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.

The invention relates to a device for assembling, by screwing, a drive member, such as a drive pulley, with a shaft intended to be coupled to the rotor of a rotating electrical machine, the device including an additional, welded connection. According to the invention, this method of producing the assembly device is characterized in that the drive member screwed onto its shaft in the vertical position is welded from below. The invention can be used for rotating electrical machines, such as an alternator or a starter-alternator of a motor vehicle.
