<p><P>PROBLEM TO BE SOLVED: To prevent an insulated circuit material from conducting through metal chips in an electrical connection box for securing a connector to a case through screwing, by arranging such that the metal chips produced, when a push nut for preventing removal of the bolt before tightening cuts the bolt, are small pieces. <P>SOLUTION: A circuit material is contained in a case and a connector 30 is arranged on the lower surface of the case. The connector 30 is secured to the case, by tightening a bolt 20 for a nut 31 secured to the connector 30 from above the case and the outer circumferential surface 20c-2 at the stopper portion 20c of the bolt 20 is made irregular. Furthermore, a push nut 21 is fixed to the bolt 20 from the tip end of shaft section, while going over the stopper portion 20c. Even if the claw portion 21b of the push nut 21 cuts off the outer circumferential surface of the stopper portion 20c at fixing of the push nut 21, it is cut off as a small piece. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
