<P>PROBLEM TO BE SOLVED: To fix a metallic tube to a rotor core while durability of the metallic tube is improved in a rotor for rotary electric machine including: the rotor core through which a rotor shaft passes and which is fixed to the rotor shaft; a plurality of magnets arranged in a plurality of places by leaving a space in a circumferential direction of an outer periphery of the rotor core; and the metallic tube which has a cylindrical portion engaging the magnets and is fixed to the rotor core. <P>SOLUTION: A metallic tube 40 integrally has a flange portion 40b which extends to an inner side in a radial direction from one end of a cylindrical portion 40a and makes a tip portion abut on one end face 38a in an axial direction of a rotor core 38. A curve part 40ba swelled outward in the axial direction from one end of the cylindrical portion 40a at a longitudinal face including the axial line of a rotor shaft 8 is arranged in the flange portion 40b. The curve part 40ba is formed to project outward in the axial direction rather than the one end face 38a in the axial direction of the rotor core 38. <P>COPYRIGHT: (C)2012,JPO&INPIT |
