Zusammenfassung:PROBLEM TO BE SOLVED: To hold a fragile object, a ductile object, and a heavy object with one holding device.SOLUTION: Provided is an object holding method in a holding device 200 which includes a contact mechanism 100 having a contact member 101, a filling member 104 filled in the contact member 101 and having fluidity, filling pressure adjustment means 105 for adjusting the filling pressure and filling pressure detection means 141 for detecting the filling pressure, and holds an object 300 by bringing the contact mechanism 100 into contact with the object. The method includes: a preparation step for making the filling pressure in the contact member 101 a first charging pressure; a pressing force increase step for gradually increasing pressing force on the object 300 of the contact member 101; a specific filling pressure detection step for detecting specific filling pressure which is the filling pressure in a case in which the filling pressure is not increased even though the pressing force increase step is executed; and a holding step for holding the object 300 at the specific filling pressure or pressure less than the specific filling pressure but near the specific filling pressure.SELECTED DRAWING: Figure 2 【課題】脆性物体や延性物体、重量物を一つの挟持装置で保持する。【解決手段】当接部材101と、当接部材101の内方に充填される流動性を備えた充填部材104と、充填圧力を調整する充填圧力調整手段105と、充填圧力を検出する充填圧力検出手段141とを備える当接機構100を備え、対象物に当接機構100を当接させて対象物300を挟み持つ挟持装置200における対象物保持方法であって、当接部材101内の充填圧力を第一充填圧力にする準備ステップと、当接部材101の対象物300に対する押し付け力を徐々に増加させる押し付け力増加ステップと、押し付け力増加ステップを実行しているにもかかわらず、充填圧力の上昇が認められない時の充填圧力である特異充填圧力を検出する特異充填圧力検出ステップと、特異充填圧力、または、特異充填圧力未満であって特異充填圧力近傍の圧力で対象物300を保持する保持ステップとを含む。【選択図】図2
