A mounting sucker is adapted to be mounted on a smooth surface and composed of a suction devices (10), an intermediate member (20), and a rotating boss (30). When the rotating boss (30) is rotated, the central part of the suction devices (10) is pulled away from the smooth surface, creating a partial vacuum space. The intermediate member (20) pushes down on peripheral edges of the suction devices (10). An outer periphery of the rotating boss (30) extends beyond the range of the suction devices (10) so that the outer periphery of the rotating boss (30) can contact the smooth surface and transmit force from an object suspended on the mounting sucker.
