<p>PROBLEM TO BE SOLVED: To provide a gap member which allows connection between core pieces without using an adhesive.SOLUTION: A gap member 4 is interposed between a core piece 31m and another core piece 31m. The gap member 4 comprises: a gap plate 4g which has both of the core pieces 31m arranged on both sides, and which is interposed between end surfaces facing each other; a protrusion 4e which protrudes, from the peripheral surface of the gap plate 4g, further outward than the end surfaces of both of the core pieces 31m; a wall 4f which extends from both sides of the protrusion 4e in the thickness direction of the gap plate 4g so as to surround the peripheral surface of the end of each core piece 31m; and a protrusion 4p which protrudes inward from the inner peripheral surface of the wall 4f so as to press the peripheral surface of each core piece 31m.</p> |
