Abstract
A coil fastening part in a stator of the present invention can be turned about its axis of rotation in a gap between an end face of a tooth and an inner circumferential surface of a unit coil and has a noncircular shape cross-section vertical to its axis of rotation. The noncircular shape cross-section of the coil fastening part has a first dimension which is represented by a first line segment which intersects its axis of rotation and a second dimension which is represented by a second line segment which intersects its axis of rotation, is different from the first line segment, and is larger than the first dimension. The coil fastening part is arranged in the gap in a state where the second line segment is aligned with the height direction of the gap and pushes against both the end face and the inner circumferential surface to thereby fasten the unit coil to a tooth.
