To provide an eddy current type rail brake device in which the length in a longitudinal direction of a railway vehicle is shortened.SOLUTION: An eddy current type rail brake device 1 includes: a magnetic array 40; a support member 3; a magnetic electrode block 4; a plurality of pole pieces 5; and a slide device 6. The magnetic array 40 is arranged in one array in longitudinal direction. The magnetic electrode block 4 is adjacent to a permanent magnet 2 of one end of the magnetic array 40, and is a magnetic material. When viewing the slide device 6 from an upper direction of the eddy current type rail brake device 1, a plurality of permanent magnets is arranged so that one permanent magnet and one pole piece are overlapped in a brake state. In a non-brake state, two permanent magnets adjacent in the longitudinal direction are overlapped with one pole piece 5, and the magnetic electrode block 4 and the permanent magnet 2 adjacent to the magnetic electrode block 4 are overlapped with the pole piece 5 of one end in the longitudinal direction.SELECTED DRAWING: Figure 2

    【課題】鉄道車両の左右方向の長さを短くした渦電流式レールブレーキ装置を提供する。【解決手段】渦電流式レールブレーキ装置1は、磁石列40と、支持部材3と、磁極ブロック4と、複数のポールピース5と、スライド装置6と、を含む。磁石列40は、前後方向に一列に配置される。磁極ブロック4は、磁石列40の一方の端の永久磁石2と隣接し、磁性体である。渦電流式レールブレーキ装置1の上方から見て、スライド装置6は、制動状態のときに複数の永久磁石を1つの永久磁石と1つのポールピースとが重複するように配置し、非制動状態のときに前後方向において隣接する2つの永久磁石2を1つのポールピース5と重複させ、かつ、磁極ブロック4及び磁極ブロック4と隣接する永久磁石2を前後方向の一方の端のポールピース5と重複させる。【選択図】図2
