To minimize manufacturing cost, while enabling attachment-detachment to a sucking object, by easily separating a sucked sucker.

A sill part 1 is arranged in a shaft part of the sucker 3, and the tip of this sill part and a peripheral edge part B of the sucker are connected by a connecting belt 2. Thus, the sucked sucker can be easily separated by inclining the sill part in the opposite direction of the connecting belt in a sucked state of the sucker. The sill part is also designed so that a cross section becomes a T shape, and the attachment-detachment by sliding installation with the sucking object can be performed by arranging a female type slit opposed to this sucking object in the sucking object. Since integral molding can be performed by a single material, the manufacturing cost can be minimized.
