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.
