PROBLEM TO BE SOLVED: To suppress the displacement of in-vehicle equipment in relation to a ground segment, and to suppress the vibrations of an in-vehicle equipment mounting part while preventing an increase in weight, for a bogie on which in-vehicle equipment is mounted.SOLUTION: A bogie for a railroad vehicle consists of a linkage for suppressing the displacement of an in-vehicle equipment mounting part caused by the movement of a suspension. The linkage comprises: the in-vehicle equipment mounting part; a first link including a first pivot connected so as to be freely rotatable to either an axle box or a member integrated with the axle box which is displaced; a second pivot connected so as to be freely rotatable to either a bogie frame or member integrated with the bogie frame which is displaced; and a second link which includes a third pivot connected so as to be freely rotatable to the first link. The in-vehicle equipment mounting part is arranged on the bogie outer side rather than an axle center in the vehicle longitudinal direction, and the second pivot is arranged on the bogie center side rather than the axle center in the vehicle longitudinal direction.SELECTED DRAWING: Figure 1

    【課題】車載機器が取り付けられる台車において、地上設備に対する車載機器の変位を抑制するとともに、重量増加を防止しながら車載機器取付部の振動を抑制する。【解決手段】鉄道車両用台車は、サスペンションの動作による車載機器取付部の変位を抑制するリンク機構を備え、前記リンク機構は、前記車載機器取付部と、軸箱又は前記軸箱と一体に変位する部材に回動自在に連結される第1ピボット部とを含む第1リンクと、台車枠又は前記台車枠と一体に変位する部材に回動自在に連結される第2ピボット部と、前記第1リンクに回動自在に連結される第3ピボット部とを含む第2リンクと、を有し、前記車載機器取付部は、車両長手方向において車軸の中心よりも台車外側に配置され、第2ピボット部は、車両長手方向において前記車軸の中心よりも台車中央側に配置されている。【選択図】図1
