GRIPPER

PROBLEM TO BE SOLVED: To achieve, with a simple structure, an operation for opening/closing a gripping arm.SOLUTION: A gripper 51 is characterized in that it includes: a pair of clamping members 71 and 72 which are rotatably connected with each other between a clamping position for clamping an object with a rotary axis AR51 as a center and a clamping release position for releasing the clamping of the object; a spring member 73 which energizes the clamping members 71 and 72 so that the clamping members 71 and 72 are in a clamping position; a handle 60 which is attached to the clamping member 72 so as to be arranged on the opposite side from the side where the object is clamped by the clamping members 71 and 72 across the rotary axis AR51 and which is gripped by the user; and a delivery member 74 which is arranged between the clamping members 71 and 72 and which rotates between a delivery position stretched between the clamping members 71 and 72 so as to be the clamping release position, with the rotary axis AR52 provided in the clamping member 71 as a center and a delivery release position for releasing delivery within the clamping members 71 and 72 so as to be the clamping position.SELECTED DRAWING: Figure 3 【課題】掴みアームを開閉するための操作を簡単な構造で実現する【解決手段】回転軸ＡＲ５１を中心にして、物体を挟持する挟持位置と、物体の挟持を解除する挟持解除位置との間で回転可能に互いが連結された一対の挟持部材７１，７２と、挟持部材７１，７２が挟持位置となるように挟持部材７１，７２を付勢するバネ部材７３と、回転軸ＡＲ５１を挟んで、挟持部材７１，７２により物体が挟持される側とは反対側に配置されるようにして挟持部材７２に取り付けられ、使用者により把持される柄６０と、挟持部材７１，７２間に配置され、挟持部材７１に設けられた回転軸ＡＲ５２を中心にして、挟持解除位置となるように挟持部材７１，７２間に掛け渡される掛渡位置と、挟持位置となるように挟持部材７１，７２間の掛け渡しが解除される掛渡解除位置との間で回転する掛渡部材７４とを備えることを特徴とする掴み器５１。【選択図】図３
