PROBLEM TO BE SOLVED: To provide a work grip changing device which minimizes effects of deflection due to gravity of a work and reduces the installation area.SOLUTION: A grip changing device M for a work W executes clamping with a robot gripper and includes a swing frame 20 freely swingable in the horizontal plane and a pair of gripping bodies 31 and 32 which are arranged oppositely on one and the other sides, in the horizontal direction, of the swing frame 20, are capable of freely approach and separate from each other and approach each other to hold plate-like work W in the horizontal direction and driving mechanisms 41 and 42 for the gripping bodies 31 and 32. One gripping body 31 is positioned and held at a reference position through strong thrust by the drive mechanism 41, and, in this condition, the other gripping body 32 approach with weaker thrust and holds the work W. 【課題】ワークの重力による撓みの影響を極力無くすと共に設置面積を小さくすることができるワークの掴み換え装置を提供する。【解決手段】ロボットグリッパによりクランプしているワークＷの掴み換え装置Ｍであって、水平面内で旋回自在な旋回フレーム２０と、旋回フレーム２０の水平方向における一端側と他端側に対向配置されて水平方向に互いに接近離間自在とされ、接近することで板状のワークＷを水平方向から挟持する一対の把持体３１，３２及びそれらの駆動機構４１，４２とを具備し、一方の把持体３１は基準位置に駆動機構４１により強い推力で位置決め保持され、この状態で他方の把持体３２がそれより弱い推力で接近し、ワークＷを挟持する。【選択図】図１
