Skew correction device for stator core and skew correction method

A skew correction device for stator cores that corrects a lamination shift in a circumferential direction of a substantially annular stator core formed by laminating a plurality of thin sheets having a plurality of projecting parts projecting outwards at an outer circumference thereof so that the projecting parts align in a laminating direction, the device comprising:

• a support member capable of supporting from outwards a protrusion of the stator core formed by the plurality of projecting parts aligning;
• a means for pressing the support member towards an inner side in a radial direction of the stator core;
• and
• a means for correcting lamination shift in the circumferential direction, by causing the support member to rotate in a direction in which the lamination shift in the circumferential direction is corrected with the radial direction as an axis of rotation, in a state supporting the protrusion from outwards by pressing the support member by way of the first pressurizing means.
