To provide a safety device for an aerial work platform vehicle capable of further improving the safety.SOLUTION: A safety device includes a guard pipe 70 provided on an upper part of a work bench 40 and arranged around an operator boarding on the work bench 40, an elastic member 81 provided between the upper part of the work bench 40 and the guard pipe 70 to elastically support the guard pipe 70 with respect to the work bench 40 to be movable in a longitudinal direction, a lateral direction, and a vertical direction, a wire 101 connected to the guard pipe 70 and moving in a length direction of itself in conjunction with the movement of the guard pipe 70 with respect to the work bench 40, and a safety switch mechanism 100 detecting the movement of the wire 101 in the length direction. When the movement of the wire 101 in the length direction is detected by the safety switch mechanism 100, the operation of a boom is restricted.SELECTED DRAWING: Figure 5

    【課題】更なる安全性の向上を図るこことのできる高所作業車の安全装置を提供する。【解決手段】安全装置は、作業台40の上部に設けられて当該作業台40に搭乗した作業者の周囲に配されるガードパイプ70と、作業台40の上部とガードパイプ70との間に設けられて、作業台40に対してガードパイプ70を前後方向、左右方向および上下方向に移動可能に弾性的に支持する弾性部材81と、ガードパイプ70に接続されて作業台40に対するガードパイプ70の移動に連動して自身の長さ方向に移動するワイヤ101と、ワイヤ101の長さ方向の移動を検出する安全スイッチ機構100とを備え、安全スイッチ機構100においてワイヤ101の長さ方向の移動が検出されたときに、ブームの作動を規制するように構成されている。【選択図】図5
