Abstract
Herein disclosed a suction cup including: a suction cup body having at least one surface having a gel, the surface being a suction surface; and an elastically deformable spring element provided in or on the suction cup body, having a concave shape so as to make the suction surface have a concave shape, and energizing a central part of the suction surface away from a surface to be sucked in the condition where the suction surface is in suction contact with the surface to be sucked, wherein the spring element is formed from a material having a modulus of elasticity higher than those of natural rubber and synthetic rubbers.

A suction cup, comprising:
- a suction cup body having at least one surface including a gel, said surface being a suction surface;
- and
- an elastically deformable spring element provided in or on said suction cup body, having a concave shape so as to make said suction surface have a concave shape, and energizing a central part of said suction surface away from a surface to be sucked in the condition where said suction surface is in suction contact with said surface to be sucked, wherein
- a surface on the other side in the thickness direction of said suction cup body is a convex back surface,
- said spring element is formed from a metal, a carbon material, or a fiber-reinforced plastic,
- said spring element is attached to said back surface, and
- said spring element includes a central hole and a net-like material which extends radially from the central hole.
A suction cup, comprising:
- a suction cup body having at least one surface including a gel, said surface being a suction surface;
- and
- an elastically deformable spring element provided in or on said suction cup body, having a concave shape so as to make said suction surface have a concave shape, and energizing a central part of said suction surface away from a surface to be sucked in the condition where said suction surface is in suction contact with said surface to be sucked,
- wherein a surface on the other side in the thickness direction of said suction cup body is a convex back surface, said spring element is formed from a metal, a carbon material, or a fiber-reinforced plastic, and said spring element is attached to said back surface, and
- wherein said spring element includes a net-like member obtained by fabricating an elastic thin bar member into a concave shape corresponding to said suction surface.
