摘要： A rotor structure (1) is to be provided which can diminish stress concentration in teeth-wedge fitting portions located near magnetic poles of a rotor in a rotary electric machine. Teeth 6 have slant faces for abutment against slant faces of wedges 8 to retain the wedges in a fitted state between adjacent teeth, the wedges 8 having slant faces each formed at a predetermined angle relative to the radial direction of a rotor 1, and a circular arc is formed at each slant face rising position in the teeth 6. In this case, the radius of the circular arc formed at each slant face rising position 12 in a preset number of teeth 6 located near magnetic pole portions 7 of the rotor 1 is set larger that of the circular arc formed in the remaining teeth.
