Abstract
A supporting structure for a drive shaft of an electrically driven power steering motor is presented to prevent axial displacement of the drive shaft. Around the entire peripheral outer circumference of a hollow cylindrical drive shaft, a radially protruding flange section of a U-shaped cross section is provided to engage with the shaft bearing freely rotatably supporting the drive shaft, and prevent an axial displacement of the drive shaft. The support structure exhibits little deformation due to spring back, because of the improved resistance to axial loading and retains excellent original shape of the flange section.
