PROBLEM TO BE SOLVED: To provide a suction cup device capable of performing fast a work for sucking a suction cup against a surface to be sucked or a work for releasing sucked state and capable of arranging an instrument unit constituting a unit having the suction cup device on the upper surface of the suction cup device.SOLUTION: A suction cup device 1 has an operating member 6 that can be reciprocated in a direction crossing with a suction cup supporting shaft 3 and there is provided means for applying a tensile force to the suction cup supporting shaft 3 by moving the operating member 6 in a prescribed direction. Preferably, the suction cup device 1 has an operating member 6 that can be reciprocated and slidingly moved in a direction where it is crossed with the suction cup supporting shaft 3 and there is provided means for applying a tensile force to the suction cup supporting shaft 3 by sliding and moving the operation member 6 in a prescribed direction.SELECTED DRAWING: Figure 1 |
