To provide a suction cup for generating strong suction force in which the vacuum force is increased only by the pressing force onto a suction surface, and a strong suction force is obtained even though a method for increasing the suction force of the suction cup or various kinds of operations have been required when detaching suction cups, and the suction force is released only by pressing a hooking member by the finger when the suction cups are removed.

A suction cup pushing bar (2) formed of a hard material is provided on a center portion on the inner side of a suction cup (1) formed of a flexible expandable material. A hooking bar (3) formed of a hard material is embedded in an outer center portion of the suction cup (1) to hook and fix a center portion of the suction cup (1) pushed up by the suction cup pushing bar (2) in the direction opposite to the pushing direction when the suction cup is pushed, and a hooking cylinder (5) and a hooking member (6) are provided on an upper portion of a pressing panel (4).
