The force of a drive shaft (1) is transmitted to a first drive element (4,5), engaged with a second drive element (6). The first drive element is mounted to pivot, and by means of a pivot lever can swivel without coming out of engagement with the second drive element. The transmission produces by its passing long side additional torsion of the first element, and with it the second element, in the same direction as the pivoting operation itself.
