PROBLEM TO BE SOLVED: To provide a pressure type adsorption mechanism which has excellent facility applicability, which can achieve improvement of an adsorption force and which can avoid occurrence of various troubles by sucking dust and oil adhered to an object.
SOLUTION: An adsorption mechanism includes an adsorption body 3 for adsorbing an object. The adsorption body 3 includes: an elastically deformable adsorption film for coming into contact with an object 1; pressure fluid supply means 4 for supplying a pressure fluid for deforming the adsorption film; and adsorption film deformation means for deforming the adsorption film by the pressure fluid from the pressure fluid supply means 4. The adsorption film, in a contact state with the object 1, is deformed to the side separating from the object by the pressure fluid being supplied from the pressure fluid supply means 4 to the adsorption film deformation means, and by the deformation of the adsorption film, a sealed space which is further decompressed than the outside is formed between itself and the object, and the adsorption body adsorbs the object.
