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 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. A detected part 16 is formed at a position facing the landing detection sensor 12 when the target member 11 becomes a same height as the landing detection sensor 12, and the detected part 16 is formed in an arc shape setting the central axis of the detection rod 10 as the center.SELECTED DRAWING: Figure 8

    【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が着床検出用センサ12と同じ高さになったときに着床検出用センサ12と対向する位置に被検出部16を形成して、この被検出部16を検出ロッド10の中心軸を中心とする円弧形状に形成する。【選択図】図8
