<p><P>PROBLEM TO BE SOLVED: To provide a wiring box installation method and a wiring box which allow the user to insert tubes or cables into insertion holes after passing a wiring boss into a through hole, and can prevent the occurrence of nonconformity caused by enlargement by suppressing the enlargement of the through hole. <P>SOLUTION: At the first side wall 13a of the wiring box 11, an insertion hole 21, which enables the user to insert a corrugated conduit 10 by shifting the corrugated conduit 10 radially toward a bottom wall 12, is opened to the side of the bottom wall 12. At the bottom wall 12, a through hole 36, which enables the finger of user's hand to project out of the wiring box 11, is made continuously from the through hole 21. Then, the user inserts his hand into space 11a in a box, and projects the finger of the hand out of the wiring box 11 from the through hole 36, and hooks the finger to the corrugated conduit 10 arranged within a building wall W. Furthermore, the user draws near the corrugated conduit 10 to the side of the bottom wall 12 by shifting the hand to the outside of the building wall W, thus being able to insert the corrugated conduit 10 into the insertion hole 21. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
