PURPOSE: A vacuum absorber is provided to join an adhesive member on the bottom surface of an adsorption plate, thereby attaching an object easily and firmly to even a concavo-convex surface. CONSTITUTION: A vacuum absorber comprises a cover(10), an absorption plate(30), and a height adjusting member(20). The cover includes a plurality of fixtures(14) and a plurality of hanging protrusion units(120). The absorption plate is installed under the cover, and a central shaft is formed in the center of the top of the absorption plate. The height adjusting member includes an inner plate and a lateral plate. The inner plate includes a plurality of guide units and a plurality of elastic hanging pieces. A plurality of guide groove units where each guide unit is inserted is formed in the inner top surface of the cover. Hanging protrusion units sliding along the top of the each guide unit are respectively formed between the guide groove units. A joining groove unit is formed in a circumferential direction of the adsorption plate on the top surface of the adsorption plate.
