To provide a negative pressure suction seal in which negative pressure suction function is not lost by a free end part being peeled, even when the negative pressure suction seal encounters a protrusion on an object surface, and which can reduce a frictional force between the free end part and the object surface.SOLUTION: A negative pressure suction seal 23 is constituted at least by a seal fixing part, a seal extention/contraction part connected to the seal fixing part, and a seal free end part connected to the seal extension/contraction part. The seal extension/contraction part is constituted at least by a portion which becomes narrower as it goes closer to an object surface from a portion connected to an inner edge part of the seal fixing part. The seal free end part is constituted by a portion which further expands to the outside from the inner edge part connected to the seal extension/contraction part. The seal fixing part is fixed to a sucker frame 22 via a seal fixing plate member. A position of the inner edge part of the seal fixing plate member is on the outside of a position of the inner edge part of the seal fixing part. A frictional force between the negative pressure suction seal and the object surface is adjusted by increasing/decreasing an area in which the seal fixing plate member holds down the seal fixing part.SELECTED DRAWING: Figure 7

    【課題】負圧吸着シールが物体表面にある突起に遭遇しても自由端部がめくれて負圧吸着機能を喪失しないように、また自由端部と物体表面との摩擦力を低減可能な負圧吸着シールを提供する。【解決手段】負圧吸着シール23はシール固定部とシール固定部に連結されたシール伸縮部とシール伸縮部に連結されたシール自由端部から少なくとも構成されており、シール伸縮部はシール固定部の内縁部に連結された部分から物体表面に近づくにつれ狭まった部分から少なくとも構成されており、シール自由端部はシール伸縮部に連結された内縁部からさらに外側に拡がった部分から構成されており、シール固定部はシール固定板部材を介して吸盤フレーム22に固定されており、シール固定板部材の内縁部の位置はシール固定部の内縁部の位置の外側にあり、シール固定板部材がシール固定部を押さえ付けている面積を増減することにより負圧吸着シールと物体表面との摩擦力を調整する。【選択図】図7
