Abstract

Provided is a twisting jig for a stator, capable of suppress radial deformation of projected portions of segment coils projected from a stator core at the time of a twisting process. The twisting jig 9A for a stator 1 in which projected portions 7A are bent in a circumferential direction by a twisting process, the projected portions including coil ends 7a of segment coils 7 held by a stator core, is provided with a twisting member 13 having a holding portion 17 that holds the coil ends 7a to displace the coil ends relative to the stator core 3 in an axial direction and the circumferential direction and bend the projected portions 7A, and a restraining wall 31 supported so as to be movable in the axial direction on an outside in a radial direction with respect to the twisting member 13, to restrain the projected portions 7A on the outside in the radial direction at the time of the bending in a projecting state of the restraining wall projecting with respect to the holding portion 17 in the axial direction.
