Abstract
Punched and bent parts (1, 2, 3), manufactured by non-cutting shaping, are assembled to a rigid box by using exclusively mutual riveting, optionally in part also spot welding, of the material of the punched and bent parts, thus without any additional material requirements. The parts (13) serving for bearing the steering shaft (15) are high precision pieces also obtained by non-cutting shaping. A very efficient, high precision manufacturing is thus achieved free from any finishing treatment and without auxiliary means for the connection of the punched and bent parts.
