Utility Model Registration No. 2553833

この発明が解決しようとする主たる問題点は、この種のクリップにおいて、留め付け対象物に対する留め付けとその解除とを繰り返し行っても、留め付け対象物に対するクリップの留め付け状態を維持させる機能が損なわれることのないようにする点にある。   The main problem to be solved by the present invention is that this type of clip has a function of maintaining the clip clamped state with respect to the fastening object even if the clip is repeatedly fastened and released. The point is to keep it intact.

前記課題を達成するために、この発明にあっては、クリップを、基部から突き出す軸部と、この軸部からこの軸部に略直交する向きに突き出す分岐部とを備えてなる入れ込み部を備えており、この入れ込み部の軸部の受け入れ部に分岐部の受け入れ部を連通させてなる留め付け対象物に形成された貫通穴にこの入れ込み部を入れ込んだ後の軸部を中心にした捻回操作によりこの留め付け対象物に留め付くクリップであって、
基部は弾性変形可能に構成されていると共に、この基部にこの基部の弾性変形操作を可能とする操作部が備えられているものとした。 In order to achieve the above-described object, the present invention includes a insertion portion including a shaft portion protruding from the base portion and a branch portion protruding from the shaft portion in a direction substantially orthogonal to the shaft portion. A screw centered on the shaft portion after the insertion portion is inserted into a through hole formed in an object to be fastened by connecting the receiving portion of the branch portion to the receiving portion of the shaft portion of the insertion portion. A clip that is fastened to the object to be fastened by a turning operation,
The base portion is configured to be elastically deformable, and the base portion is provided with an operation portion that enables an elastic deformation operation of the base portion.

かかる構成によれば、留め付け対象物の貫通穴に入れ込み部を入れ込ませた状態から前記捻回操作をなすことにより、基部を弾性変形させながら入れ込み部の分岐部とこの基部とで留め付け対象物を挟み付けてこの留め付け対象物に対してクリップの留め付けをなすことができる。この状態から、操作部を利用して基部を弾性変形させながら、前記捻回操作前の位置までクリップを再び捻回操作することでクリップの留め付けは解かれる。この留め付けの解除にあたり入れ込み部や基部は損耗することがない。   According to such a configuration, the twisting operation is performed from the state where the insertion portion is inserted into the through hole of the object to be fastened, and the base portion is elastically deformed and the branch portion of the insertion portion and the base portion are fastened. The clip can be fastened to the fastening object by sandwiching the object. From this state, the clip is unfastened by twisting the clip again to the position before the twisting operation while elastically deforming the base using the operation unit. When the fastening is released, the insertion portion and the base portion are not worn.

かかるクリップにおいて、基部に、所定の前記捻回位置で貫通穴に入り込む回り止め突起を形成させておくこともある。このようにした場合、留め付け対象物の貫通穴に入れ込み部を入れ込ませたときに、回り止め突起をこの留め付け対象物における貫通穴への入れ込み手前側の面に基部を弾性変形させながら押し当てさせることができる。この状態から前記捻回操作をなすと回り止め突起が貫通穴に入り込む位置での基部の弾性復帰によって回り止め突起は貫通穴内に入り込み、分岐部の前記引っかかりを解く向きへの回動が阻止される。これにより留め付け対象物に対するクリップの留め付け状態は安定的に維持される。この状態から、操作部を利用して回り止め突起を貫通穴から抜け出させるように基部を弾性変形させながら、前記捻回操作前の位置までクリップを再び捻回操作することでクリップの留め付けは解かれる。この留め付けの解除にあたり回り止め突起が貫通穴の穴縁によって傷付けられることはない。 In such a clip, the base may be provided with a detent protrusion that enters the through hole at the predetermined twisting position. In this case, when the insertion part is inserted into the through hole of the fastening object, the rotation prevention protrusion is elastically deformed to the surface on the near side of the fastening object into the through hole. It can be pushed. If the twisting operation is performed from this state, the anti-rotation protrusion enters the through-hole due to the elastic return of the base at the position where the anti-rotation protrusion enters the through-hole, and the rotation of the branching portion in the direction to release the catch is prevented The Thereby, the clip clamped state with respect to the clamped object is stably maintained. From this state, the clip can be fastened by twisting the clip again to the position before the twisting operation while elastically deforming the base so that the anti-rotation protrusion is pulled out of the through hole using the operation part. It will be solved. When the fastening is released, the anti-rotation protrusion is not damaged by the hole edge of the through hole.

前記回り止め突起を、基部における入れ込み部の形成側の圧接面部に形成させておくと共に、
操作部を、基部における圧接面部と反対の側であって、回り止め突起と略背中合わせとなる位置に形成させておくこともある。 The rotation preventing projection is formed on the pressure contact surface portion on the formation side of the insertion portion in the base portion, and
The operation portion may be formed on the side of the base opposite to the pressure contact surface portion and at a position that is substantially back-to-back with the anti-rotation protrusion.

このようにした場合、操作部を操作することで、貫通穴からスムースに回り止め突起を抜き出させることができると共に、この状態のままクリップを留め付けを解く位置まで捻回操作することができる。   In this case, by operating the operation portion, the rotation prevention protrusion can be smoothly extracted from the through hole, and the clip can be twisted to the position where the clip is released in this state. .

前記基部の圧接面部を、入れ込み部の軸部を吸盤中心とするように成形された吸盤状をなすように構成させておくこともある。   The pressure-contact surface portion of the base portion may be configured to have a suction cup shape formed so that the shaft portion of the insertion portion is centered on the suction cup.

このようにした場合、クリップの留め付け対象物への留め付け状態において、この留め付け対象物に形成された貫通穴を入れ込み部の入れ込み手前側において基部によって覆って塵埃や塵芥がこの側から入れ込み先側に入り込まないようにシールすることができる。   In this case, when the clip is fastened to the fastening object, the through hole formed in the fastening object is covered with the base on the front side of the insertion part, and dust or dust is introduced from this side. It can be sealed so as not to enter the front side.

この発明にかかるクリップにあっては、留め付け対象物に対する留め付けとその解除とを繰り返し行っても、回り止め突起が摩耗又は損耗することがなく、留め付け対象物に対するクリップの留め付け状態を維持させる機能は損なわれない。   In the clip according to the present invention, even if the fastening to the fastening object and the release thereof are repeatedly performed, the anti-rotation protrusion is not worn or worn, and the clip is fastened to the fastening object. The function to maintain is not impaired.

以下、図１〜図９に基づいて、この発明を実施するための最良の形態について説明する。ここで図１〜図５は実施の形態にかかるクリップＣの一例（第一例）を、図６および図７はその他の一例（第二例）を、図８および図９はそのさらに他の一例（第三例）を示している。   The best mode for carrying out the present invention will be described below with reference to FIGS. 1 to 5 show an example (first example) of the clip C according to the embodiment, FIGS. 6 and 7 show another example (second example), and FIGS. 8 and 9 show other examples. An example (third example) is shown.

なお、以下に説明するクリップＣにおける弾性変形特性を有すべき箇所へのこの特性の付与は、典型的には、かかるクリップＣをプラスチックの射出成型品とすることで容易に確保できる。   It should be noted that the provision of this characteristic to a portion that should have the elastic deformation characteristic in the clip C described below can be easily ensured by making the clip C typically a plastic injection-molded product.

この実施の形態にかかるクリップＣは、留め付け対象物Ｐに形成された貫通穴Ｈへの入れ込み部１を備えており、かかる貫通穴Ｈにこの入れ込み部１を入れ込んだ後の捻回操作によりこの留め付け対象物Ｐに留め付くものである。かかるクリップＣは、典型的には、一方側にかかる入れ込み部１を備えると共に、他方側に前記留め付け対象物ＰにクリップＣを介して取り付けられる他の留め付け対象物Ｐ’に対する留め付け部２を備えている。   The clip C according to this embodiment includes the insertion portion 1 into the through hole H formed in the fastening object P, and the twisting operation after the insertion portion 1 is inserted into the through hole H. By this, it is fastened to this fastening object P. Such a clip C typically includes an insertion portion 1 on one side and a fastening portion for another fastening object P ′ attached to the fastening object P via the clip C on the other side. 2 is provided.

図示の例では、かかるクリップＣは、軸状主体３の一端３ａ側に前記入れ込み部１を形成させ、この軸状主体３の他端３ｂ側に前記留め付け部２を形成させてなる。図示の例では、留め付け部２は、軸状主体３の他端３ｂとの間に間隔を開けて形成されたフランジ２ａと、この他端３ｂに一端を一体に連接させてフランジ２ａの側に突き出す弾性片２ｂとから構成されている。弾性片２ｂはその他端の外側にフランジ２ａの側を向いた掛合面２ｄを備えた掛合部２ｃを備えている。また、弾性片２ｂは掛合部２ｃの側に向かうに連れて軸状主体３から次第に離れるように形成されており、軸状主体３の直径方向両側にそれぞれ形成されている。そして、図示の例では、一対の弾性片２ｂ、２ｂの掛合部２ｃの掛合面２ｄの外端間のピッチよりも穴径をやや小さくすると共に、前記フランジ２ａを入り込ませない大きさの前記他の留め付け対象物Ｐ’に形成された貫通穴Ｈ’に、かかる留め付け部２をこの貫通穴Ｈ’にフランジ２ａが引っかかる位置まで入れ込ませることにより、かかる貫通穴Ｈ’の入れ込み先側の穴縁に前記入れ込み時に撓み込まされた弾性片２ｂの弾発によって前記掛合部２ｃの掛合面２ｄを掛合されるように位置づけさせることができ、これによりクリップＣはかかる他の留め付け対象物Ｐ’にワンタッチで留め付けられるようになっている。（図５、図６、図８）   In the illustrated example, the clip C has the insertion portion 1 formed on the one end 3 a side of the shaft-shaped main body 3 and the fastening portion 2 formed on the other end 3 b side of the shaft-shaped main body 3. In the illustrated example, the fastening portion 2 includes a flange 2a formed with a gap between the other end 3b of the shaft-shaped main body 3 and one end integrally connected to the other end 3b. It is comprised from the elastic piece 2b which protrudes. The elastic piece 2b includes a hooking portion 2c having a hooking surface 2d facing the flange 2a on the outer side of the other end. The elastic pieces 2b are formed so as to gradually move away from the shaft-shaped main body 3 toward the hooking portion 2c, and are formed on both sides in the diameter direction of the shaft-shaped main body 3, respectively. And in the example of illustration, while making a hole diameter a little smaller than the pitch between the outer ends of the engaging surface 2d of the engaging part 2c of a pair of elastic piece 2b, 2b, the said other of the magnitude | size which does not enter the said flange 2a By inserting the fastening portion 2 into the through-hole H ′ formed in the fastening object P ′ to the position where the flange 2a is caught in the through-hole H ′, the through-hole H ′ is inserted into the through-hole H ′. It is possible to position the engagement surface 2d of the engagement portion 2c to be engaged with the elastic piece 2b bent at the time of insertion into the hole edge of the engagement portion 2c. It can be fastened to P 'with one touch. (FIGS. 5, 6, and 8)

一方、図示の例では、前記入れ込み部１は、軸状主体３の一端３ａとの間に間隔を開けて形成された、この軸状主体３から側方に突き出す基部４と、この軸状主体３の一端３ａとの間に形成されている。すなわち、かかる入れ込み部１は、かかる基部４から突き出す軸状主体３の一部をなす軸部１ａを備えている。また、かかる入れ込み部１は、この軸部１ａからこの軸部１ａに略直交する向きに突き出す分岐部１ｂを備えている。   On the other hand, in the example shown in the drawing, the insertion portion 1 is formed with a space between the one end 3a of the shaft-shaped main body 3 and a base 4 protruding laterally from the shaft-shaped main body 3, and the shaft-shaped main body. 3 and one end 3a. That is, the insertion portion 1 includes a shaft portion 1 a that forms a part of the shaft-shaped main body 3 protruding from the base portion 4. Moreover, this insertion part 1 is provided with the branch part 1b which protrudes in the direction substantially orthogonal to this axial part 1a from this axial part 1a.

図示の例では、分岐部１ｂは軸部１ａの直径方向両側にそれぞれ形成されており、入れ込み部１は側面視でT字状をなすように構成されている。   In the illustrated example, the branch portions 1b are formed on both sides in the diameter direction of the shaft portion 1a, and the insertion portion 1 is configured to have a T shape in a side view.

そして、かかるクリップＣは、入れ込み部１の軸部１ａの受け入れ部Ｈａに分岐部１ｂの受け入れ部Ｈｂを連通させてなる留め付け対象物Ｐに形成された貫通穴Ｈに、この入れ込み部１を入れ込んだ後の軸部１ａを中心にした捻回操作により、入れ込み部１と基部４における入れ込み部１の形成側の圧接面部４ａとの間で留め付け対象物を挟み込んで、この留め付け対象物Ｐに留め付くように構成されている。   And this clip C has this insertion part 1 in the through-hole H formed in the fastening target object P which connects the reception part Hb of the branch part 1b to the reception part Ha of the axial part 1a of the insertion part 1. The object to be clamped is sandwiched between the inserting part 1 and the pressure contact surface part 4a on the forming side of the inserting part 1 in the base part 4 by a twisting operation around the shaft part 1a after being inserted. It is configured to be fastened to the object P.

図示の例では、留め付け対象物Ｐに形成された貫通穴Ｈは、入れ込み部１の外形に略倣った長穴状をなすように構成されている。貫通穴Ｈの長さ方向略中程の位置はやや幅広に構成されており、入れ込み部１はこの貫通穴Ｈの幅広部Ｈａ’に軸部１ａを位置させた状態でのみこの貫通穴Ｈに入れ込み可能となっている。   In the illustrated example, the through hole H formed in the fastening object P is configured to have a long hole shape that substantially follows the outer shape of the insertion portion 1. The position in the middle of the length of the through hole H is configured to be slightly wider, and the insertion portion 1 is formed in the through hole H only when the shaft portion 1a is positioned in the wide portion Ha ′ of the through hole H. It can be inserted.

留め付け対象物Ｐの貫通穴Ｈに入れ込み部１を入れ込ませた後に前記捻回操作をなすと分岐部１ｂが貫通穴Ｈへの入れ込み先側Ｆｗにおいて留め付け対象物Ｐに引っかかり貫通穴Ｈから入れ込み部１は抜き出されない状態となり、これによりクリップＣはかかる留め付け対象物Ｐに留め付けられるようになっている。このクリップＣの留め付け状態は、前記捻回操作前の位置までクリップＣを再び捻回操作することで解かれる。   When the twisting operation is performed after the insertion part 1 is inserted into the through hole H of the fastening object P, the branch part 1b is caught by the fastening object P at the insertion destination side Fw into the through hole H, and the through hole H Thus, the insertion portion 1 is not pulled out, so that the clip C is fastened to the fastening object P. The fastening state of the clip C can be solved by twisting the clip C again to the position before the twisting operation.

（図１〜図５に示される第一例）
図１〜図５に示されるクリップＣにあっては、前記基部４には、所定の前記捻回位置で貫通穴Ｈに入り込む回り止め突起４ｂが形成されていると共に、
貫通穴Ｈから回り止め突起４ｂを抜き出させる向きの基部４の弾性変形操作を可能とする操作部４ｃが備えられている。 (First example shown in FIGS. 1 to 5)
In the clip C shown in FIGS. 1 to 5, the base portion 4 is formed with a detent protrusion 4 b that enters the through hole H at the predetermined twisting position.
An operation portion 4c is provided that enables an elastic deformation operation of the base portion 4 in a direction in which the anti-rotation protrusion 4b is extracted from the through hole H.

図示の例では、基部４は軸状主体３を中心としてこの軸状主体３から張り出す円板状をなすように構成されている。回り止め突起４ｂはこの基部４における入れ込み部１の形成側の圧接面部４ａであって、この基部４の縁部に形成されている。回り止め突起４ｂは基部４の直径方向両側にそれぞれ設けられていると共に、一対の回り止め突起４ｂ、４ｂを通る仮想の直線に対し一対の分岐部１ｂの突きだし端を通る仮想の直線が交叉（図示の例では略直交）するように回り止め突起４ｂは形成されている。また、一対の回り止め突起４ｂ、４ｂはそれぞれ、基部４の周回方向に長く延びるリブ状をなすと共に、その長さを貫通穴Ｈの端部Ｈｂ’側の巾と略等しくするように構成されている。   In the illustrated example, the base 4 is configured to have a disk shape projecting from the shaft main body 3 with the shaft main body 3 as a center. The anti-rotation protrusion 4 b is a pressure contact surface portion 4 a on the formation side of the insertion portion 1 in the base portion 4, and is formed on an edge portion of the base portion 4. The anti-rotation protrusions 4b are provided on both sides in the diameter direction of the base portion 4, and a virtual straight line passing through the protruding ends of the pair of branch portions 1b intersects with an imaginary straight line passing through the pair of anti-rotation protrusions 4b and 4b ( The anti-rotation protrusion 4b is formed so as to be substantially orthogonal in the illustrated example. Each of the pair of anti-rotation protrusions 4b and 4b has a rib shape extending in the circumferential direction of the base portion 4 and is configured to have a length substantially equal to the width of the through hole H on the end portion Hb ′ side. ing.

一方、操作部４ｃは、基部４における圧接面部４ａと反対の側であって、回り止め突起４ｂと略背中合わせとなる位置にそれぞれ形成されている。各操作部４ｃは一端を基部４に一体に連接させて軸状主体３の他端３ｂ側に突き出す板片状をなすように構成されている。また、かかる回り止め突起４ｂと入れ込み部１における分岐部１ｂの基部４の側を向いた面間の入れ込み部１の入れ込み方向におけるピッチは、留め付け対象物Ｐの厚さよりやや小さくなるようにしてある。   On the other hand, the operation portion 4c is formed on the opposite side of the base portion 4 from the pressure contact surface portion 4a and at a position substantially back to back with the anti-rotation protrusion 4b. Each operation portion 4c is configured to have a plate-like shape in which one end is integrally connected to the base portion 4 and protrudes toward the other end 3b side of the shaft-shaped main body 3. In addition, the pitch in the insertion direction of the insertion portion 1 between the rotation-preventing protrusion 4b and the surface of the insertion portion 1 facing the base 4 side of the branching portion 1b is set to be slightly smaller than the thickness of the fastening object P. is there.

かかる構成によれば、留め付け対象物Ｐの貫通穴Ｈに入れ込み部１を入れ込ませきったときに、回り止め突起４ｂをこの留め付け対象物Ｐにおける貫通穴Ｈへの入れ込み手前側の面に基部４を弾性変形させながら押し当てさせることができる。この状態から前記捻回操作をなすと回り止め突起４ｂが貫通穴Ｈに入り込む位置での基部４の弾性復帰によって回り止め突起４ｂは貫通穴Ｈ内に入り込み、分岐部１ｂの前記引っかかりを解く向きへの回動が阻止される。（図３〜図５）これにより留め付け対象物Ｐに対するクリップＣの留め付け状態は安定的に維持される。この状態から、操作部４ｃを利用して回り止め突起４ｂを貫通穴Ｈから抜け出させるように基部４を弾性変形させながら、前記捻回操作前の位置までクリップＣを再び捻回操作することでクリップＣの留め付けは解かれる。この留め付けの解除にあたり回り止め突起４ｂが貫通穴Ｈの穴縁によって傷付けられることはない。   According to such a configuration, when the insertion portion 1 is completely inserted into the through hole H of the fastening object P, the surface on the near side of insertion of the rotation preventing projection 4b into the through hole H in the fastening object P is provided. The base 4 can be pressed while being elastically deformed. When the twisting operation is performed from this state, the anti-rotation projection 4b enters the through-hole H by the elastic return of the base portion 4 at the position where the anti-rotation projection 4b enters the through-hole H, and the direction in which the hooking of the branch portion 1b is released Rotation to is prevented. (FIGS. 3-5) Thereby, the fastening state of the clip C with respect to the fastening object P is maintained stably. From this state, by twisting the clip C again to the position before the twisting operation while elastically deforming the base 4 so that the anti-rotation protrusion 4b is pulled out from the through hole H using the operation portion 4c. The clip C is unfastened. When the fastening is released, the rotation preventing projection 4b is not damaged by the hole edge of the through hole H.

図示の例では、一対の操作部４ｃ、４ｃを同時に軸状主体３の側に近づける向きに操作することで、貫通穴Ｈからスムースに回り止め突起４ｂを抜き出させることができると共に、この状態のままクリップＣを留め付けを解く位置まで捻回操作できるようになっている。   In the example shown in the drawing, by operating the pair of operation parts 4c and 4c so as to approach the axial main body 3 side at the same time, the anti-rotation protrusion 4b can be smoothly extracted from the through hole H, and this state As a result, the clip C can be twisted to the position where the clip C is unfastened.

また、図示の例では、かかる基部４の圧接面部４ａは、入れ込み部１の軸部１ａを吸盤中心とするように成形された吸盤状をなすように構成されている。これにより図示の例では、クリップＣの留め付け対象物Ｐへの留め付け状態において、この留め付け対象物Ｐに形成された貫通穴Ｈを入れ込み部１の入れ込み手前側Ｂｗにおいて基部４によって覆って塵埃や塵芥がこの側から入れ込み先側Ｆｗに入り込まないようにシールするようになっている。   Further, in the illustrated example, the pressure contact surface portion 4a of the base portion 4 is configured to have a suction cup shape formed so that the shaft portion 1a of the insertion portion 1 is centered on the suction cup. Accordingly, in the illustrated example, in a state where the clip C is fastened to the fastening object P, the through hole H formed in the fastening object P is covered by the base 4 on the front side Bw of the insertion part 1. Sealing is performed to prevent dust and dust from entering from this side and into the destination side Fw.

（図６及び図７に示される第二例）
図６および図７に示されるクリップＣにあっては、前記基部４には、所定の前記捻回位置で貫通穴Ｈに入り込む回り止め突起４ｄが形成されていると共に、
入れ込み部１の分岐部１ｂには、留め付け対象物Ｐの一面側に弾性変形しながら接して、基部４を留め付け対象物Ｐの他面に押しつけるバネ手段１ｃが備えられている。 (Second example shown in FIGS. 6 and 7)
In the clip C shown in FIGS. 6 and 7, the base portion 4 is formed with a detent protrusion 4 d that enters the through hole H at the predetermined twisting position,
The branch portion 1b of the insertion portion 1 is provided with a spring means 1c that comes into contact with one surface side of the fastening object P while being elastically deformed and presses the base portion 4 against the other surface of the fastening object P.

図示の例では、基部４は軸状主体３を中心としてこの軸状主体３から張り出すように構成されている。回り止め突起４ｄはこの基部４における入れ込み部１の形成側であって、この基部４の縁部に形成されている。回り止め突起４ｄは基部４の直径方向両側にそれぞれ設けられていると共に、一対の回り止め突起４ｄ、４ｄを通る仮想の直線に対し一対の分岐部１ｂ、１ｂの突きだし端を通る仮想の直線が交叉（図示の例では略直交）するように回り止め突起４ｄは形成されている。   In the illustrated example, the base 4 is configured to project from the shaft-shaped main body 3 around the shaft-shaped main body 3. The anti-rotation protrusion 4 d is formed on the side of the base 4 where the insertion portion 1 is formed, and is formed on the edge of the base 4. The anti-rotation projections 4d are provided on both sides in the diameter direction of the base portion 4, and the virtual straight line passing through the protruding ends of the pair of branch portions 1b and 1b is different from the virtual straight line passing through the pair of anti-rotation projections 4d and 4d. The detent protrusion 4d is formed so as to cross (substantially orthogonal in the illustrated example).

バネ手段１ｃは、分岐部１ｂにおける基部４に向けられた側に形成されている。図示の例では、かかるバネ手段１ｃを、片両端をそれぞれ分岐部１ｂに一体に連接させ片中間部を弧状に張り出させたアーチ状をなす弾性帯状片１ｄとしている。かかる弾性帯状片１ｄの片中間部と回り止め突起４ｄとの間の入れ込み部１の入れ込み方向におけるピッチは、留め付け対象物Ｐの厚さより小さくなるようにしてある。   The spring means 1c is formed on the side of the branch portion 1b facing the base portion 4. In the illustrated example, the spring means 1c is formed as an elastic strip 1d having an arch shape in which both ends of the spring are integrally connected to the branching portion 1b and the middle portion of the piece projects in an arc shape. The pitch in the insertion direction of the insertion portion 1 between the middle portion of the elastic strip 1d and the anti-rotation projection 4d is set to be smaller than the thickness of the fastening object P.

かかる構成によれば、留め付け対象物Ｐの貫通穴Ｈに入れ込み部１を入れ込ませきった後、回り止め突起４ｄをこの留め付け対象物Ｐにおける貫通穴Ｈへの入れ込み手前側Ｂｗの面にバネ手段１ｃを弾性変形させて押し当てさせながら、前記捻回操作をなすことができる。この状態から回り止め突起４ｄが貫通穴Ｈに入り込む位置まで捻回操作がなされるとバネ手段１ｃの弾性復帰によって回り止め突起４ｄは貫通穴Ｈ内に入り込み、分岐部１ｂの前記引っかかりを解く向きへの回動が阻止される。これにより留め付け対象物Ｐに対するクリップＣの留め付け状態は安定的に維持される。この状態から、回り止め突起４ｄを貫通穴Ｈから抜け出させるようにバネ手段１ｃを弾性変形させながら、前記捻回操作前の位置までクリップＣを再び捻回操作することでクリップＣの留め付けは解かれる。この留め付けの解除にあたり回り止め突起４ｄが貫通穴Ｈの穴縁によって傷付けられることはない。   According to such a configuration, after the insertion portion 1 has been inserted into the through hole H of the fastening object P, the anti-rotation protrusion 4d is inserted into the through hole H of the fastening object P on the front side Bw surface. The twisting operation can be performed while elastically deforming and pressing the spring means 1c. When a twisting operation is performed from this state to a position where the detent projection 4d enters the through hole H, the detent projection 4d enters the through hole H due to the elastic return of the spring means 1c, and the direction of releasing the catch of the branch portion 1b. Rotation to is prevented. Thereby, the fastening state of the clip C with respect to the fastening object P is maintained stably. From this state, the clip C can be fastened by twisting the clip C again to the position before the twisting operation while elastically deforming the spring means 1c so that the anti-rotation protrusion 4d is pulled out of the through hole H. It will be solved. When the fastening is released, the anti-rotation protrusion 4d is not damaged by the hole edge of the through hole H.

（図８及び図９に示される第三例）
図８および図９に示されるクリップＣにあっては、前記入れ込み部１の分岐部１ｂには、所定の前記捻回位置で留め付け対象物Ｐに形成させた回り止め凹所Ｈｃに入り込む回り止め突起１ｅが形成されていると共に、
基部４には、留め付け対象物Ｐの一面に分岐部１ｂを押しつけるように、留め付け対象物Ｐの他面側に弾性変形しながら接するバネ手段４ｅが備えられている。 (Third example shown in FIGS. 8 and 9)
In the clip C shown in FIG. 8 and FIG. 9, the branch portion 1 b of the insertion portion 1 is rotated around the rotation-recessed recess Hc formed in the fastening object P at the predetermined twisting position. A stop projection 1e is formed,
The base 4 is provided with a spring means 4e that comes into contact with the other surface side of the fastening object P while being elastically deformed so as to press the branch portion 1b against one surface of the fastening object P.

図示の例では、基部４は軸状主体３を中心としてこの軸状主体３から張り出すように構成されている。バネ手段４ｅは、かかる基部４における軸状主体３を挟んだ両側であって入れ込み部１の形成側に形成されている。図示の例では、かかるバネ手段４ｅを、片両端をそれぞれ基部４に一体に連接させ片中間部を弧状に張り出させたアーチ状をなす弾性帯状片４ｆとしている。かかる弾性帯状片４ｆの片中間部と回り止め突起１ｅとの間の入れ込み部１の入れ込み方向におけるピッチは、留め付け対象物Ｐの厚さより小さくなるようにしてある。   In the illustrated example, the base 4 is configured to project from the shaft-shaped main body 3 around the shaft-shaped main body 3. The spring means 4e is formed on both sides of the base portion 4 with the shaft-like main body 3 interposed therebetween and on the side where the insertion portion 1 is formed. In the illustrated example, the spring means 4e is an elastic strip 4f having an arch shape in which both ends of the piece are integrally connected to the base 4 and the middle portion of the piece extends in an arc shape. The pitch in the insertion direction of the insertion portion 1 between the middle portion of the elastic strip 4f and the anti-rotation projection 1e is set to be smaller than the thickness of the fastening object P.

一方、回り止め突起１ｅは、一対の分岐部１ｂ、１ｂにおける基部４に向けられた側にそれぞれ形成されている。   On the other hand, the anti-rotation protrusion 1e is formed on the side of the pair of branch portions 1b and 1b facing the base portion 4, respectively.

回り止め凹所Ｈｃは、留め付け対象物Ｐにおける貫通穴Ｈへの入れ込み部１の入れ込み先側Ｆｗの面に形成されている。図示の例では、回り止め凹所Ｈｃは、貫通穴Ｈの幅広部Ｈａ’を挟んだ両側に形成されている。   The anti-rotation recess Hc is formed on the surface of the insertion destination side Fw of the insertion portion 1 into the through hole H in the fastening object P. In the example shown in the drawing, the rotation-preventing recess Hc is formed on both sides of the wide portion Ha 'of the through hole H.

かかる構成によれば、留め付け対象物Ｐの貫通穴Ｈに入れ込み部１を入れ込ませきった後、回り止め突起１ｅをこの留め付け対象物Ｐにおける貫通穴Ｈへの入れ込み先側Ｆｗの面にバネ手段４ｅを弾性変形させて押し当てさせながら、前記捻回操作をなすことができる。かかる捻回操作により回り止め突起１ｅが回り止め凹所Ｈｃに入り込む位置に至るとバネ手段４ｅの弾性復帰によって回り止め突起１ｅは回り止め凹所Ｈｃに入り込み、分岐部１ｂの前記引っかかりを解く向きへの回動が阻止される。これにより留め付け対象物Ｐに対するクリップＣの留め付け状態は安定的に維持される。この留め付けにあたり回り止め突起１ｅが貫通穴Ｈの穴縁によって傷付けられることはない。この状態から、回り止め突起１ｅを回り止め凹所Ｈｃから抜け出させるようにバネ手段４ｅを弾性変形させながら、前記捻回操作前の位置までクリップＣを再び捻回操作することでクリップＣの留め付けは解かれる。   According to such a configuration, after the insertion portion 1 has been inserted into the through hole H of the fastening object P, the rotation preventing protrusion 1e is inserted into the through hole H of the fastening object P on the surface of the insertion destination side Fw. The twisting operation can be performed while elastically deforming and pressing the spring means 4e. When the anti-rotation protrusion 1e reaches the position where it enters the anti-rotation recess Hc by such a twisting operation, the anti-rotation protrusion 1e enters the anti-rotation recess Hc by the elastic return of the spring means 4e, and the direction in which the above-mentioned catching of the branch portion 1b is released. Rotation to is prevented. Thereby, the fastening state of the clip C with respect to the fastening object P is maintained stably. In this fastening, the anti-rotation protrusion 1e is not damaged by the hole edge of the through hole H. From this state, the clip C is again twisted to the position before the twisting operation while elastically deforming the spring means 4e so that the anti-rotation protrusion 1e is pulled out of the non-rotating recess Hc. The date is solved.
