PROBLEM TO BE SOLVED: To provide a push button device for an elevator which can be pushed continuously even when a display board is pushed with strong force and is deformed or is broken.SOLUTION: A push button device is applied to a control panel installed in a car of an elevator, and, as a structure of lighting a pushed display board 2, includes: an annular frame-shaped protective cover frame 1 with a disc-like display board 2 attached and fixed to an inner side of a front surface side; a switch 3 which is arranged on a back side of the frame 1, is pushed in and is turned on by an end surface of the frame 1 when the display board 2 is pushed; and a light emitting device 4 having a light emitting part which is energized and emits light in the on-state of the switch 3 so as to be surrounded by the switch 3 in a position on a substrate opposite to the display board 2. The frame 1 is formed of a hard material having higher mechanical strength than the display board 2, and even after the display board 2 with low mechanical strength is pushed with strong force, and is deformed or is broken, pushing operation of turning the switch 3 on can be conducted.SELECTED DRAWING: Figure 1

    【課題】表示板が強い力で押下操作されて変形したり、或いは破壊されても継続して押下操作が可能なエレベータ用押し釦装置を提供する。【解決手段】この押し釦装置は、エレベータの乗りかご内に設置される操作盤に適用されると共に、押下操作された表示板2を点灯する構造として、円板状の表示板2を表面側の内側に装着固定した円環枠状の保護カバー枠1と、この枠1の奥側に配置されて表示板2が押下操作されたときに枠1の端面によって押し込まれてオン状態となるスイッチ3と、表示板2に対向する基板上の位置でスイッチ3に囲まれるようにスイッチ3のオン状態で通電して発光する発光部が配備された発光装置4と、を備え、枠1が表示板2よりも機械的強度の高い硬質材料で成形されており、機械的強度の低い表示板2が強い力で押下操作されて変形したり、或いは破壊された後にも継続してスイッチ3をオン状態にする押下操作が可能となっている。【選択図】図1
