A guide member includes a first diametrically directed side guide section and a second diametrically directed side guide section formed by bending a single member at a bent portion. The first diametrically directed side guide section guides predetermined portions of electric conductors on a diametrically directed side of a slot. Further, the second diametrically directed side guide section guides predetermined portions of the electric conductors on a diametrically directed side of another slot adjacent to the slot. The bent portion is supported by a supporting body.
