COUNTERWEIGHT STATE DETECTION DEVICE
PROBLEM TO BE SOLVED: To provide a counterweight state detection device capable of preventing a feed amount detector from being damaged even if a user forgets to detach a hook serving as a hooking part from a left side flange serving as an engaging part.SOLUTION: A separation mechanism 5 is provided between a hook 1 and a wire 2 serving as a linear member. When a tensile force equal to or more than a predetermined tension value is applied to the wire 2, a portion coupled with a predetermined coupling force in the separation mechanism 5 (i.e. a portion where an upper magnet 5a and a lower magnet 5b are in contact with each other) is separated.SELECTED DRAWING: Figure 5
【課題】掛合部としてのフックを掛止部としての左側フランジから取り外すのを忘れても、繰出し量検出器の破損を防止可能なカウンタウエイト状態検出装置を提供することである。【解決手段】フック１と線状部材としてのワイヤ２との間に分離機構５が設けられており、ワイヤ２に所定の張力値以上の引張力が加わった場合には、分離機構５内の所定の結合力で結合した箇所（上部磁石５ａと下部磁石５ｂとが接した箇所）で分離するように構成されている。【選択図】図５
