に予じめ透孔を穿つてタツピングねじを使つてね
じ止めすることもあるが、金属板が肉薄であつた
り、強い緊締が必要な場合にはナツトを使つてボ
ルト締めすることが一般的である。[Prior art] When parts are fastened to a metal plate, through holes are sometimes drilled in the metal plate in advance and the screws are fastened using tapping screws. When this is necessary, bolts are generally tightened using nuts.

題となる。 The most important issue with this bolt tightening method is to fix the nut in the specified position, and in particular, from the viewpoint of workability and productivity on the assembly line, it is possible to set the nut quickly and reliably.
During tightening work, it is important to ensure that the nut does not shift its position or rotate together.

従来この様な場合に使用されるナツトを保持す
る手段として幾つかの提案がある。例えば本出願
人が提案する実開昭61−20911号公報記載のねじ
受け部材もその一つである。 There have been several proposals as means for holding nuts used in such cases. For example, the screw receiving member proposed by the present applicant and described in Japanese Utility Model Application No. 61-20911 is one such example.

この既提案に係るねじ受け部材はパネルを挟持

それ自体の製造性に優れる利点がある。 This screw receiving member according to the existing proposal has a holding part that accommodates a nut on one side of a pair of clamping pieces that sandwich a panel, and inserts the nut into the internal cavity through an insertion opening provided by cutting out one side wall of the holding part. It is designed to be assembled in a chamber, and is easy to attach to through holes drilled in metal plates, etc.
It has the advantage of excellent manufacturability.

が回転してしまうことがあつた。 However, one difficulty with this screw receiving member is that when a strong rotational torque is applied when tightening the bolt, the insertion opening of the holding portion opens and the nut housed in the internal cavity rotates together. In particular, when tightening with mechanical tools, sometimes more tightening torque than necessary is applied.
The wall of the holding part, which is molded from synthetic resin, was sometimes pushed open by the open part of the insertion opening, causing the housed nut to rotate.

ている。 The holding part 4 has a side wall surface 7 that matches the four hexagonal surfaces of the nut 2 to be accommodated, and the through hole 6a is formed on this side wall surface.
At the same time, the side wall surface portions corresponding to the other two surfaces are opened to form a nut insertion opening 8, and a hole 9 communicating with the through hole 6a is formed in the center so as to close the end surface of the side wall surface 7. A hollow chamber 11 for accommodating a nut is formed inside the plate 10. A pair of guide walls 12, 12 are provided extending outward from both opening edges of the insertion port 8 so as to oppose each other.

面しこれを保持することになる。 When the nut is attached, the guide wall 12 guides the nut, and at this time the split pieces 14 bend outward due to the action of the spring to allow the nut to enter, and after the attachment is completed, the locking claws 15 are engaged as described above to prevent the nut from coming out. The guide wall 12 cooperates with the side wall surface 7 to come into contact with the surface of the nut and hold it.

ると共に、このねじ受け部材を仮止めする。 As shown in Fig. 7, when screwing a component C, etc., the screw receiving member assembled with nuts in this way is first pressed from the edge of panel A and inserted between both clamping pieces 3a and 3b. Then, align the through hole a drilled in this panel with the screw hole of the nut 2 housed in the holding part 4 while aligning it with the through holes 6a and 6b. At this time, the claw 18 is hooked onto the edge of the through hole a for alignment, and the screw receiving member is temporarily fixed.

実に組付けられる利点がある。[Effects of the invention] The screw receiving member of the present invention is constructed and used as described above, and since the screw receiving member main body 1 is molded separately from the nut, the nut is inserted in advance. Compared to those manufactured with nuts, resin does not flow into the threaded holes of the nuts, and compared to the conventional type of nut assembly, the assembly process requires less effort and can be assembled easily and reliably. There are advantages that can be added.

とである。 In particular, when assembling the nut, it is only necessary to push it through the insertion opening 8 towards the empty space 11 in the holding part, and by pushing it in, the dividing piece 14 at the edge of the opening opens outward, allowing easy entry. In addition, since the locking pawl 15 holds the housing after it is restored, it does not escape arbitrarily, making it easier to work with than the conventional type. An even better feature is that there are guide walls 12 on both edges of the insertion slot, which guide the entry of the nut, but also hold it in contact with the outer surface of the nut after it is inserted, so it is strong against the nut when tightening the bolt. The objective is to effectively prevent co-rotation when rotational torque is applied.

とが可能となる。 In addition, when carrying out the implementation, reinforcing ribs 17 are integrally formed on the outer surfaces of two opposing side wall surfaces of the holding portion that accommodates the nut, and by restraining the outward deflection of these side wall surfaces, the holding force of the nut can be further increased. can be strengthened,
It becomes possible to more effectively prevent co-rotation by using a small amount of material.
