Abstract: To provide a stator producing device which can expand the distance between lead portions while suppressing interference between an extension blade and the lead portions.SOLUTION: A stator producing device uses an extension blade to expand the gap between lead portions of a segment coil formed of a rectangular conductor which is inserted in a slot portion of a stator core. The lead portions are projected from an end surface of the stator core. The lead portion includes a first side surface and second and third surfaces that are chamfered and adjacent to the first side surface. The extension blade includes an inclined portion having a first inclined surface that comes into sliding contact with the first side surface, and a pair of projections that are disposed on both sides of the inclined portion and are projected toward the lead portions. The pair of projections include a second inclined surface and a third inclined surface that come into sliding contact with the second side surface and the third side surface respectively. When the lead portion radially slides along the second inclined surface and the third inclined surface, the gap between the lead portions is ensured. When the lead portion radially slides along the first inclined surface, the inclined portion expands the distance between the lead portions.SELECTED DRAWING: Figure 3
