A coil alignment device includes: a plate-shaped first jig having a plurality of grooves arranged along a circumferential direction so as to extend toward a radial-direction outer side; and a second jig that can contact with a segment coil inserted in the first jig. Each groove includes a storage portion extending along a radial direction and having a first length so that leg portions of the segment coils can be stored side by side in the radial direction, and a guiding portion extending from the storage portion toward the radial-direction outer side, and has a first shape so that, using, as a fulcrum, one leg portion inserted in the storage portion, the other leg portion is movable toward the storage portion. The second jig is movable to press the segment coil from a radial-direction side and store the other leg portion into the storage portion.

A coil groupG is composed of windingsU toW for U phase, V phase, and W phase. One endsUtoWof the windings for the respective phases composing the coil groupG are connected to respective power supply bus barsU toW, and the other endsUandWof the windings for the phases positioned at both ends in the circumferential direction in the coil groupG extend toward the other endVof the winding for the rest of the phases, whereby the other endsUtoWof the windings for the respective phases are mutually connected.
