本発明は、自動車のボデーパネル等に設けられた雌ねじ付きの穴を塞ぐ栓部材、すなわち、雌ねじ用穴塞ぎプラグに関する。   The present invention relates to a plug member for closing a hole with a female screw provided in a body panel of an automobile, that is, a female screw hole plug.

自動車のボデーパネルには、種々の部品等の取付けのために、溶接ナット等のナットを裏面に設けた雌ねじ付きの穴が設けられているが、部品を取付ける必要が無い雌ねじ付きの穴は、水やゴミや異物等の侵入防止のため、雌ねじ用穴塞ぎプラグで塞のが望ましい。   The body panel of an automobile is provided with a hole with a female thread in which a nut such as a welding nut is provided on the back surface for mounting various parts, etc. In order to prevent intrusion of water, dust, foreign matter, etc., it is desirable to plug with a female screw hole plug.

図１〜図４は、従来の雌ねじ用穴塞ぎプラグ及びその使用状態を示している。図１及び図２において、穴塞ぎプラグ１は、天然ゴム等の軟質ゴムあるいは軟質樹脂によって成形されて、ボデーパネル２の裏面に溶接された溶接ナット３のねじ穴及びボデーパネル２の穴４を塞ぐ。図３及び図４において、穴塞ぎプラグ５は、天然ゴム等の軟質ゴムあるいは軟質樹脂で、穴塞ぎプラグ１より大径に成形されて、図２のボデーパネル２より厚いボデーパネル６の穴７を塞ぐ。穴７のあるボデーパネル６の裏面には大径の溶接ナット８が溶接されており、穴塞ぎプラグ５は溶接ナット８のねじ穴も塞ぐ。   1 to 4 show a conventional female screw hole closing plug and its use state. 1 and 2, the hole closing plug 1 is formed of soft rubber such as natural rubber or soft resin, and has a screw hole of a welding nut 3 and a hole 4 of the body panel 2 welded to the back surface of the body panel 2.

雌ねじ用穴塞ぎプラグは、ボデーパネルの穴やナット穴を塞ぐ機能において、いくつか要件が要求される。（１）ナット穴への挿入時の嵌合性、（２）取付作業性、（３）嵌合後の振動等に伴なう脱落防止、（４）水密シール性、（５）取外し容易性、（６）取外し後の再使用性、が挙げられる。図１〜図４に図示の穴塞ぎプラグ１及び５は、軟質材料で形成されているため、上記（１）〜（３）において十分とはいえず、また、振動等によって脱落のおそれがあるので、（４）水密シール性においても十分でなかった。   The female screw hole closing plug has several requirements for the function of closing the hole and nut hole of the body panel. (1) Fitability when inserted into nut hole, (2) Mounting workability, (3) Prevention of dropout due to vibration after fitting, (4) Watertight sealability, (5) Ease of removal (6) Reusability after removal. Since the hole closing plugs 1 and 5 shown in FIGS. 1 to 4 are made of a soft material, they cannot be said to be sufficient in the above (1) to (3), and may drop off due to vibration or the like. Therefore, (4) watertight sealability was not sufficient.

特許文献１には穴塞ぎ用キャップが記載されている。この穴塞ぎ用キャップは、（４）水密シール性の点で十分でなく、（１）ナット穴への挿入時の嵌合性や（５）取外し容易性の点でも十分でなかった。特許文献２〜５には、パネル形状の被取付部材に別の取付部材を連結する、被取付部材の取付穴へ挿入する軸部と取付部材を押さえるフランジとを備え、軸部に弾性係止片を有する、留め具が記載されている。これらは、留め具であって、裏面に雌ねじが固着されたねじ穴を塞ぐ、雌ねじ用穴塞ぎプラグではない。   Patent Document 1 describes a hole closing cap. This cap for closing a hole is not sufficient in terms of (4) watertight sealability, and (1) fitability at the time of insertion into a nut hole and (5) ease of removal. Patent Documents 2 to 5 include a shaft portion that is inserted into a mounting hole of a mounted member and a flange that presses the mounting member, and is elastically locked to the shaft portion. A fastener having a piece is described. These are fasteners, and are not female screw hole closing plugs that close a screw hole having a female screw fixed to the back surface.

特許文献２の留め具は、軸部の弾性係止片の形状や寸法を変えることで差し込み力や除去力（取外し力）を選定しており、取外しが容易であれば、脱落防止力が弱まり、好ましくない。特許文献３の留め具は、ねじ穴に固定する留め具であるが、被取付部材が電柱等の比較的振動のない部材であり、嵌合後の振動等に伴なう脱落防止の点において十分であるとはいえない。特許文献４に記載の留め具は、取外しを容易にするため、軸部先端に弾性係止片を設け、その弾性係止片を特殊な形状に形成することを必要とする。特許文献５に記載の留め具は、内装材を傷つけずに取外しを容易にできるように形成されており、軸部の弾性係止片は、ねじ穴への係止を対象としていない。   In the fastener of Patent Document 2, the insertion force and removal force (removal force) are selected by changing the shape and dimensions of the elastic locking piece of the shaft portion. If removal is easy, the drop-off prevention force is weakened. Is not preferable. Although the fastener of patent document 3 is a fastener fixed to a screw hole, a to-be-attached member is a member without comparative vibrations, such as a utility pole, and in terms of prevention of dropout accompanying vibration after fitting. That's not enough. The fastener described in Patent Document 4 requires that an elastic locking piece is provided at the end of the shaft portion and that the elastic locking piece be formed in a special shape in order to facilitate removal. The fastener described in Patent Document 5 is formed so as to be easily removed without damaging the interior material, and the elastic locking piece of the shaft portion is not intended for locking into the screw hole.

従って、本発明の目的は、自動車のボデーパネル等に設けられた雌ねじ付きの穴を塞ぐ雌ねじ用穴塞ぎプラグを比較的簡単な構成で提供することにある。   Accordingly, an object of the present invention is to provide a female screw hole closing plug provided in a body panel or the like of an automobile for closing a female screw hole with a relatively simple configuration.

かかる目的を達成するため、本発明によれば、パネル等の被取付部材の裏面に固着された雌ねじ部材のねじ穴及び被取付部材の穴を塞ぐ、雌ねじ用穴塞ぎプラグであって、被取付部材の穴を塞ぐサイズのフランジと、フランジから垂下する支柱と、支柱の先端側からフランジに向け且つフランジに近づくにつれて支柱から離れるように延びる弾性係止片とからなり、支柱及び弾性係止片を被取付部材の穴及びねじ穴に挿入すると、弾性係止片の先端がねじ穴のねじ山に係止して、フランジが被取付部材の穴を塞ぐ、ことを特徴とする穴塞ぎプラグが提供される。   In order to achieve such an object, according to the present invention, there is provided a female screw hole closing plug for closing a screw hole of a female screw member fixed to the back surface of a member to be attached such as a panel and a hole of the member to be attached. A flange having a size that closes a hole of the member, a column that hangs down from the flange, and an elastic locking piece that extends from the distal end side of the column toward the flange and moves away from the column as it approaches the flange. Is inserted into the hole of the attached member and the screw hole, the tip of the elastic locking piece is engaged with the thread of the screw hole, and the flange closes the hole of the attached member. Provided.

上記穴塞ぎプラグによって、自動車のボデーパネル等に設けられた雌ねじ付きの穴を塞ぐ雌ねじ用穴塞ぎプラグを比較的簡単な構成で提供できる。   With the hole closing plug, a female screw hole closing plug for closing a hole with an internal thread provided in a body panel or the like of an automobile can be provided with a relatively simple configuration.

前記の穴塞ぎプラグにおいて、弾性係止片は、支柱の先端付近に設けられた、一対の下部弾性係止片と、支柱の中間高さ位置に設けられた、一対の上部弾性係止片とから成る。その場合、穴塞ぎプラグは、硬質合成樹脂で一体成形されており、下部弾性係止片の根元部に隣接して、下部弾性係止片の先端が支柱の先端側に旋回できる空間が、支柱に形成されるのが好ましい。これによって、下部弾性係止片がねじ穴を貫通しても、穴塞ぎプラグをの取外しにおいて、下部弾性係止片をほぼ１８０度旋回させることができ、破損なく取外しできるので、穴塞ぎプラグの再使用を可能にする。   In the hole closing plug, the elastic locking pieces include a pair of lower elastic locking pieces provided in the vicinity of the tip of the column, and a pair of upper elastic locking pieces provided at an intermediate height position of the column. Consists of. In that case, the hole closing plug is integrally formed of a hard synthetic resin, and a space where the tip of the lower elastic locking piece can turn to the tip side of the column is adjacent to the base of the lower elastic locking piece. Is preferably formed. Thereby, even if the lower elastic locking piece penetrates the screw hole, the lower elastic locking piece can be turned almost 180 degrees in removing the hole closing plug and can be removed without breakage. Enable reuse.

弾性係止片は、支柱の先端付近に設けられた、一対の下部弾性係止片と、支柱の中間高さ位置に設けられた、一対の中間弾性係止片と、中間弾性係止片よりフランジに近い位置に設けられた、一対の上部弾性係止片とを包含する。その場合、穴塞ぎプラグは軟質合成樹脂で一体成形されているのが好ましい。これによって、下部弾性係止片や中間弾性係止片がねじ穴を貫通しても、穴塞ぎプラグをの取外しにおいて、下部弾性係止片及び中間弾性係止片をほぼ１８０度旋回させることができ、破損なく取外しできるので、穴塞ぎプラグの再使用を可能にする。   The elastic locking piece includes a pair of lower elastic locking pieces provided near the tip of the support, a pair of intermediate elastic locking pieces provided at an intermediate height position of the support, and an intermediate elastic locking piece. And a pair of upper elastic locking pieces provided at positions close to the flange. In that case, the hole closing plug is preferably integrally formed of a soft synthetic resin. As a result, even if the lower elastic locking piece or the intermediate elastic locking piece penetrates the screw hole, the lower elastic locking piece and the intermediate elastic locking piece can be rotated by approximately 180 degrees when the hole closing plug is removed. And can be removed without breakage, allowing the plugging plug to be reused.

フランジの上面に、フランジを支柱の軸心回りに回転させる突条が形成されている。突条には、工具先端又は紐等を通す穴が形成されているのが好ましい。これとは別に、フランジの上面に、フランジを支柱の軸心回りに回転させるための十字溝が形成されているのが好ましい。その場合、十字溝は、フランジ上面に一体成形された十字溝形成部に形成されており、十字溝形成部とフランジとの間には、工具先端を挿入できる隙間が形成されているのが好ましい。これらの構成によって、穴塞ぎプラグの取外しの際にフランジを支柱の軸心回りに回転させるのが容易になり、穴塞ぎプラグの取外しを容易にする。 On the upper surface of the flange, a ridge that rotates the flange around the axis of the column is formed. The ridge is preferably formed with a hole through which the tool tip or string or the like passes. Apart from this, it is preferable that a cross groove for rotating the flange around the axis of the support column is formed on the upper surface of the flange. In that case, it is preferable that the cross groove is formed in a cross groove forming portion integrally formed on the upper surface of the flange, and a gap into which the tool tip can be inserted is formed between the cross groove forming portion and the flange. . With these configurations, when removing the hole closing plug, the flange can be easily rotated around the axis of the support column, and the hole closing plug can be easily removed.

以下、本発明のいくつかの好ましい実施形態について図面を参照して説明する。図５〜図１５には、自動車のボデーパネル等の被取付部材の裏面に固着された雌ねじ部材のねじ穴及び被取付部材の穴を塞ぐ、第１実施形態に係る雌ねじ用穴塞ぎプラグ１１が示されている。穴塞ぎプラグ１１は、熱可塑性合成樹脂で一体成形されている。かかる熱可塑性合成樹脂材料は、比較的硬質の合成樹脂材料であるのが好ましく、穴へ挿入するときの嵌合が確実になり、フィット感が得られる。穴塞ぎプラグ１１は、円盤の吸盤形状のフランジ１３と、フランジ１３の下面中央から垂下する支柱１４と、支柱１４からフランジ１３に向けて且つフランジ１３に近づくにつれて支柱１４から離れるように延びる、２対の弾性係止片１５及び１７とから成る。図５〜図１１には、穴塞ぎプラグ１１の構成が示されており、図１２〜図１５は、穴塞ぎプラグ１１が、被取付部材としてのボデーパネル２６穴２９及び雌ねじ部材としての溶接ナット２７のねじ穴３０を塞いだ状態を示している。   Several preferred embodiments of the present invention will be described below with reference to the drawings. 5 to 15 show a female screw hole closing plug 11 according to the first embodiment that closes a screw hole of a female screw member fixed to a back surface of a member to be attached such as an automobile body panel and a hole of the member to be attached. It is shown. The hole closing plug 11 is integrally formed of a thermoplastic synthetic resin. Such a thermoplastic synthetic resin material is preferably a relatively hard synthetic resin material, which ensures a good fit when inserted into the hole and provides a fit. The hole closing plug 11 has a disk-shaped suction cup-shaped flange 13, a column 14 that hangs down from the center of the lower surface of the flange 13, and extends away from the column 14 toward the flange 13 from the column 14 toward the flange 13. It consists of a pair of elastic locking pieces 15 and 17. 5 to 11 show the configuration of the hole closing plug 11. FIGS. 12 to 15 show the hole closing plug 11 as a body panel 26 hole 29 as a member to be attached and a welding nut as a female screw member. 27 shows a state where 27 screw holes 30 are closed.

フランジ１３は、全体として円盤形状に形成され、下面は、ボデーパネル等の雌ねじ付きの穴を塞いで密閉できるように薄肉の吸盤形状に形成されている。フランジ１３の上面は、指等で押込みが容易にできるように、全体としてほぼ平たい円盤形状に形成されている。また、穴塞ぎプラグ１１を穴から取外す場合、指等で、穴塞ぎプラグ１１を支柱１４の軸心回りに回転できるように、直径方向に細い幅で延びる、上方に突出した突条１８が形成されている。突条１８には、中央の部分に突条１８を貫通する穴１９が形成されている。穴１９には、スクリュードライバ等の工具の先端が挿入でき、穴塞ぎプラグ１１を、工具先端で引上げるのを可能にしている。この穴１９には、紐や針金等を挿入して、取外し時の引上げに利用することもできる。なお、フランジ１３の上面は、外縁部に向かって広く平坦に大きく形成されて、指先で押込むとき、指先へ痛みを感じないように形成されている。特に、突条１８がフランジ１３の外縁部に向かうにつれて平面視において幅広になるように形成されて、突条１８の突出による指先への痛みを感じないように形成されている。また、突条１８は、フランジ１３の全体の強度を増しており、雌ねじ穴の密閉機能が強化される。   The flange 13 is formed in a disk shape as a whole, and the lower surface is formed in a thin suction cup shape so as to close and seal a hole with a female thread such as a body panel. The upper surface of the flange 13 is formed in a substantially flat disk shape as a whole so that it can be easily pushed in with a finger or the like. Further, when the hole closing plug 11 is removed from the hole, an upward protruding protrusion 18 extending in a narrow width in the diameter direction is formed so that the hole closing plug 11 can be rotated around the axis of the support column 14 with a finger or the like. Has been. In the ridge 18, a hole 19 that penetrates the ridge 18 is formed in a central portion. The hole 19 can be inserted with a tip of a tool such as a screw driver, and the hole closing plug 11 can be pulled up by the tip of the tool. A string, a wire, or the like can be inserted into the hole 19 and used for pulling up at the time of removal. In addition, the upper surface of the flange 13 is formed so as to be large and flat toward the outer edge portion, and is formed so as not to feel pain to the fingertip when pushed by the fingertip. In particular, the protrusion 18 is formed so as to become wider in plan view as it goes toward the outer edge of the flange 13, and is formed so as not to feel pain to the fingertip due to the protrusion of the protrusion 18. Further, the protrusion 18 increases the overall strength of the flange 13, and the sealing function of the female screw hole is enhanced.

支柱１４は、フランジ１３の中心から垂下する棒状に形成されている。支柱１４は、フランジ１３に隣接する上部が、ボデーパネル等の穴を塞ぐ円柱部分２１として形成されている。円柱部分２１の直径は、ボデーパネル等の穴に入ってその穴の軸心と支柱１４の軸心とを合わせことができる大きさの円柱形状であるのが好ましい。穴塞ぎプラグ１１は、種々の大きさのねじ穴を塞ぐのに利用できるように、円柱部分２１の直径は、可能なねじ穴の最小の内径に合わせて形成されるのが好ましい。円柱部分２１より下方の支柱１４の部分には、２対の、下部弾性係止片１５及び上部弾性係止片１７が形成されている。円柱部分２１より下方の支柱部分は、支柱１４の強度を維持する厚さではあるが、各弾性係止片１５、１７が支柱１４側に撓んでもそれらを収容できる空間を形成するように、円柱の両側を削って薄く形成したような板状体として形成されている。支柱１４の先端（下端）には、挿入穴より十分に小径で且つその穴へ容易に導けるように先細に形成されたガイド２２が形成されている。ガイド２２は、小径の半球形状等の滑らかな形状に形成され、穴への導入を容易にするとともに、先端が作業者へ傷つけるのを防止している。   The support column 14 is formed in a rod shape that hangs down from the center of the flange 13. The column 14 has an upper portion adjacent to the flange 13 formed as a cylindrical portion 21 that closes a hole such as a body panel. The diameter of the cylindrical portion 21 is preferably a cylindrical shape that can enter the hole of the body panel or the like so that the axial center of the hole and the axial center of the column 14 can be aligned. The diameter of the cylindrical portion 21 is preferably formed to the smallest possible inner diameter of the screw hole so that the hole closing plug 11 can be used to close screw holes of various sizes. Two pairs of a lower elastic locking piece 15 and an upper elastic locking piece 17 are formed in the portion of the column 14 below the cylindrical portion 21. The column portion below the column portion 21 has a thickness that maintains the strength of the column 14, but forms a space that can accommodate them even if each elastic locking piece 15, 17 is bent toward the column 14 side. It is formed as a plate-like body that is formed by thinning both sides of a cylinder. A guide 22 that is sufficiently smaller in diameter than the insertion hole and tapered so as to be easily guided to the hole is formed at the tip (lower end) of the column 14. The guide 22 is formed in a smooth shape such as a small-diameter hemispherical shape, and facilitates introduction into the hole and prevents the tip from being damaged by the operator.

弾性係止片１５、１７は、図示の実施形態においては、支柱１４の下端部のガイド２２に近い位置に下部弾性係止片１５が一対形成され、下部弾性係止片１５より上方の、支柱１４の中間高さ位置に、上部弾性係止片１７が一対形成されている。下部弾性係止片１５と上部弾性係止片１７とが２段に形成されているので、雌ねじが固着されたボデーパネル等の部材の厚さが違っていても、その厚さの違いに対応してねじ穴を塞ぐことができる。各弾性係止片１５、１７は、図５、図７、図１０等に見られるように、なんら力が作用しない場合には支柱１４から斜め上方に向けた姿勢にある。各弾性係止片１５、１７は、雌ねじ穴等の穴へ挿入されるときに受ける穴の内壁面からの力によって支柱１４の側へ倒れる可撓性を有し、倒された場合に図５等の元の姿勢に復帰する弾性を有する。各弾性係止片１５、１７の先端は、雌ねじ穴に形成されたねじ山に係止する形状に形成されている。   In the illustrated embodiment, the elastic locking pieces 15, 17 are formed with a pair of lower elastic locking pieces 15 at positions close to the guide 22 at the lower end portion of the column 14, and the columns above the lower elastic locking piece 15. A pair of upper elastic locking pieces 17 are formed at the intermediate height position 14. Since the lower elastic locking piece 15 and the upper elastic locking piece 17 are formed in two steps, even if the thickness of the member such as the body panel to which the female screw is fixed is different, it corresponds to the difference in thickness. Thus, the screw hole can be closed. As seen in FIGS. 5, 7, 10, etc., each elastic locking piece 15, 17 is in a posture directed obliquely upward from the column 14 when no force is applied. Each of the elastic locking pieces 15 and 17 has the flexibility to fall to the side of the support column 14 due to the force from the inner wall surface of the hole received when inserted into a hole such as a female screw hole. It has elasticity to return to the original posture. The tip of each elastic locking piece 15, 17 is formed in a shape that is locked to a screw thread formed in the female screw hole.

下部弾性係止片１５の根元部２３には、下部弾性係止片１５がその根元部２３をヒンジとして、ほぼ１８０度旋回できる（図１３参照）ように、下方に旋回可能な空間２５が形成されている。本実施形態において、穴塞ぎプラグ１１が比較的硬質の合成樹脂で形成されているため、下方に旋回する自由度が低く、上部弾性係止片１７の根元部のように空間２５が無い場合には、下方への旋回を強制された場合、弾性係止片が破損するおそれがある。図１２に示すように、穴塞ぎプラグ１１が取付けられるボデーパネル２６の厚さが薄く且つ溶接ナット２７の高さが低い場合、穴塞ぎプラグ１１をパネル穴２９とねじ穴３０とに挿入すると、上部弾性係止片１７は溶接ナット２７のねじ穴３０に係止するが、下部弾性係止片１５は、溶接ナット２７を貫通してナット裏面側に延び出てしまう。取付けた穴塞ぎプラグ１１を穴から取外す場合、図１３に図示のように、下部弾性係止片１５は根元部２３に空間２５が形成されているため、下方にほぼ１８０度旋回することができ、穴塞ぎプラグ１１の取外しを行える。従って、穴塞ぎプラグ１１が比較的硬質の合成樹脂で形成されていても、穴塞ぎプラグ１１を破損することなく取外しでき、再使用が可能になる。   A space 25 that can be swung downward is formed in the base portion 23 of the lower elastic locking piece 15 so that the lower elastic locking piece 15 can turn about 180 degrees using the root portion 23 as a hinge (see FIG. 13). Has been. In the present embodiment, since the hole closing plug 11 is formed of a relatively hard synthetic resin, the degree of freedom of turning downward is low, and there is no space 25 as in the root portion of the upper elastic locking piece 17. If forced to turn downward, the elastic locking piece may be damaged. As shown in FIG. 12, when the thickness of the body panel 26 to which the hole closing plug 11 is attached is thin and the height of the welding nut 27 is low, when the hole closing plug 11 is inserted into the panel hole 29 and the screw hole 30, The upper elastic locking piece 17 is locked in the screw hole 30 of the welding nut 27, but the lower elastic locking piece 15 penetrates the welding nut 27 and extends to the nut back surface side. When the attached hole closing plug 11 is removed from the hole, as shown in FIG. 13, since the space 25 is formed in the root portion 23, the lower elastic locking piece 15 can be swung downward by approximately 180 degrees. The hole closing plug 11 can be removed. Therefore, even if the hole closing plug 11 is formed of a relatively hard synthetic resin, the hole closing plug 11 can be removed without being damaged and can be reused.

穴塞ぎプラグ１１の挿入力は、人間工学（ergonomics)的に作業者に負担が重くならないように３０Ｎ以下に定められるのが好ましく、これに合わせて、下部弾性係止片１５及び上部弾性係止片１７の弾性が定められるのが好ましい。図１１（Ｂ）に示すように、各弾性係止片１５、１７は、先端の角部分３１が丸く形成されるのが好ましく、これによって、ねじ穴への過度の係止を防止でき、例えば、取外しの際の穴塞ぎプラグ１１の軸心回りの回転を容易にし、取付け時の増し締めを容易にする。図１１（Ｃ）に示すように、各弾性係止片１５、１７の半径方向にみて外側の外面３３は断面において湾曲して形成されている。これによって、穴塞ぎプラグ１１の挿入時の接触抵抗を低下でき、作業者への負担を軽減する。   The insertion force of the hole closing plug 11 is preferably set to 30 N or less so as not to increase the burden on the worker in terms of ergonomics, and in accordance with this, the lower elastic locking piece 15 and the upper elastic locking piece The elasticity of the piece 17 is preferably defined. As shown in FIG. 11 (B), each elastic locking piece 15, 17 is preferably formed with a rounded corner portion 31 at the tip, which can prevent excessive locking to the screw hole, for example, In this case, the hole closing plug 11 can be easily rotated around the axial center during removal, and retightening during attachment can be facilitated. As shown in FIG. 11 (C), the outer surface 33 on the outer side as viewed in the radial direction of the elastic locking pieces 15 and 17 is formed to be curved in cross section. Thereby, the contact resistance at the time of insertion of the hole closing plug 11 can be reduced, and the burden on the operator is reduced.

上記構成で成る穴塞ぎプラグ１１が、裏面に溶接ナット２７が固着されている被取付部材としてのボデーパネル２６のパネル穴２９及び雌ねじ部材としての溶接ナット２７のねじ穴３０を塞いだ状態を、図１２に示す。穴塞ぎプラグ１１の取付けにおいて、支柱１４の先端のガイド２２がボデーパネル２６の穴２９及び溶接ナット２７のねじ穴３０に位置合わせされ、フランジ１３の上面が指で押圧されてそのまま支柱１４が押込まれ、下部弾性係止片１５及び上部弾性係止片１７が半径方向内側に倒される。フランジ１３の下面がボデーパネル２６に接面するまで押込まれると、パネル穴２９及びねじ穴３０がフランジ１３で塞がれる。図１２の例は、ボデーパネル２６が薄いパネルであり、溶接ナット２７も軸方向長さ（高さ）が短い。従って、フランジ１３がボデーパネル２６に接面した状態では、下部弾性係止片１５が溶接ナット２７を貫通している。しかし、上部弾性係止片１７は、その先端がねじ穴３０のねじ山に係止しており、穴塞ぎプラグ１１は、パネル穴２９及びねじ穴３０を塞いだ状態に維持される。このように、比較的簡単な構成の穴塞ぎプラグ１１をパネル穴２９及びねじ穴３０に押込むだけの簡単な作業で、自動車のボデーパネル等に設けられた雌ねじ付きの穴を塞ぐことができる。なお、フランジ１３の突条１８をもって溶接ナット２６のねじの正転方向にフランジ１３を軸心回りに回転すれば、穴塞ぎプラグ１１の固定力を増して、穴塞ぎの水密シールを向上させることができる。   The state in which the hole closing plug 11 having the above configuration closes the panel hole 29 of the body panel 26 as the attached member having the welding nut 27 fixed to the back surface and the screw hole 30 of the welding nut 27 as the female screw member, As shown in FIG. When attaching the hole closing plug 11, the guide 22 at the tip of the column 14 is aligned with the hole 29 of the body panel 26 and the screw hole 30 of the welding nut 27, and the upper surface of the flange 13 is pressed with a finger and the column 14 is pushed in as it is. Rarely, the lower elastic locking piece 15 and the upper elastic locking piece 17 are tilted radially inward. When the flange 13 is pushed in until the lower surface of the flange 13 comes into contact with the body panel 26, the panel hole 29 and the screw hole 30 are closed by the flange 13. In the example of FIG. 12, the body panel 26 is a thin panel, and the welding nut 27 also has a short axial length (height). Therefore, in a state where the flange 13 is in contact with the body panel 26, the lower elastic locking piece 15 passes through the welding nut 27. However, the upper elastic locking piece 17 has its tip locked to the thread of the screw hole 30, and the hole closing plug 11 is maintained in a state where the panel hole 29 and the screw hole 30 are closed. In this way, a hole with a female screw provided in a body panel or the like of an automobile can be closed by a simple operation of simply pushing the hole closing plug 11 having a relatively simple structure into the panel hole 29 and the screw hole 30. . If the flange 13 is rotated about the axis in the forward rotation direction of the screw of the welding nut 26 with the protrusion 18 of the flange 13, the fixing force of the hole closing plug 11 is increased and the water tight seal of the hole closing is improved. Can do.

穴塞ぎプラグ１１を取外すには、フランジ１３を溶接ナット２７のねじの逆転方向に回転させればよい。フランジ１３の回転には、突条１８を指でつまんでフランジ１３を支柱１４の軸心回りに回転させる。回転の続行によって、ねじ山に係合している上部弾性係止片１７の先端がねじ穴３０のねじ山に沿って上方に移動し、この上方への移動によって穴塞ぎプラグ１１がボデーパネル２６から抜き上げられる。下部弾性係止片１５は溶接ナット２７を貫通しているので、穴塞ぎプラグ１１の抜き上げの途中で、下部弾性係止片１５の先端が溶接ナット２７に当接する。下部弾性係止片１５の根元部２３には空間２５が形成されているので、下部弾性係止片１５は、図１３に図示のように、ほぼ１８０度旋回することができ、その下部弾性係止片１５を破損することく、穴塞ぎプラグ１１をボデーパネル２６から取外しできる。従って、取外した穴塞ぎプラグ１１は、そのまま再使用することができる。なお、取外しのとき、突条１８の穴１９を利用して、工具先端を穴１９の挿入して穴塞ぎプラグ１１の引上げを補助したり、紐や針金等を穴１９に通して、紐あるいは針金の引上げによって穴塞ぎプラグ１１の引上げを補助してもよい。   In order to remove the hole closing plug 11, the flange 13 may be rotated in the reverse direction of the screw of the welding nut 27. For rotation of the flange 13, the flange 18 is rotated around the axis of the column 14 by pinching the protrusion 18 with a finger. By continuing the rotation, the tip of the upper elastic locking piece 17 engaged with the screw thread moves upward along the screw thread of the screw hole 30, and the hole closing plug 11 is moved to the body panel 26 by this upward movement. It is pulled out from. Since the lower elastic locking piece 15 penetrates the welding nut 27, the tip of the lower elastic locking piece 15 comes into contact with the welding nut 27 while the hole closing plug 11 is being pulled out. Since the space 25 is formed in the root portion 23 of the lower elastic locking piece 15, the lower elastic locking piece 15 can be swung approximately 180 degrees as shown in FIG. The hole closing plug 11 can be removed from the body panel 26 without damaging the stopper piece 15. Therefore, the removed hole closing plug 11 can be reused as it is. At the time of removal, the hole 19 of the ridge 18 is used to insert the hole 19 into the hole 19 to assist with the lifting of the hole plug 11, or a string or wire is passed through the hole 19 to Pulling up the hole closing plug 11 may be assisted by pulling up the wire.

図１４は、ボデーパネル２６に溶接ナット２７より軸方向長さが長い溶接ナット２７Ａが固着された例を示している。この場合には、穴塞ぎプラグ１１は、その上部弾性係止片１７だけでなく下部弾性係止片１５も、ねじ穴３０Ａのねじ山に係止するので、パネル穴２９Ａ及びねじ穴３０Ａを確実に密閉するように塞ぐ。図１５は、ボデーパネル２６より厚さのあるボデーパネル２６Ａに軸方向長さが長い溶接ナット２７Ａが固着されている例を示している。この場合にも、穴塞ぎプラグ１１は、その上部弾性係止片１７だけでなく下部弾性係止片１５もねじ穴３０Ａのねじ山に係止し、パネル穴２９Ａ及びねじ穴３０Ａを確実に密閉するように塞ぐ。これらの例においても、穴塞ぎプラグ１１の取外しは、フランジ１３を支柱１４の軸心回りに回転させることによって行う。   FIG. 14 shows an example in which a welding nut 27 </ b> A whose axial length is longer than the welding nut 27 is fixed to the body panel 26. In this case, since the hole closing plug 11 not only the upper elastic locking piece 17 but also the lower elastic locking piece 15 is locked to the screw thread of the screw hole 30A, the panel hole 29A and the screw hole 30A are surely secured. Close to seal. FIG. 15 shows an example in which a welding nut 27 </ b> A having a longer axial length is fixed to a body panel 26 </ b> A that is thicker than the body panel 26. Also in this case, the hole closing plug 11 not only locks the upper elastic locking piece 17 but also the lower elastic locking piece 15 to the screw thread of the screw hole 30A, and reliably seals the panel hole 29A and the screw hole 30A. Close like you do. Also in these examples, the hole closing plug 11 is removed by rotating the flange 13 around the axis of the column 14.

上記のように、穴塞ぎプラグ１１は、（１）ナット穴への挿入時の嵌合性、（２）取付作業性、（３）嵌合後の振動等に伴なう脱落防止、（４）水密シール性、（５）取外し容易性、（６）取外し後の再使用性等の、穴塞ぎプラグに必要とされる要件を備えている。   As described above, the hole closing plug 11 includes (1) fitting property when inserted into a nut hole, (2) mounting workability, (3) prevention of falling off due to vibration after fitting, (4 It has the requirements necessary for plugging holes such as :) watertight sealability, (5) ease of removal, (6) reusability after removal.

図１６〜図２２は、本発明の第２実施形態に係る穴塞ぎプラグ１１Ａを示している。図１６〜図２０は、穴塞ぎプラグ１１Ａの構成を示しており、図２１及び図２２は、穴塞ぎプラグ１１Ａがボデーパネル及び溶接ナットの穴を塞いだ状態を示している。第２実施形態に係る穴塞ぎプラグ１１Ａは、第１実施形態に係る穴塞ぎプラグ１１と多くの類似の構成要素を有する。穴塞ぎプラグ１１Ａの構成要素において、穴塞ぎプラグ１１と同じ又は類似の構成要素には対応の符号にＡを付加した符号が付されている。これらの構成要素については、詳細な説明を省略するので、穴塞ぎプラグ１１の対応の構成要素の説明を参照されたい。   16 to 22 show a hole closing plug 11A according to a second embodiment of the present invention. 16 to 20 show the configuration of the hole closing plug 11A, and FIGS. 21 and 22 show the state where the hole closing plug 11A closes the holes of the body panel and the welding nut. The hole closing plug 11A according to the second embodiment has many similar components as the hole closing plug 11 according to the first embodiment. In the constituent elements of the hole closing plug 11A, constituent elements that are the same as or similar to those of the hole closing plug 11 are given reference numerals with A added to the corresponding reference numerals. Since detailed description of these components is omitted, refer to the description of the corresponding components of the hole closing plug 11.

穴塞ぎプラグ１１Ａにおいて、穴塞ぎプラグ１１と違うのは、弾性係止片対が３段に形成されていること、フランジに形成された突条が平面視において細幅で平行な形状のままであってフランジ外縁部に向けて幅広には形成されていないこと、及び、下部弾性係止片の根元部に旋回のための空間が形成されないこと、である。   The hole closing plug 11A is different from the hole closing plug 11 in that the elastic locking piece pairs are formed in three stages, and the protrusions formed on the flange remain narrow and parallel in plan view. That is, it is not formed wide toward the outer edge of the flange, and a space for turning is not formed at the base of the lower elastic locking piece.

穴塞ぎプラグ１１Ａは、熱可塑性合成樹脂で一体成形されている。かかる熱可塑性合成樹脂材料は、比較的硬質の合成樹脂材料であっても、比較的軟質の合成樹脂であってもよい。穴塞ぎプラグ１１Ａは、円盤の吸盤形状のフランジ１３Ａと、フランジ１３Ａの下面中央から垂下する支柱１４Ａと、支柱１４Ａからフランジ１３Ａに向け且つフランジ１３Ａに近づくにつれて支柱１４Ａから離れるように延びる、３対の弾性係止片３４、３５、３７とから成る。フランジ１３Ａは、全体として円盤形状に形成され、下面は、ボデーパネル等の雌ねじ付きの穴を塞いで密閉できるように薄肉の吸盤形状に形成されている。フランジ１３Ａの上面は、指等で押込みが容易にできるように、全体としてほぼ平たい円盤形状に形成されている。また、穴塞ぎプラグ１１Ａを穴から取外す場合、指等で、穴塞ぎプラグ１１Ａを支柱１４Ａの軸心回りに回転できるように、直径方向に細い幅で延びる、上方に突出した突条３８が形成されている。突条３８には、中央の部分に突条３８を貫通する穴１９Ａが形成され、スクリュードライバ等の工具の先端を挿入でき、工具先端で引上げるようにでき、紐や針金等を挿入して、取外し時の引上げに利用することもできる。突条３８は、図１７の平面視において細幅で平行な形状のままに形成されている。突条３８はフランジ１３Ａの全体の強度を増しており、雌ねじ穴の密閉機能が強化される。   The hole closing plug 11A is integrally formed of a thermoplastic synthetic resin. Such a thermoplastic synthetic resin material may be a relatively hard synthetic resin material or a relatively soft synthetic resin. The hole closing plug 11A includes a disc suction cup-shaped flange 13A, a support 14A hanging from the center of the lower surface of the flange 13A, and extending from the support 14A toward the flange 13A and away from the support 14A as it approaches the flange 13A. Elastic locking pieces 34, 35, and 37. The flange 13A is formed in a disk shape as a whole, and the lower surface is formed in a thin suction cup shape so as to be sealed by closing a hole with a female screw such as a body panel. The upper surface of the flange 13A is formed in a substantially flat disk shape as a whole so that it can be easily pushed in with a finger or the like. Further, when removing the hole closing plug 11A from the hole, an upward projecting ridge 38 extending in a narrow width in the diameter direction is formed so that the hole closing plug 11A can be rotated around the axis of the column 14A with a finger or the like. Has been. In the ridge 38, a hole 19A that penetrates the ridge 38 is formed at the center portion, and the tip of a tool such as a screwdriver can be inserted and pulled up by the tool tip. It can also be used for pulling up during removal. The ridge 38 is formed in a narrow and parallel shape in a plan view of FIG. The protrusion 38 increases the overall strength of the flange 13A, and the sealing function of the female screw hole is enhanced.

支柱１４Ａは、フランジ１３Ａに隣接する上部が、円柱部分２１Ａとして形成され、ボデーパネル等の穴に入ってその穴の軸心と支柱１４Ａの軸心とを合わせことができる。円柱部分２１Ａより下方の支柱１４Ａの部分には、３対の、下部弾性係止片３４、中間弾性係止片３５、及び、上部弾性係止片３７が形成されている。支柱１４Ａの円柱部分２１Ａより下方の部分は、支柱の強度を維持する厚さで、各弾性係止片３４、３５、３７が支柱１４Ａ側に撓むことができるように、円柱の両側を削って薄く形成した板状体として形成されている。支柱１４Ａの先端には、挿入穴より十分に小径で穴へ容易に導ける先細のガイド２２Ａが形成されている。   The support 14A has an upper portion adjacent to the flange 13A formed as a cylindrical portion 21A. The support 14A can enter a hole in a body panel or the like and align the axis of the hole with the axis of the support 14A. Three pairs of a lower elastic locking piece 34, an intermediate elastic locking piece 35, and an upper elastic locking piece 37 are formed in the column 14A below the cylindrical portion 21A. The portion below the column portion 21A of the column 14A has a thickness that maintains the strength of the column, and both sides of the column are shaved so that the elastic locking pieces 34, 35, and 37 can bend toward the column 14A. It is formed as a thin plate-like body. A tapered guide 22A that is sufficiently smaller in diameter than the insertion hole and can be easily guided to the hole is formed at the tip of the support post 14A.

３対の弾性係止片３４，３５、３７を設けたことによって、雌ねじが固着されたボデーパネル等の部材の厚さが違っていても、その厚さの違いに対応してねじ穴を塞ぐことができ、ねじ穴への係止個所が増加して、穴塞ぎプラグ１１Ａの固定が強化される。穴塞ぎプラグ１１Ａの挿入力は、人間工学的に作業者に負担が重くならないように３０Ｎ以下に定められ、下部弾性係止片３４、中間弾性係止片３５、上部弾性係止片３７の弾性もそれに合わせて定められる。従って、穴塞ぎプラグ１１Ａの挿入力はそれほど増加せず、作業者への挿入作業の負担は少ない。   By providing three pairs of elastic locking pieces 34, 35, and 37, even if the thickness of a member such as a body panel to which the female screw is fixed is different, the screw hole is closed corresponding to the difference in thickness. As a result, the number of locking points to the screw holes is increased, and the fixing of the hole closing plug 11A is strengthened. The insertion force of the hole closing plug 11A is determined to be 30 N or less so as not to increase the burden on the operator ergonomically, and the elasticity of the lower elastic locking piece 34, the intermediate elastic locking piece 35, and the upper elastic locking piece 37 is determined. Is determined accordingly. Therefore, the insertion force of the hole closing plug 11A does not increase so much, and the burden of the insertion work on the operator is small.

上記構成で成る穴塞ぎプラグ１１Ａが、裏面に雌ねじ部材としての溶接ナット２７が固着されている、被取付部材としてのボデーパネル２６のパネル穴２９及びねじ穴３０を塞いだ状態を、図２１に示す。穴塞ぎプラグ１１Ａの取付けにおいて、フランジ１３Ａの上面が指で押圧されてそのまま支柱１４Ａが押込まれ、下部弾性係止片３４、中間弾性係止片３５、上部弾性係止片３７が半径方向内側に倒される。フランジ１３Ａの下面がボデーパネル２６に接面するまで押込まれると、パネル穴２９及びねじ穴３０が塞がれる。図２１では、ボデーパネル２６が薄いパネルであり、溶接ナット２７も軸方向長さ（高さ）が短い。従って、フランジ１３Ａがボデーパネル２６に接面した状態では、下部弾性係止片３４及び中間弾性係止片３５が溶接ナット２７を貫通している。しかし、上部弾性係止片３７は、その先端がねじ穴３０のねじ山に係止しており、穴塞ぎプラグ１１Ａは、パネル穴２９及びねじ穴３０を塞いだ状態に維持される。穴塞ぎプラグ１１Ａを取外すには、フランジ１３Ａを溶接ナット２７のねじの逆転方向に回転させる。フランジ１３Ａの回転には、突条３８を指でつまんでフランジ１３Ａを支柱１４Ａの軸心回りに回転させ、上部弾性係止片３７の先端がねじ穴３０のねじ山に沿って上方に移動して、穴塞ぎプラグ１１Ａがボデーパネル２６から抜き上げられる。中間弾性係止片３５及び下部弾性係止片３４は溶接ナット２７を貫通しているので、穴塞ぎプラグ１１Ａの抜き上げの途中で、下部弾性係止片１５の先端が溶接ナット２７に当接して、引上げが停止する。そこで、突条３８の穴１９Ａに、工具先端を挿入したり紐や針金を通して、穴塞ぎプラグ１１Ａの引上げを補助する。穴塞ぎプラグ１１Ａが、比較的軟質の合成樹脂で成形されていれば、その引上げにおいて、中間弾性係止片３５及び下部弾性係止片３４はほぼ１８０度旋回することができ、それら中間弾性係止片３５及び下部弾性係止片３４が破損されずに、穴塞ぎプラグ１１Ａが、パネル穴２９及びねじ穴３０から引き抜かれる。従って、穴塞ぎプラグ１１Ａが再使用できる。   FIG. 21 shows a state in which the hole closing plug 11A having the above configuration closes the panel hole 29 and the screw hole 30 of the body panel 26 as the mounted member, with the welding nut 27 as the female screw member fixed to the back surface. Show. In attaching the hole closing plug 11A, the upper surface of the flange 13A is pressed with a finger and the support 14A is pushed in as it is, and the lower elastic locking piece 34, the intermediate elastic locking piece 35, and the upper elastic locking piece 37 are radially inward. Defeated. When the flange 13A is pushed in until the lower surface of the flange 13A comes into contact with the body panel 26, the panel hole 29 and the screw hole 30 are closed. In FIG. 21, the body panel 26 is a thin panel, and the welding nut 27 also has a short axial length (height). Therefore, in a state where the flange 13A is in contact with the body panel 26, the lower elastic locking piece 34 and the intermediate elastic locking piece 35 penetrate the welding nut 27. However, the tip of the upper elastic locking piece 37 is locked to the thread of the screw hole 30, and the hole closing plug 11 </ b> A is maintained in a state where the panel hole 29 and the screw hole 30 are closed. To remove the hole closing plug 11A, the flange 13A is rotated in the reverse direction of the screw of the welding nut 27. The flange 13A is rotated by pinching the protrusion 38 with a finger and rotating the flange 13A around the axis of the support 14A, and the tip of the upper elastic locking piece 37 moves upward along the thread of the screw hole 30. Thus, the hole closing plug 11A is pulled out from the body panel 26. Since the intermediate elastic locking piece 35 and the lower elastic locking piece 34 penetrate the welding nut 27, the tip of the lower elastic locking piece 15 comes into contact with the welding nut 27 while the hole closing plug 11 </ b> A is being pulled out. Pulling stops. Therefore, the tool plug 11A is assisted to be pulled up by inserting the tool tip into the hole 19A of the ridge 38 or through a string or wire. If the hole closing plug 11A is formed of a relatively soft synthetic resin, the intermediate elastic locking piece 35 and the lower elastic locking piece 34 can be turned almost 180 degrees in the pulling up, and the intermediate elastic engagement The hole closing plug 11 </ b> A is pulled out from the panel hole 29 and the screw hole 30 without damaging the stopper piece 35 and the lower elastic locking piece 34. Therefore, the hole closing plug 11A can be reused.

図２２は、厚いボデーパネル２６Ａに長くて大径の溶接ナット２７Ａが固着された例を示している。この場合には、穴塞ぎプラグ１１Ａは、上部弾性係止片３７だけでなく、中間弾性係止片３５及び下部弾性係止片３４も、ねじ穴３０Ａのねじ山に係止するので、パネル穴２９Ａ及びねじ穴３０Ａを確実に密閉するように塞ぐ。この例においても、穴塞ぎプラグ１１Ａの取外しは、フランジ１３Ａの回転によって行う。   FIG. 22 shows an example in which a long and large-diameter welding nut 27A is fixed to a thick body panel 26A. In this case, in the hole closing plug 11A, not only the upper elastic locking piece 37 but also the intermediate elastic locking piece 35 and the lower elastic locking piece 34 are locked to the thread of the screw hole 30A. 29A and the screw hole 30A are closed so as to be surely sealed. Also in this example, the hole closing plug 11A is removed by rotating the flange 13A.

上記のように、穴塞ぎプラグ１１Ａは、（１）ナット穴への挿入時の嵌合性、（２）取付作業性、（３）嵌合後の振動等に伴なう脱落防止、（４）水密シール性、（５）取外し容易性の要件を備えており、比較的軟質の合成樹脂で穴塞ぎプラグ１１Ａを成形することによって、（６）取外し後の再使用性の要件を備えることができる。   As described above, the hole closing plug 11A has (1) fitting property when inserted into a nut hole, (2) mounting workability, (3) prevention of falling off due to vibration after fitting, (4 (5) It has the requirements of watertight sealability, (5) Ease of removal, and by forming the hole plug 11A with a relatively soft synthetic resin, (6) The requirement of reusability after removal can be provided it can.

図２３〜図３０は、本発明の第３実施形態に係る穴塞ぎプラグ１１Ｂを示している。図２３〜図２８は、穴塞ぎプラグ１１Ｂの構成を示しており、図２９及び図３０は、穴塞ぎプラグ１１Ｂがボデーパネル及び溶接ナットの穴を塞いだ状態を示している。第３実施形態に係る穴塞ぎプラグ１１Ｂは、第１実施形態に係る穴塞ぎプラグ１１と多くの類似の構成要素を有する。穴塞ぎプラグ１１Ｂの構成要素において、穴塞ぎプラグ１１と同じ又は類似の構成要素には対応の符号にＢを付加した符号が付されている。これらの構成要素については、詳細な説明を省略するので、穴塞ぎプラグ１１の対応の構成要素の説明を参照されたい。   23 to 30 show a hole closing plug 11B according to a third embodiment of the present invention. 23 to 28 show the configuration of the hole closing plug 11B, and FIGS. 29 and 30 show a state in which the hole closing plug 11B closes the holes of the body panel and the welding nut. The hole closing plug 11B according to the third embodiment has many similar components to the hole closing plug 11 according to the first embodiment. In the constituent elements of the hole closing plug 11B, constituent elements that are the same as or similar to those of the hole closing plug 11 are denoted by reference numerals obtained by adding B to the corresponding reference numerals. Since detailed description of these components is omitted, refer to the description of the corresponding components of the hole closing plug 11.

穴塞ぎプラグ１１Ｂにおいて、穴塞ぎプラグ１１と違うのは、弾性係止片対が３段に形成されていること、フランジ上面には、突条ではなく、十字溝形成部が設けられて、プラスドライバ（クロスヘッドドライバ又はフィリップスヘッドドライバ）で回転できる構成であること、フランジ上面の十字溝形成部がフランジ上面との間に隙間が形成されて、指又はペンチ等の工具先端が係合できるようになっていること、及び、下部弾性係止片の根元部に旋回のための空間が形成されないこと、である。なお、弾性係止片対が３段に形成されていることは、第２実施形態に係る穴塞ぎプラグ１１Ａと同様であり、下部弾性係止片の根元部に旋回のための空間が形成されないことも、第２実施形態に係る穴塞ぎプラグ１１Ａと同様であるので、それらの説明を参照されたい。   The hole closing plug 11B is different from the hole closing plug 11 in that a pair of elastic locking pieces is formed in three steps, and a cross groove forming portion is provided on the upper surface of the flange instead of a ridge. It can be rotated with a screwdriver (cross head driver or Philips head driver), and a gap is formed between the cross groove forming part on the upper surface of the flange and the upper surface of the flange so that the tip of a tool such as a finger or pliers can be engaged. And a space for turning is not formed at the root of the lower elastic locking piece. Note that the elastic locking piece pair is formed in three stages, as in the hole closing plug 11A according to the second embodiment, and a space for turning is not formed at the base portion of the lower elastic locking piece. This is also the same as the hole closing plug 11A according to the second embodiment, so refer to the description thereof.

穴塞ぎプラグ１１Ｂは、熱可塑性合成樹脂で一体成形されている。かかる熱可塑性合成樹脂材料は、比較的硬質の合成樹脂材料であっても、比較的軟質の合成樹脂であってもよい。穴塞ぎプラグ１１Ｂは、円盤の吸盤形状のフランジ１３Ｂと、フランジ１３Ｂの下面中央から垂下する支柱１４Ｂと、支柱１４Ｂからフランジ１３Ｂに向け且つフランジ１３Ｂに近づくにつれて支柱１４Ｂから離れるように延びる、３対の弾性係止片３４Ｂ、３５Ｂ、３７Ｂとから成る。フランジ１３Ｂは、全体として円盤形状に形成され、下面は、ボデーパネル等の雌ねじ付きの穴を塞いで密閉できるように薄肉の吸盤形状に形成されている。   The hole closing plug 11B is integrally formed of a thermoplastic synthetic resin. Such a thermoplastic synthetic resin material may be a relatively hard synthetic resin material or a relatively soft synthetic resin. The hole closing plug 11B includes a disc-shaped suction cup-shaped flange 13B, a support 14B hanging from the center of the lower surface of the flange 13B, and extending from the support 14B toward the flange 13B and away from the support 14B as it approaches the flange 13B. Elastic locking pieces 34B, 35B, and 37B. The flange 13B is formed in a disk shape as a whole, and the lower surface is formed in a thin suction cup shape so as to close and seal a hole with a female screw such as a body panel.

フランジ１３Ｂの上面には、プラスドライバで、フランジ１３Ｂを支柱１４Ｂの軸心回りに回転できるように、板状の十字溝形成部３９が設けられている。十字溝形成部３９には、上面に十字溝４１が形成されている。十字溝形成部３９の下面とフランジ１３Ｂの上面との間には、隙間４２が設けられている。この隙間４２は、指が十字溝形成３９に係合できるように形成され、あるいは、ペンチ等の工具の先端が係合できるように形成されており、穴塞ぎプラグ１１Ｂの取外しのときに、利用できる。板状の十字溝形成部３９は、穴塞ぎプラグ１１Ｂを、ボデーパネルの穴及び溶接ナットのねじ穴を塞ぐときの、指での押込みのとき、押圧する部分として利用される。板状の十字溝形成部３９は、隙間４２を形成するように、細長い連結部４３でフランジ１３Ｂに連結されており、連結部４３はフランジ１３Ｂの全体の強度を増しており、雌ねじ穴の密閉機能が強化される。   A plate-shaped cross groove forming portion 39 is provided on the upper surface of the flange 13B so that the flange 13B can be rotated around the axis of the support column 14B with a Phillips screwdriver. A cross groove 41 is formed on the top surface of the cross groove forming portion 39. A gap 42 is provided between the lower surface of the cross groove forming portion 39 and the upper surface of the flange 13B. The gap 42 is formed so that the finger can engage with the cross groove formation 39, or formed so that the tip of a tool such as pliers can be engaged, and is used when removing the hole closing plug 11B. it can. The plate-shaped cross groove forming portion 39 is used as a portion that presses the hole closing plug 11B when it is pressed with a finger when closing the hole of the body panel and the screw hole of the welding nut. The plate-shaped cross groove forming portion 39 is connected to the flange 13B by an elongated connecting portion 43 so as to form a gap 42. The connecting portion 43 increases the overall strength of the flange 13B, and seals the female screw hole. Function is enhanced.

支柱１４Ｂの下方の部分には、３段になった、下部弾性係止片３４Ｂ、中間弾性係止片３５Ｂ、及び、上部弾性係止片３７Ｂが対になって形成されている。３対の弾性係止片３４Ｂ、３５Ｂ、３７Ｂを設けたことによって、雌ねじが固着されたボデーパネル等の部材の厚さが違っていても、その厚さの違いに対応してねじ穴を塞ぐことができ、ねじ穴への係止個所が増加して、穴塞ぎプラグ１１Ｂの固定が強化される。穴塞ぎプラグ１１Ｂの挿入力は、人間工学的に作業者に負担が重くならないように３０Ｎ以下に定められ、下部弾性係止片３４Ｂ、中間弾性係止片３５Ｂ、上部弾性係止片３７Ｂの弾性もそれに合わせて定められる。従って、穴塞ぎプラグ１１Ｂの挿入力はそれほど増加せず、作業者への挿入作業の負担は少ない。   A lower elastic locking piece 34B, an intermediate elastic locking piece 35B, and an upper elastic locking piece 37B are formed in pairs in the lower part of the support column 14B. By providing the three pairs of elastic locking pieces 34B, 35B, and 37B, even if the thickness of a member such as a body panel to which the female screw is fixed is different, the screw hole is closed corresponding to the difference in thickness. As a result, the number of locking points to the screw holes is increased, and the fixing of the hole closing plug 11B is strengthened. The insertion force of the hole closing plug 11B is determined to be 30 N or less so as not to increase the burden on the worker ergonomically, and the elasticity of the lower elastic locking piece 34B, the intermediate elastic locking piece 35B, and the upper elastic locking piece 37B. Is determined accordingly. Therefore, the insertion force of the hole closing plug 11B does not increase so much, and the burden of the insertion work on the operator is small.

上記構成で成る穴塞ぎプラグ１１Ｂが、裏面に溶接ナット２７が固着されているボデーパネル２６のパネル穴２９及びねじ穴３０を塞いだ状態が、図２９に示されている。穴塞ぎプラグ１１Ｂの取付けにおいて、ボデーパネル２６が薄いパネルであり、溶接ナット２７も軸方向長さ（高さ）が短い。従って、フランジ１３Ｂがボデーパネル２６に接面した状態では、下部弾性係止片３４Ｂ及び中間弾性係止片３５Ｂが溶接ナット２７を貫通している。しかし、上部弾性係止片３７Ｂは、その先端がねじ穴３０のねじ山に係止し、穴塞ぎプラグ１１Ｂは、パネル穴２９及びねじ穴３０を塞いだ状態に維持される。穴塞ぎプラグ１１Ｂを取外すには、十字溝形成部３９の十字溝４１にプラスドライバの先端をあてがって、フランジ１３Ｂを溶接ナット２７のねじの逆転方向に回転させる。この回転によって、上部弾性係止片３７Ｂの先端がねじ穴３０のねじ山に沿って上方に移動して、穴塞ぎプラグ１１Ｂがボデーパネル２６から抜き上げられるが、中間弾性係止片３５Ｂ及び下部弾性係止片３４Ｂは溶接ナット２７を貫通しているので、穴塞ぎプラグ１１Ｂの抜き上げの途中で、下部弾性係止片１５Ｂの先端が溶接ナット２７に当接して引上げが停止する。そこで、十字溝形成部３９とフランジ１３Ｂとの間の隙間４２に、指又はペンチの先端を差し入れて、穴塞ぎプラグ１１Ｂの引上げを補助する。穴塞ぎプラグ１１Ｂが、比較的軟質の合成樹脂で成形されていれば、その引上げにおいて、中間弾性係止片３５Ｂ及び下部弾性係止片３４Ｂはほぼ１８０度旋回することができ、弾性係止片の破損なしに、穴塞ぎプラグ１１Ｂが、パネル穴２９及びねじ穴３０から引き抜かれる。従って、穴塞ぎプラグ１１Ｂが再使用できる。   FIG. 29 shows a state in which the hole closing plug 11B configured as described above closes the panel hole 29 and the screw hole 30 of the body panel 26 in which the welding nut 27 is fixed to the back surface. In attaching the hole closing plug 11B, the body panel 26 is a thin panel, and the welding nut 27 also has a short axial length (height). Therefore, in a state where the flange 13B is in contact with the body panel 26, the lower elastic locking piece 34B and the intermediate elastic locking piece 35B penetrate the welding nut 27. However, the top end of the upper elastic locking piece 37B is locked to the thread of the screw hole 30, and the hole closing plug 11B is maintained in a state where the panel hole 29 and the screw hole 30 are closed. To remove the hole closing plug 11B, the tip of a Phillips screwdriver is applied to the cross groove 41 of the cross groove forming portion 39, and the flange 13B is rotated in the reverse direction of the screw of the welding nut 27. By this rotation, the tip of the upper elastic locking piece 37B moves upward along the thread of the screw hole 30, and the hole closing plug 11B is pulled out from the body panel 26. Since the elastic locking piece 34B penetrates the welding nut 27, the tip of the lower elastic locking piece 15B comes into contact with the welding nut 27 in the middle of pulling out the hole closing plug 11B, and the lifting is stopped. Therefore, the tip of a finger or pliers is inserted into the gap 42 between the cross groove forming portion 39 and the flange 13B to assist the pulling up of the hole closing plug 11B. If the hole closing plug 11B is formed of a relatively soft synthetic resin, the intermediate elastic locking piece 35B and the lower elastic locking piece 34B can be swung almost 180 degrees in the pulling up, and the elastic locking piece The hole closing plug 11B is pulled out from the panel hole 29 and the screw hole 30 without damage. Therefore, the hole closing plug 11B can be reused.

図３０は、厚いボデーパネル２６Ａに長くて大径の溶接ナット２７Ａが固着された例を示している。この場合には、穴塞ぎプラグ１１Ｂは、上部弾性係止片３７Ｂだけでなく、中間弾性係止片３５Ｂ及び下部弾性係止片３４Ｂも、ねじ穴３０Ａのねじ山に係止しており、パネル穴２９Ａ及びねじ穴３０Ａを確実に密閉するように塞ぐ。この例においても、穴塞ぎプラグ１１Ａの取外しは、フランジ１３Ａの回転によって行う。   FIG. 30 shows an example in which a long and large-diameter welding nut 27A is fixed to a thick body panel 26A. In this case, in the hole closing plug 11B, not only the upper elastic locking piece 37B but also the intermediate elastic locking piece 35B and the lower elastic locking piece 34B are locked to the thread of the screw hole 30A. The hole 29A and the screw hole 30A are closed so as to be surely sealed. Also in this example, the hole closing plug 11A is removed by rotating the flange 13A.

上記のように、穴塞ぎプラグ１１Ｂは、（１）ナット穴への挿入時の嵌合性、（２）取付作業性、（３）嵌合後の振動等に伴なう脱落防止、（４）水密シール性、（５）取外し容易性の要件を備えており、比較的軟質の合成樹脂で穴塞ぎプラグ１１Ａを成形することによって、（６）取外し後の再使用性の要件を備えている。   As described above, the hole closing plug 11B has (1) fitting property when inserted into the nut hole, (2) mounting workability, (3) prevention of falling off due to vibration after fitting, (4 It has requirements for watertight sealability, (5) ease of removal, and by molding the hole plug 11A with a relatively soft synthetic resin, (6) requirements for reusability after removal. .
