<p><P>PROBLEM TO BE SOLVED: To surely and rigidly fix an attachment body to a body to be attached by using wooden screws. <P>SOLUTION: In a hand rail bracket 100 as the attachment body employing the fixed structure, long-hole shaped penetration holes 123 are formed at the attachment body, the wooden screws 500 are screwed into the body to be attached via the penetration holes 123, and the attachment body is pressed against a wall surface W1 as the body to be attached by using seat faces 520 of the wooden screws 500. The penetration holes 123 are vertically formed with respect to the wall surface W1, a parallel contact face 126 parallel with the wall surface W1 and an inclined contact face 127 inclined with respect to the body to be attached are formed at upper end edges 125 of the penetration holes 123, and when shafts 530 of the wooden screws 500 are obliquely screwed into the body to be attached by making it contact with an upper end terminal point 127A at the side of the inclined contact face and with a lower end terminal point 126A at the side of the parallel contact face at an opposite side with the shafts 530 sandwiched therebetween, the seat faces 520 of the wooden screws 500 contact with the inclined contact face 127. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
