The pressing member which is formed at its peripheral edge portion with a plurality of grooves includes a first pressing surface and a second pressing surface. A portion of the pressing member constituting the first pressing surface extends into a region located on an extension in a coil pressing direction of the grooves located radially of such portion, and the first pressing surface corresponds to the coil end portion of one coil. The second surface portion supports, in spaced-apart relation to the first pressing surface in the coil pressing relation, the coil end portion of another coil arranged such that a portion thereof overlaps a portion of the coil end portion corresponding to the first pressing surface.
