Intermediate portion of a projection (6) and a groove (7) have respectively formed therein: straight portions (6a, 7a) extending in a certain width in a direction normal to each end surface of yoke portions (2); and, near the straight portions closer to end surfaces of yoke portions, contracted portions (6c, 7c) having a width smaller than the width of the straight portions. When the projection (6) is fit by press fitting into the groove (7) in the normal direction, groove walls (2a, 2b) on both diametrically outer and inner sides of the groove (7) are deflected within an elastic region. When fit by pressing, the straight and contracted portions (6a, 6c) of the projection (6) are elastically tightened together at the straight and contracted portions (7a, 7c) of the groove (7), respectively. An apparatus for assembling a stator core has a plurality of radially disposed and radially movable jigs (13) for holding the segmented cores (1). Vertically movable cams (15) are provided vertically downwards on an upper vertically movable plate (11). By lowering the movable plate (11), the jigs are pushed radially inwards. By this pushing the plurality of segmented cores circumferentially approach each other. The projection (6) of each segmented core (1) is fit by press fitting into the groove (7) of the adjoining segmented core (1) in the circumferential direction, thereby connecting the segmented cores together. |
