Embodiment Construction
[0043] Figure 1 to Figure 13 An example of embodiment of the present invention is shown. Including this example, the present invention is characterized in that it is used to support the steering column 6a on the vehicle body 11 together with the housing 9a for supporting the components of the electric power steering device (see Figure 14 ) structure of the support bracket 14a and its manufacturing method. The basic configuration of other electric power steering devices is the same as that of conventional devices.
[0044] The support bracket 14a is integrally formed into a left-right asymmetrical shape by performing punching and bending by punching a metal plate that can ensure sufficient strength and rigidity, such as a steel plate or a stainless steel plate. The thickness of the metal plate is appropriately selected by comprehensively judging the strength, rigidity, and workability of the material used, and is, for example, about 2.0 mm to 4.0 mm when using a stainless st...
