Abstract:
1. A suction cup, comprising: a suction cup body including at least one integrated surface formed of synthetic resin gel, said at least one integrated 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 in a direction away from a surface to be sucked when said suction surface is in suction contact with said surface to be sucked, wherein said spring element is formed from a material having a modulus of elasticity higher than a modulus of elasticity of natural rubber and moduli of elasticity of synthetic rubbers, wherein said spring element includes a net member, the net member being an elastic thin bar member having a concave shape corresponding to said suction surface, and wherein the net member includes a first set of fibers and a second set of fibers, each fiber of the first set of fibers being substantially parallel to and separated by multiples of a first distance from each other, each fiber of the second set of fibers being substantially parallel to and separated by multiples of a second distance from each other, each fiber of the first set of fibers being attached to at least one of the fibers of the second set of fibers, and each fiber of the second set of fibers is attached to at least one fiber of the first set of fibers.
