PROBLEM TO BE SOLVED: To prevent an inserted winding from getting snagged on an edge of a bridge piece or an edge of an insulating portion. SOLUTION: A plurality of first auxiliary pieces 40 for coupling are integrally formed on a first opposite end 321 of a first insulating portion 32 so that the first auxiliary pieces are extended toward a second insulating portion 34. A plurality of second auxiliary pieces 41 for coupling are integrally formed on a second opposite end 341 of the second insulating portion 34 so that the second auxiliary pieces are extended toward the first insulating portion 32. One end 361 of a bridge piece 36 is joined with and thermally welded to the outer surfaces of the first auxiliary pieces 40 for coupling. The other end 362 of the bridge piece 36 is joined with and thermally welded to the inner surfaces of the second auxiliary pieces 41 for coupling. COPYRIGHT: (C)2009,JPO&INPIT
