| description | To provide a noise countermeasure member which is improved in heat resistance or vibration resistance by suppressing radiation of electromagnetic wave noise generated by an electromotive force generated from magnetic leakage flux while adopting a metallic elastic pressing member for a member that elastically pressing a core component.SOLUTION: Between at least one core component of a pair of core components abutted to each other to form an annular magnetic substance core and a support member in which the core component is accommodated or supported, a metallic leaf spring improved in heat resistance or vibration resistance is disposed, and the core component is pressed by an elastic force of the leaf spring, such that the annular magnetic substance core is held in a formation state. In the leaf spring, multiple openings are provided along an axis of the magnetic substance core, thereby suppressing radiation generated by an electromotive force generated from magnetic leakage flux of the magnetic substance core.SELECTED DRAWING: Figure 3
【課題】コア部品を弾性押圧する部材に金属製の弾性押圧部材を採用しながら、漏洩磁束から生じる起電力で生じる電磁波ノイズの放射を抑止可能で、耐熱性や耐振性に優れたノイズ対策部材を提供すること。【解決手段】互いに当接させることによって環状の磁性体コアを形成可能な一対のコア部品の内、少なくとも一方のコア部品とコア部品を収納あるいは支持する支持部材との間に、耐熱性や耐振性に優れた金属製の板バネを配置し、板バネの弾性力によりコア部品を押圧して環状の磁性体コアを形成状態に保持するように構成し、板バネには、磁性体コアの軸に沿って複数の開口部を設けて、磁性体コア漏洩磁束から生じる起電力で生じる放射を抑止できるようにした。【選択図】図３ |
