A rotor shaft is supported in a rotatable manner at both ends by bearings respectively disposed to a housing forming a part of a stator and provided with a positioning portion of the bearing in at least one shaft end. The positioning portion is formed of an annular step-like rise portion that abuts on a circular arc surface provided to an inner ring corner of the bearing. A rotor shaft capable of holding the bearing in a stable manner over a long period is thus obtained without increasing the number of components and the numbers of working processes and assembly man-hours for the shaft. It thus becomes possible to solve problems, such as an increase in cost due to a large amount of working margin and increases of the direct material cost and in weight due to a larger finishing diameter of the shaft.
