<P>PROBLEM TO BE SOLVED: To provide a vacuum sucker capable of maintaining a vacuum state excellent in suction force, and convenient by making a pressure change visible. Ž<P>SOLUTION: The vacuum sucker is excellent in suction force since vacuum suction is more perfectly performed by the air flow control of first and second check valves when an adhesion cover body is pressed after a suction plate is adhered on a glass surface or a tile wall surface. The vacuum sucker is convenient and excellent in compression force since a sufficient stroke is secured in a cover body in the suction process, and can maintain a vacuum state for a long period of time by tension increased by an elastic member interposed between the cover body and the adhesion cover body.
