Summary:To provide a holding device which can hold a workpiece with pads having fluidity even if there is not enough space available at both sides of the workpiece.SOLUTION: A holding device 5 holds a workpiece and includes: a left arm unit 5L and a right arm unit 5R; a gripper body 6 which opens or closes these arm units 5L, 5R along a holding direction; pads 59, 59 having fluidity and provided at the arm units 5L, 5R; a vacuum pump which changes hardness of the pads 59, 59; and a roller unit 8 which causes the rollers 82, 82 to roll along surfaces of the pads 59, 59 to level the surfaces of the pads 59, 59. The roller unit 8 causes the rollers 82, 82 to roll along the surfaces of the pads 59, 59 so that surfaces of the rollers 82, 82 sequentially contact with the surfaces of the pads 59, 59 along a vertical direction from the lower end side to the upper end side.SELECTED DRAWING: Figure 9 【課題】ワークの両側に十分なスペースが無い場合であっても、流動性を有するパッドによってワークを把持することができる把持装置を提供すること。【解決手段】把持装置5は、ワークを把持するものであって、左アームユニット5L及び右アームユニット5Rと、これらアームユニット5L,5Rと、アームユニット5L,5Rを把持方向に沿って開閉するグリッパ本体6と、流動性を有しかつアームユニット5L,5Rに設けられたパッド59,59と、パッド59,59の硬さを変化させる真空ポンプと、ローラ82,82をパッド59,59の表面に沿って転がすことによってパッド59,59の表面を均すローラユニット8と、を備える。ローラユニット8は、ローラ82,82の表面がパッド59,59の表面のうち鉛直方向に沿って下端側から上端側へ向かって順に当接するように、ローラ82,82をパッド59,59の表面に沿って転がす。【選択図】図9
