PROBLEM TO BE SOLVED: To provide a hanging clamp including a fastened/opened state switching device which allows an amount of projecting outward from a clamp body to be small, and which can be easily operated.SOLUTION: A switching device for performing switching operation between a fastening possible state in which initial fastening force generated by tension of a pull spring and fastening force according to a hanging load are given and a lock opened state in which a cam is not projected out from a workpiece insertion port includes: a cylindrical housing 31; a lock pin 32; a push spring; a lock regulation plate 34 fixed to the cylindrical housing; and a rotatable lock lever 35. When the lock lever is aligned with the lock regulation plate and a lock lever pin 36 is entered into a locking hole 37, the lock pin stops at a retreat position against energizing force of the push spring, and movement of a link mechanism is not impeded. Therefore, the fastening possible state is maintained. When it is not the case, the lock pin is projected into the lamp body to impede the movement of the link mechanism and the lock opened state is maintained.SELECTED DRAWING: Figure 6

    【課題】クランプ本体から外方への突出量が小さく且つ操作容易な締付/開放状態切替装置を備えた吊りクランプを提供する。【解決手段】引きバネの張力による初期締付力および吊り荷重に応じた締付力を与える締付可能状態と、カムをワーク挿入口に突出させない開放ロック状態との間で切替操作するための切替装置が、円筒ハウジング31と、ロックピン32と、押しバネと、円筒ハウジングに固定のロック規制板34と、回転可能なロックレバー35とを有する。ロックレバーがロック規制板と整列してロックレバーピン36が係止穴37に入り込んでいるとき、ロックピンは押しバネの付勢力に抗して後退位置に止まり、リンク機構の動きを阻害しないので、締付可能状態を維持する。そうでないときは、ロックピンがクランプ本体の内部に突出してリンク機構の動きを阻止し、開放ロック状態を維持する。【選択図】図6
