摘要：It is an object of the present invention to provide a rotor shaft capable of
sufficiently securing a fastening strength between an inner shaft and an outer shaft,obtaining an excellent anti-rotation torque, and reducing a weight of the rotor shaft. A
rotor shaft 3 is divided into an inner shaft 4 and an outer shaft 5. The inner shaft 4 includes a tip end portion 41, a rear end portion 43, and a thick portion 42. The thick portion 42 connects the tip end portion 41 and the rear end portion 43 with each other in the radial direction, and has the same inner diameter as that of the tip end portion 41 and the same outer diameter as that of the rear end portion 43. The outer shaft 5 includes an inner cylindrical portion 51, a magnetic body-mounting outer cylindrical portion 53, and a flange 52 that connects the inner cylindrical portion 51 and the magnetic body-mounting outer cylindrical portion 53 with each other. Outer peripheral surfaces 422 and 432 of the thick portion 42 and the rear end portion 43 and an inner peripheral surface 501 of the inserting hole 50 of the inner cylindrical portion 51 are brought into contact with each other, and the inner shaft 4 and the outer shaft 5 are fastened and fixed to each other. The flange 52 is disposed at a position opposed to the thick portion 42 in the radial direction.
