GAP MEMBER, MAGNETIC CORE AND REACTOR

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. 【課題】接着剤を使用することなく、コア片同士を連結できるギャップ部材を提供する。【解決手段】コア片３１ｍとコア片３１ｍとの間に介在されるギャップ部材４であって、両側に前記両コア片３１ｍが配置され、互いに対向する端面間に介在されるギャップ板部４ｇと、ギャップ板部４ｇの周面から両コア片３１ｍの端面よりも外方に突出する突出部４ｅと、突出部４ｅの両側からギャップ板部４ｇの厚み方向に延出し、各コア片３１ｍの端部の周面を囲む壁部４ｆと、壁部４ｆの内周面から内方に突出して、各コア片３１ｍの周面を押圧する突起部４ｐと、を有する。【選択図】図３
