Abstract:
1. A tensioning device for an endless drive device comprising a tensioning rail and a housing with a spring loadable tensioning piston guided in a sliding manner in a receiving bore of the housing, an adjustment device to adjust a working range of the tensioning piston, a transport locking device, wherein the adjustment device comprises a retainer element arranged on the housing having a first spring arm and a retainer profile arranged in the forward section of the tensioning piston in a tensioning direction, wherein the transport locking device comprises a transport groove in the tensioning piston, the first spring arm of the retainer element can be engaged with the transport groove, and an unlocking element, wherein the unlocking element is part of the tensioning rail and has a first ramp section that can be brought into functional contact with the first spring arm, where said first ramp section exerts an unlocking force over a predefined travel path of the unlocking element on said first spring arm relative to the tensioning piston, forcing said first spring arm out of the transport groove.
