To provide a ground coil for a floating type railroad which can reduce stress in a fastening part.SOLUTION: A ground coil for floating type rail road comprises a floating guide conductor, a propulsion conductor, and a mold part. The floating guide conductor electromagnetically acts with a superconducting magnet provided in a vehicle. The propulsion conductor electromagnetically acts with the superconducting magnet provided in the vehicle. The mold part is configured from an insulation material, and molds the floating guide conductor and the propulsion conductor. The mold part comprises a fastening hole, and a first recess. A fastening member, which is fixed to a support member arranged on a guideway, is inserted in the fastening hole. The first recess has a first seating face, a bottom, and a peripheral wall. The first seating face is formed around the fastening hole. The bottom is arranged around the first seating face. The peripheral wall has a continuous part which inclines or curves toward a surface on one side in fastening axial direction from the bottom, and continuously extends.SELECTED DRAWING: Figure 3

    【課題】 締結部における応力を低減できる、浮上式鉄道用地上コイルを提供する。【解決手段】 一実施形態にかかる浮上式鉄道用地上コイルは、浮上案内用導体と、推進用導体と、モールド部と、を備える。浮上案内用導体は車両に設けられた超電導磁石と電磁的に作用する。推進用導体は前記車両に設けられた前記超電導磁石と電磁的に作用する。モールド部は、絶縁材料で構成され、前記浮上案内用導体と前記推進用導体とをモールドする。モールド部は、締結孔、並びに、第1凹部、を備える。締結孔は、走行路に配される支持部材に固定される締結部材が挿入される。第1凹部は、第1座面、底部、及び周壁を有する。第1座面は、前記締結孔の周りに形成される。底部は前記第1座面の周りに配される。周壁は、前記底部から締結軸方向の一方側の表面に向けて傾斜または湾曲して連続して延びる連続部を有する。【選択図】 図3
