PROBLEM TO BE SOLVED: To provide a landing detection mechanism and a method of manufacturing the landing detection mechanism capable of detecting the landing of a spreader at high accuracy and stably.SOLUTION: A detection rod 10 formed with a rod-shaped body having the vertical direction z as an axial direction is disposed in a spreader 2 in a state capable of moving in the vertical direction z. A target member 11 is fixed to the detection rod 10, and a landing detection sensor 12 is disposed at the side of the detection rod 10. Further, a rotation prevention mechanism 17 is provided for preventing the target member 11 from being rotated around the central axis of the detection rod 10.SELECTED DRAWING: Figure 6
【課題】スプレッダの着床を高い精度で且つ安定的に検出できる着床検出機構および着床検出機構の製造方法を提供する。【解決手段】上下方向zを軸方向とする棒状体で構成した検出ロッド10を上下方向zに移動可能な状態でスプレッダ2に配置して、検出ロッド10にターゲット部材11を固定して、検出ロッド10の側方に着床検出用センサ12を配置して、ターゲット部材11が検出ロッド10の中心軸まわりに回転することを阻止するまわり止め機構17を設置する。【選択図】図6
