Abstract: An annular conductor retaining device has a retention guide portion formed by blades arranged in a cylindrical shape with gaps therebetween. An annular conductor is inserted into two of the gaps across a plurality of the blades. The next annular conductor is inserted into the gaps to partially overlap the previously arranged annular conductor. This step is repeated so that the annular conductors are arranged in a spiral shape in the retention guide portion. The retention guide portion and the inner circumferential part of the core are fitted to each other, and the gaps and the slots of the core are made to coincide with each other. A pusher is inserted into the inner circumferential part of the retention guide portion so that the annular conductors are caught on the pusher, to move them in the axial direction into the slots of the core, and thus become the coils.

Abstract: An insertion groove is disposed on a tubular portion overlapping portion that is overlapped with an inner circumferential surface of a tubular portion of the stator core. Inter-coil insulating bodies that are disposed between a plurality of stator coils include a groove inserted portion. The groove inserted portion includes: a first inserted portion that can be inserted inside the insertion groove when the insulating film is in a bent and folded state; and a second inserted portion that is contiguous to the first inserted portion, a shape of a visible outline of a cross section of the second inserted portion being different than that of the first inserted portion. The second inserted portion generates a stronger elastic force of recovery than the first inserted portion when the groove inserted portion is inserted into the insertion groove.
