PROBLEM TO BE SOLVED: To perform execution work even when it is difficult to use an adhesive under the execution work object surface by providing a curl plug which is embedded in the execution work object surface and can be deformed fanwise by insertion of a screw. SOLUTION: A display plate 4 having a circular shape in a plan view is molded so that the bottom surface becomes vertical to a screw 3 by implanting the head part of the tapping screw 3 in the center of the bottom part. Next, the screw 3 is fitted in a curl plug 2 by rotating the display plate 4 by hand by inserting the curl plug 2 into a prepared hole bored in the execution work object surface, and an adhesive is also preapplied to the bottom surface of the display plate 4. Next, when the curl plug 2 and the screw 3 are fitted together, a female screw to complement the screw 3 is formed on the inside surface of the curl plug 2 so that the curl plug 2 is fixed to the screw 3, and at the same time, the curl plug 2 is brought into pressure contact with an inner wall of the prepared hole by trying to be deformed fanwise by being push-split by the screw 3 to be fixed to the execution work object surface. Therefore, execution work can be performed even when it is difficult to use an adhesive under the execution work object surface. |
