For this reason, when the fixed screw is screwed into the light-weight steel material, the wiring box also rotates with the rotation of the fixed screw, and the fixing screw must be screwed into the light-weight steel material while holding the wiring box by hand. It was very troublesome. In view of this, a wiring box has been proposed in which a fixing screw is held on the bottom wall instead of the side wall of the wiring box (see, for example, Patent Document 2).

The wiring box (wiring instrument box) of Patent Document 2 is provided with holding means for fixing screws on the bottom wall. The holding means includes a support column erected from the bottom wall and a holding portion extended from the tip of the support column so as to be separated from the bottom wall. A hole through which the fixing screw can pass is formed in the holding part, and the opposite side of the holding part to the support column is a thin part. When the fixing screw is inserted into the hole of the holding portion, the fixing screw is held by the holding portion, and the fixing screw is attached to the wiring device box by the holding means. And when fixing the wiring box of patent document 2 to a lightweight shape steel material, a fixed screw is removed from a holding part, and when a fixed screw is screwed into a lightweight shape steel material, a wiring box rotates with rotation of a fixed screw. Is avoided.

The lightweight steel P is composed of an opening Pa extending in the standing direction, a back plate Pb opposite to the open Pa, and a pair of side plates Pc sandwiching the back plate Pb. The opening Pa is formed between a pair of opposing lip portions Pd extending from the pair of side plate portions Pc.

  The wiring box 10 is made of a synthetic resin material, and includes a box body 11 formed in a bottomed square box shape that opens on one surface. The box body 11 is formed of a bottom wall 12 having a square plate shape, and an upper side wall 13, a lower side wall 14, a left side wall 15, and a right side wall 16 as side walls standing from the periphery of the bottom wall 12. . On the inner surface of the left side wall 15, three recesses 15 b that are recessed toward the outer surface side of the left side wall 15 and that are elongated are formed at intervals in the vertical direction of the left side wall 15.

  In the left side wall 15, each recess 15b is formed with a fixing through-hole 15a that has a semicircular hole shape and penetrates the left-side wall 15 in the thickness direction. The recessed portion 15b formed in the upper portion of the left side wall 15 has one fixing through hole 15a, the recessed portion 15b formed in the central portion has two fixing through holes 15a, and the recessed portion 15b formed in the lower portion has One fixing through-hole 15a is formed.

  Each fixing through-hole 15a is formed so that a fixing screw 20 for fixing the wiring box 10 to the lightweight steel P can be inserted. As shown in FIG. 4A, the fixing screw 20 includes a screw portion 21 and a head portion 22, and the tip portion 21a of the screw portion 21 is formed so as to be pointed toward the tip from the screw portion 21. ing. Therefore, in the fixing screw 20, the diameter of the distal end portion 21 a is smaller than the diameter of the screw portion 21. As shown in FIG. 1, each fixing through hole 15 a is formed larger than the diameter of the screw portion 21 of the fixing screw 20. In addition, a gripping portion 23 projects outward from the left side wall 15 at the center in the vertical direction of the left side wall 15.

  On the bottom wall 12, screw holding means 30 are provided at positions near the inner surface of the left side wall 15 and facing the concave portions 15 b on both the upper and lower sides.

Further, when the screw portion 21 comes into contact with the contact step portion 33a, the fixing screw 20 tilts with the contact step portion 33a as a fulcrum.

  As shown in FIGS. 4C and 5, when the fixing screw 20 tilts, the distal end portion 21 a of the fixing screw 20 passes through the screw passage portion 35 from the screw hole 31 a (screw arrangement space), and further, It passes through the screw escape portion 32. For this reason, when the fixed screw 20 is tilted, the front end portion 21a is prevented from interfering with the bottom wall 12 and the screw screw-in portion 31. And when the front-end | tip part 21a passes the screw | thread escape part 32, the fixed screw | thread 20 can be removed from the screw | thread screwing part 31. FIG.

  After that, as shown in FIG. 6, while the outer surface of the left side wall 15 of the wiring box 10 is brought into contact with the lip portion Pd of the lightweight steel P, the fixing screw 20 is inserted into the fixing through hole 15a and forced into the lip portion Pd. Screwed in. At this time, since the fixing through hole 15a is larger than the diameter of the screw portion 21 of the fixing screw 20, the wiring box 10 is prevented from rotating with the rotation of the fixing screw 20. When the fixing screw 20 is screwed into the lip portion Pd, the wiring box 10 is fixed to the lightweight steel member P.
