PROBLEM TO BE SOLVED: To restrain the rotational oscillation of an electric instrument for railway vehicle in a pitch or rolling direction excited by oscillation of a vehicle body, and to prevent noise generation resulting from accelerated degradation of an elastic body and oscillation in the electric instrument suspended to the railway vehicle or a box body installed to the railway vehicle for internally equipping the instrument.SOLUTION: An electric instrument 12 installing a support member 13 angled at an optional angle θ, and a support member 14 installed to a box body 2 are installed inside the box body via an elastic support body 16. Alternatively, the rotation center 102 of a rotational oscillation 103 in a pitch direction is provided at a lower side of the ceiling plane 12a of the electric instrument 12.SELECTED DRAWING: Figure 3
【課題】鉄道車両もしくは鉄道車両に取り付けられた電気機器を内装するための箱体に対して,弾性体を介して懸架される鉄道車両用電気機器において,車体の振動により励起される上記電気機器のピッチ方向もしくはロール方向への回転振動を抑制し,弾性体の劣化促進および振動による騒音発生を抑制すること。【解決手段】任意の角度θに曲げた支持部材13を取り付けた電気機器12と箱体2に取り付けられた支持部材14とを弾性支持体16を介して取り付ける。またはピッチ方向の回転振動103の回転中心102を電気機器12の天井面12aより下側に設ける。【選択図】 図3
