PROBLEM TO BE SOLVED: To provide a sucker advantageous in mounting on a sucked face in a stable state with no backlash even when the sucked face is a curved face. SOLUTION: When a case 12 is gripped and pushed against the sucked face, a sucker 14 sucks the sucked face. When a dial 40 is operated to be rotated in this state and the case 12 is displaced downward, the lower ends of a plurality of abutting bodies 38 abut on the sucked face. When the dial 40 is further operated to be rotated, a central portion of the sucker 14 is displaced in the direction of leaving the sucked face to increase the suction of the sucker 14. Since a plurality of abutting portions 16 abut on the sucked face, the case is mounted on the sucked face in its rattling preventive state. Even when the sucked face is the curved face, the abutting bodies 38 separating one from another can reliably abut on the sucked face and so the case 12 can be stably mounted on the sucked face.
