PROBLEM TO BE SOLVED: To provide a railway vehicular electric component fixing mechanism capable of effectively preventing an electrical contact failure or destruction of a railway vehicular electric component caused by vibrations.SOLUTION: This railway vehicular electric component fixing mechanism that fixes a railway vehicular electric component unit 22 inserted from a backside to be housed in a box body arranged in a railway vehicle to the box body is provided with, on the backside of the unit: a guide pin 34 which is arranged in parallel to the insertion direction of the unit with respect to the box body; and a guide pin receiver 35 which holds the tip of the unit housed in the box body and which is provided in the box body. The unit has a front side which is opposed to the backside fixed to the box body. The guide pin has a first male or female conical surface at a tip 34B. The guide pin receiver has a second make or female conical surface 35A similar in shape to the conical surface at the tip of the guide pin. The tip of the guide pin is held by bringing the second conical surface into contact with the first conical surface of the guide pin housed in the box body.SELECTED DRAWING: Figure 2
【課題】振動に起因する鉄道車両用電気品の、電気的な接触不良や破損を、有効に防止し得る鉄道車両用電気品の固定機構を提供する。【解決手段】鉄道車両に配設された箱体内に、背面側から挿入するようにして収納される鉄道車両用電気品のユニット22を、箱体に固定する鉄道車両用電気品の固定機構において、ユニットの背面側に、箱体に対するユニットの挿入方向と平行に配置されたガイドピン34と、箱体内に設けられ、箱体に収納されたユニットのガイドピンの先端を保持するガイドピン受け35とを設け、ユニットは、背面と対向する前面側が箱体に固定され、ガイドピンは、先端34Bに雄型又は雌型の第1の錐面を有し、ガイドピン受けは、ガイドピンの先端の錐面と同形状の雌型又は雄型の第2の錐面35Aを有し、第2の錐面と、箱体内に収納されたガイドピンの第1の錐面とを当接させるようにしてガイドピンの先端を保持するようにした。【選択図】図2
