To provide a magnetic field shielding structure which makes a leakage magnetic field from a power, line equal to or less than 1 m T on a railway vehicle floor and reduces a total weight, the power line being arranged under the floor and transmitting a heavy current.SOLUTION: A magnetic field shielding structure for a railway vehicle shields a magnetic field caused by a power line arranged under a floor of the railway vehicle and is characterized by it that the structure comprises a power line duct covering the power lines and a magnetic field shielding plate contacting with the power line duct and arranged between the floor and the power lines, and in a cross-section viewed from a direction orthogonal to the longitudinal direction of the power lines, both ends of the magnetic field shield plate incline in the opposite direction to the floor.SELECTED DRAWING: Figure 1

    【課題】鉄道車両の床面下には、大電流が流れる電力線が配置されている。この電力線からの漏れ磁界を床面において、1mT以下にし、全体の重量を軽くするような磁界遮蔽構造を提供する。【解決手段】鉄道車両の床下に配置される電力線からの磁界を遮蔽する磁界遮蔽構造であって、前記電力線を覆う電力線ダクトと、前記電力線ダクトに接し、前記床と前記電力線の間に配置される磁界遮蔽板を有し、前記磁界遮蔽板は前記電力線の長手方向に直角方向で断面視した時に両端が前記床と反対方向に傾斜していることを特徴とする鉄道車両の磁界遮蔽構造。【選択図】図1
