（産業上の利用分野）
本考案は樹脂ナツトに関し、さらに詳しくは、
例えば自動車等のボデーに所定の部品を取付ける
ために、ボデーから突出したボルトに対してねじ
込んで固定される筒状の樹脂ナツトに関する。[Detailed description of the invention] (Field of industrial application) The invention relates to resin nuts.
The present invention relates to a cylindrical resin nut that is screwed into and fixed to a bolt protruding from the body, for example, in order to attach a predetermined part to the body of an automobile or the like.
（従来の技術）
従来、ねじ込み式の筒状の樹脂ナツトとして、
例えば第５図に示すナツト１がある。(Conventional technology) Conventionally, as a screw-in cylindrical resin nut,
For example, there is a nut 1 shown in FIG.
この筒状のナツト１の内周部は適当数の縦向き
の突条２を備えたスプライン状に形成されてい
る。そしてこれらの突条２は、ナツト１が予定さ
れた寸法のボルト３にねじ込まれた際にボルト３
の雄ねじと噛合う高さに設定されている。なお、
ナツト１の一端部には留め用のフランジ４を備え
た角形の頭部５が設けられている。 The inner periphery of this cylindrical nut 1 is formed into a spline shape with an appropriate number of vertical protrusions 2. These protrusions 2 are arranged so that when the nut 1 is screwed into the bolt 3 of the predetermined size, the bolt 3
It is set at a height that meshes with the external thread. In addition,
A square head 5 with a fastening flange 4 is provided at one end of the nut 1.
そしてこのようなナツト１の使用にあたつて
は、まず第６図のように部品６（例えば、自動車
用のパイプ保持具）の取付け孔７にボルト３を嵌
挿した状態で部品６をボデーパネル８にあてが
い、次いで筒状のナツト１を取付け孔７に内挿す

よつて雌ねじ状の横溝が切られるため、ナツト１
がボルト３に対して固定され、かかるナツト１の
フランジ４によつて部品６がボデーパネル８に取
付けられるようになつていた（第７図参照）。 When using such a nut 1, first insert the bolt 3 into the mounting hole 7 of the part 6 (for example, a pipe holder for an automobile), and then attach the part 6 to the body, as shown in FIG. The panel 8 was applied, and then the cylindrical nut 1 was inserted into the mounting hole 7 and screwed onto the bolt 3. At this time, each protrusion 2 of the nut 1 has a female thread-shaped horizontal groove cut by the male thread of the bolt 3, so the nut 1
was fixed to the bolt 3, and the part 6 was attached to the body panel 8 by the flange 4 of the nut 1 (see FIG. 7).
（考案が解決しようとする課題）
しかし、上記のボルト３は、場合により、各種
の塗料等が付着して、その径が実質的に設定値よ
り大きくなつていることがしばしばある。例え
ば、自動車のフロア下面のボデーパネル８に吹付
けられる塩ビゾル（塩化ビニルプラスチゾル）等
の塗料の一部がボルト３に付着している場合等で
ある。(Problem to be Solved by the Invention) However, in some cases, the bolt 3 is coated with various paints and the like, and its diameter is often substantially larger than the set value. For example, a part of the paint such as vinyl chloride sol (vinyl chloride plastisol) sprayed onto the body panel 8 on the lower surface of the floor of the automobile may be attached to the bolt 3.
このような場合、ナツト１をボルト３にねじ込
むためのトルクが著しく大きくなつて破壊トルク
と称される限界値を超え、ナツト１の内周部が雌
ねじを形成できない程にボルト３によつて削られ
るという不具合があつた。いわゆる「バカ」にな
つた状態である。このため、ナツト１がボルト３
から抜け易くなり、部品６の取付けに支障を来た
していた。 In such a case, the torque for screwing the nut 1 into the bolt 3 becomes extremely large and exceeds a limit value called the breaking torque, and the inner circumference of the nut 1 is ground by the bolt 3 to the extent that a female thread cannot be formed. I had a problem where it would appear. This is the state of being what is called an ``stupid'' person. Therefore, nut 1 becomes bolt 3.
It became easy to come off, which caused problems in installing part 6.
そこで本考案は、このような問題を解消するこ
とを課題とする。 Therefore, the present invention aims to solve such problems.
（課題を解決するための手段）
上記の課題を解決するための手段は、合成樹脂

前記樹脂ナツトの内周部における螺合部よりも
奥側の部分には、ボルトの雄ねじに係止する抜止
め用の爪を突出させた係止部を設けたことであ
る。(Means for Solving the Problems) The means for solving the above problems is to form a cylindrical shape using a synthetic resin material, and the inner periphery of the cylindrical part is provided with a cylindrical shape that, when screwed into the bolt, is attached to the external thread of the bolt. A resin nut is provided with a threaded part whose inner diameter is set so that a mating female thread is cut, and a part of the inner circumferential part of the resin nut on the back side of the threaded part is engaged with the male thread of the bolt. This is because a locking portion with a protruding claw for preventing removal is provided.
上記の手段において、螺合部は単に円孔状に形
成しても良く、縦向きの突条を備えたスプライン
状に形成しても良い。螺合部を円孔状に形成する

より大きい適宜な径となるように設定し、また螺
合部をスプライン状に形成する場合はその山径
（スプラインを構成する突条の頂部間の径）が上
記と同様の径となるように設定する。 In the above means, the threaded portion may be simply formed in the shape of a circular hole, or may be formed in the shape of a spline with vertical protrusions. If the threaded part is formed in a circular hole shape, the inner diameter should be set to an appropriate diameter smaller than the thread diameter of the bolt and larger than the root diameter, and if the threaded part is formed in a spline shape, the threaded part should be set to an appropriate diameter. The diameter (the diameter between the tops of the protrusions forming the spline) is set to be the same as above.
係止部には単数又は複数の抜止め用の爪を設け
る。複数の爪を設ける場合において、係止部の周
方向に沿つて複数に設けても良く、係止部の軸方
向に沿つて複数に設けても良い。 The locking portion is provided with one or more claws for preventing removal. In the case where a plurality of claws are provided, a plurality of claws may be provided along the circumferential direction of the locking portion, or a plurality of claws may be provided along the axial direction of the locking portion.

薄くなる。(Function) When screwing a nut into a bolt that has paint, etc. attached to it and has a diameter that is substantially larger than the set value,
First, the threaded part is screwed in. Even if the threaded part becomes loose, a considerable amount of the adhesion layer such as paint on the bolt surface will be stripped off by the threaded part.
Become thin.
然る後、係止部がボルトにねじ込まれるため、
抜止め用の爪が薄くなつた塗料等の付着層を破つ
てボルトの雄ねじに有効に係止する。 After that, the locking part is screwed into the bolt, so
The retaining claw breaks the thin adhesive layer of paint, etc. and effectively locks onto the male thread of the bolt.
（実施例）
次に本考案の一実施例を第１図〜第４図に基づ
いて説明する。(Example) Next, an example of the present invention will be described based on FIGS. 1 to 4.
樹脂製のナツト９は、留め用のフランジ１０を
備えた角形の頭部１１と、図の下方の入口側が開
口された筒状の軸部１２とを一体的に形成したも
のである。 The nut 9 made of resin is integrally formed with a rectangular head 11 provided with a fastening flange 10 and a cylindrical shaft portion 12 with an opening on the entrance side in the lower part of the figure.
軸部１２の内周部において、入口側の部分には
適当な数の縦向きの突条１３を備えたスプライン
状の螺合部１４が設けられている。このスプライ
ン状の螺合部１４は、その山径が予定している寸
法のボルト１５の山径と谷径との中間の適宜な径
とされ、またその谷径はボルト１５の山径より大
きく設定されている。 In the inner circumferential portion of the shaft portion 12, a spline-shaped threaded portion 14 having an appropriate number of vertical protrusions 13 is provided on the inlet side portion. This spline-shaped threaded portion 14 has a diameter that is suitable between the diameter of the peak and the valley of the bolt 15 having the planned size, and the diameter of the valley is larger than the diameter of the bolt 15. It is set.
一方、軸部１２の内周部の奥側の部分にはボル

6 are provided in multiple stages along the axial direction as shown in FIG. 3, and are provided in pairs with a constant width at opposing positions in the circumferential direction as shown in FIG. Each claw 16 is a relatively flat tongue protruding slightly diagonally upward, and protrudes at approximately the same height as the protrusion 13, as shown in FIG.
なお、軸部１２には、係止部１７の成形のため
の型抜き孔１８が残つている。 Note that a die-cut hole 18 for molding the locking portion 17 remains in the shaft portion 12 .
本実施例は以上のように構成されたものであ
り、その作用、効果を第３図および第４図に基づ
いて説明する。 The present embodiment is constructed as described above, and its functions and effects will be explained based on FIGS. 3 and 4.
自動車等の所定部分（例えば、フロア下面）を
構成するボデーパネル１９からは前記のボルト１
５が突出され、このボルト１５には塩ビゾル２０
が付着することにより、その径が実質的に設定値
より大きくなつている。 The aforementioned bolts 1
5 is protruded, and this bolt 15 is covered with PVC sol 20
As a result of the adhesion, the diameter becomes substantially larger than the set value.
このようなボルト１５を利用して、自動車用の
パイプ保持具等の任意の部品２１（一部のみを図
示する）をボデーパネル１９に取付けるにあた
り、まず第３図のように部品２１に設けた取付け
孔２２にボルト１５を嵌挿した状態で、部品２１
をボデーパネル１９にあてがう。 When attaching an arbitrary part 21 (only a part of which is shown), such as a pipe holder for an automobile, to the body panel 19 using such a bolt 15, first attach it to the part 21 as shown in Fig. 3. With the bolt 15 inserted into the mounting hole 22, the part 21
Apply to body panel 19.
次いでナツト９の軸部１２を、その入口側の部
分から、取付け孔２２に内挿する状態で、頭部１
１を利用したねじ込み操作によつてボルト１５に
対してねじ込む。 Next, insert the shaft part 12 of the nut 9 into the mounting hole 22 from the entrance side part, and insert the head part 1
1 by screwing into the bolt 15.
このとき、螺合部１４がまずねじ込まれるが、
ボルト１５が実質的に設定値より大径となつてい
るので、螺合部１５をねじ込むためのトルクがい
わゆる破壊トルク値を超え易く、この結果突条１
３がボルト１５の雄ねじによつて削られ、第４図
に示すように螺合部１４の山径が拡大してボルト
１５の雄ねじと有効に噛合う雌ねじ状の横溝を形
成できなくなる。即ち、螺合部１４がバカにな
る。 At this time, the threaded part 14 is screwed in first, but
Since the bolt 15 has a diameter substantially larger than the set value, the torque for screwing in the threaded part 15 easily exceeds the so-called breaking torque value, and as a result, the protrusion 1
3 is shaved off by the male thread of the bolt 15, and as shown in FIG. 4, the thread diameter of the threaded portion 14 expands, making it impossible to form a female thread-shaped lateral groove that effectively engages with the male thread of the bolt 15. In other words, the threaded portion 14 becomes dull.
しかしその際、塩ビゾル２０の付着層も螺合部
１４によつて、ほぼボルト１５の山径と等しくな
る程度にまで剥ぎ取られる（第４図参照）。かか
る状態のボルト１５は、その雄ねじの谷部にのみ
塩ゾビル２０が詰まつている状態であるため、螺
合部１４に続いて係止部１７がねじ込まれたと
き、爪１６によつて残存した塩ゾビル２０が比較
的容易に排除される。このため爪１６が第４図の
ようにボルト１５の雄ねじに有効に係止される。 However, at this time, the adhesive layer of the PVC sol 20 is also stripped off by the threaded portion 14 to an extent that is approximately equal to the thread diameter of the bolt 15 (see FIG. 4). In the bolt 15 in such a state, only the valley of the male thread is filled with salt Zovir 20, so when the locking part 17 is screwed in following the threaded part 14, the remaining part is removed by the claw 16. The salt Zovir 20 is relatively easily eliminated. Therefore, the pawl 16 is effectively engaged with the male thread of the bolt 15 as shown in FIG.
このように、螺合部１４がバカになる代償とし
て塩ゾビル２０が剥ぎ取られ、係止部１７の爪１
６による係止が確保されるのである。従つてナツ
ト９のボルト１５からの抜止めが確実に行なわれ
るため、フランジ１０の留め作用により部品２１
もボデーパネル１９に対して確実に取付けられる
のである。 In this way, the salt zovir 20 is peeled off to compensate for the screwing part 14 becoming dull, and the claw 1 of the locking part 17 is removed.
Thus, the locking by 6 is ensured. Therefore, since the nut 9 is reliably prevented from coming off from the bolt 15, the part 21 is secured by the fastening action of the flange 10.
can also be securely attached to the body panel 19.
なお、軸部１２の内周部の奥側部分に、前記係
止部１７に代えて螺合部１４と同様に構成された
スプライン状の部分やあるいは所定の内径の丸孔
部分を設けたとしても、ボルト１５の雄ねじの谷
部に塩ゾビル２０が詰まつていることから、必ず
しもボルト１５と有効に噛合わない。 Incidentally, suppose that a spline-shaped part configured in the same manner as the threaded part 14 or a round hole part with a predetermined inner diameter is provided in place of the locking part 17 on the inner peripheral part of the shaft part 12. However, since the trough of the male thread of the bolt 15 is filled with salt Zovir 20, it does not necessarily mesh with the bolt 15 effectively.
本考案の他の実施例として、前記の螺合部１４
を、ボルト１５の山径より小さく谷径より大きい
適宜な内径の丸孔状に形成しても良い。この場合
の作用、効果も前記の実施例と同様である。 As another embodiment of the present invention, the above-mentioned threaded portion 14
may be formed in the shape of a round hole with an appropriate inner diameter smaller than the crest diameter of the bolt 15 and larger than the trough diameter. The functions and effects in this case are also similar to those of the previous embodiment.
