A vacuum holder for holding articles by suction includes a vacuum chamber divided into a plurality of interconnected sub-chambers each communicating via a control a passageway with a plurality of suction openings extending through an outer holding surface, and a valve member for each control passageway integrally formed with a mounting section mounted to the housing, and an elastic juncture section normally biassing the valve member to open its respective control passageway to permit the application of suction to its plurality of suction openings. Each valve member is displaceable by the suction force applied from its respective vacuum sub-chamber, when its plurality of suction openings are not covered by the article to be held by the holder, to thereby close the control passageway to its respective suction openings.
