<p>PROBLEM TO BE SOLVED: To enable the screwing of a bolt to a wall by forming a back surface part of a jacket of a wall, which is fixed to the periphery of an end of a cylindrical body in the inserting direction, of a cloth, which is hard to be drawn, and forming a front surface part of the jacket with a cloth, which is easy to be drawn, and using the hardend material for fitting. SOLUTION: A hardening material 27 is supplied from a hardening material filling port 18 into a jacket 8 through an opening and closing port 20, an opening and closing port 15 and a filling port 9 so as to expand the jacket 8. At this stage, since a back surface part 8b of the jacket 8 is formed of a cloth hard to be drawn, and a front surface part 8a thereof is formed of a cloth easy to be drawn, the front surface part 8a is drawn with the expansion of the jacket 8 so as to push the back surface part 8b of the jacket 8 to a back surface of a wall part for lock. Furthermore, when a hardening material cylinder and a hardening material nozzle 17 or a shutter nozzle 19 are removed and a claw parts 14 is rotated by a finger so that the filing port 9 is closed by the opening and closing port 15, the hardening material 27 is hardened. With this structure, an engaging bolt can be strongly screwed, an annular member can be strongly fitted, and the rotation prevention can be easily performed.</p> |
