SUCTION PAD
FIG5B is an explanatory diagram of operations, showing a state in which the workpiece is attracted under suction and moved upwardly by the suction device of FIG5A
Then, as shown in FIG5B, in a state in which the workpiece W is attracted under suction by the suction device 10, by causing the workpiece W to be moved upwardly (in the direction of the arrow A) by the arm of the non-illustrated transport apparatus, the workpiece W becomes deformed so as to bend downward in the direction of gravity (the direction of the arrow B) due to the weight of the contents, and accordingly, the skirt 38 elastically deforms so as to follow the shape of the upper part of the workpiece W that is attracted under suction, and becomes a downwardly bent curved shape.

['5. The suction pad according to claim 1, wherein the suction member further comprises: an attachment (36) provided in a center of the suction member, and to which the negative pressure fluid is supplied; and a skirt (38) which is elastically deformable and disposed on an outer circumferential side of the attachment, the skirt having a suction surface configured to attract the workpiece under suction; wherein the skirt is disposed to be freely flexible about the attachment with the attachment acting as a supporting point.']
