<P>PROBLEM TO BE SOLVED: To provide a rotor for rotary electric machine, having end plates and a rotor core that has laminated electromagnetic steel sheets, that provides, without cutting, a structure for suppressing axial opening of the rotor core and that allows shock load and stress to be concentrated on different positions. <P>SOLUTION: End plates 10 allow respective elastic contact portions 18 formed by bending to press a rotor core 8 axially so as to suppress axial opening of the rotor core 8. Thus, a structure for suppressing the axial opening of the rotor core 8 is provided without cutting. Since stress concentration due to core pressure is absorbed and relieved by respective middle bent portions 18b, base-side pieces 17 on a counter-stator side of the respective elastic contact portions 18 are less likely to be affected by the stress concentration due to core pressure. More specifically, the stress concentration due to core pressure does not occur in counter-stator-side portions on which load due to a shock or vibration given to a rotor 3 is likely to be concentrated. <P>COPYRIGHT: (C)2013,JPO&INPIT |
