PURPOSE:To enable a bolt to be secured to a body and also simultaneously enable a space between the bolt and a guide rail to be sealed by securing the guide rail to the body after a caulking stud bolt has been pressed in and fitted into a hole which is drilled in the bottom of the guide rail. CONSTITUTION:When a guide rail 2 is secured to a body with a stud bolt 4 after the thread section 4b of the bolt 4 is inserted into a given hole in the guide rail 2, a support block 5 is placed under the guide rail 2. Then, the bolt 4 is pressed down by a punch 6 allowing a prepared hole correction ring 4d of the bolt 4 to expand the hole of the guide rail 2. Subsequently, the bolt 4 is further pressed down allowing the circumference of the hole to be sprung up and fitted into a holding groove 4c of the bolt 4 at the time when the ring 4d comes out of the hole of the guide rail 2. Then, the thread section 4b of the bolt 4 is inserted into a hole of the body and is fastened with a nut inside.
