Abstract
A suction cup device includes a suction cup, an adhesive polymer gel layer mounted to a suction surface of the suction cup and a case. A suction surface of the polymer gel layer includes a region on an outer peripheral side and a region on an inner peripheral side placed in a position deeper than an extending surface of the region on the outer peripheral side. The case includes, on an inner surface thereof, a rib formed into an annular shape concentric with the suction cup. The rib faces the region on the outer peripheral side of the polymer gel layer from the back surface of the suction cup. When the suction cup mounted with the polymer gel layer is in the suction state, the rib presses and abuts against the back surface of the suction cup by the negative pressure, and presses the region on the outer peripheral side of the polymer gel layer via the suction cup.
