PROBLEM TO BE SOLVED: To easily remove a component when the component becomes unnecessary, and to hold airtightness, in the component when the component is used as an anchor by inserting the component into a prepared hole and expanding itself. SOLUTION: A female component wherein a nut of a screw diameter approximate to an elastic body hole diameter, having a cross sectional shape approximate to a prepared hole shape, is bonded to an end face of an elastic body tube having a similar shape thereto is prepared. Pull-out resistance force is obtained, by inserting the female component into the prepared hole, sandwiching an installed member between a head part of a male component and an elastic body part of the female component, fastening the male component, and expanding the elastic body part inside the prepared hole to tightly contact the elastic body with the inner face of the prepared hole. When the airtightness is required, the airtightness can be accomplished by closing one of holes of the nut to prevent leakage from a screw part. When loosening the male component, the expansion of the elastic body part is dissolved to allow the easy removal of all the components. COPYRIGHT: (C)2004,JPO
