A starter device () for a combustion engine (), particularly of a motor vehicle. The device includes a rotary electrical machine () comprising a drive member () and a tensioner. A belt () collaborates with the drive member of the rotary electrical machine and with the combustion engine in order that the latter can be started using the belt rotationally driven by the electrical machine in a first direction (A). A tensioner () presses against a length () of the belt that runs between the electrical machine and the combustion engine. As the rotary electrical machine rotates in a second direction (B) the opposite of the first, it is possible for the tensioner to be brought from a stopped position into a position for beginning to start the combustion engine. The movement from the stopped position to the position for beginning to start being accompanied by a lengthening of said length of belt and/or by an increase in the tension in this length of belt.
