Abstract
A suction device includes an adapter having a supply passage to which a negative pressure fluid is supplied, a bellows connected to a lower end of the adapter, and a pad member formed at the distal end of the bellows. The pad member has plural first and second ribs on a suction surface that attracts a workpiece under suction. The first ribs are disposed on an outer circumferential side of an attachment provided in the center of the pad member and extend toward the outer circumferential side. The second ribs are provided on an outer circumferential side of the first ribs, and are disposed in a circumferentially offset manner with respect to the first ribs. Additionally, between the respective first ribs which are disposed alongside one another in the circumferential direction of a skirt, supply paths are formed to which the negative pressure fluid is supplied from the attachment.
