combustion engine (2). An associated tensioning device (10) comprises a tensioning rail (9) that can be pivoted about a rotation axis (11) by a means of force (12), the flexible means (3) being guided over two guide rolls (13a, 13b) of the tensioning rail (9).
