Description

本発明は、樹脂部材を金属部材にボルトとナットにより締結固定するための樹脂部材の締結構造に関する。   The present invention relates to a resin member fastening structure for fastening a resin member to a metal member with a bolt and a nut.

下記特許文献１には、合成樹脂製部材のフランジ部にインサート成形によりカラーを嵌合固着させると共に、ボルトの頭部の裏面に環状平面部を有する環状凸部を設け、ボルトを締め付けることで、合成樹脂製部材と金属製のシリンダブロックとを固定した構造が開示されている。この構造では、ボルトを締め付けたときに、ボルトの頭部の環状凸部がフランジ部上面を弾性的に凹ませて押圧し、カラーも押圧することで、締付力が合成樹脂製部材に大きな負荷を与えることを軽減する。   In the following Patent Document 1, the collar is fitted and fixed to the flange portion of the synthetic resin member by insert molding, and an annular convex portion having an annular flat portion is provided on the back surface of the bolt head, and the bolt is tightened. A structure in which a synthetic resin member and a metal cylinder block are fixed is disclosed. In this structure, when the bolt is tightened, the annular convex portion of the bolt head elastically dents and presses the upper surface of the flange portion, and also presses the collar, so that the tightening force is large on the synthetic resin member. Reduce the load.

実開平５−１２７１２号公報Japanese Utility Model Publication No. 5-12712

しかしながら、上記特許文献１に記載の構造では、ボルトの頭部の裏面に環状平面部を有する環状凸部が設けられているため、ボルトを締め付けたときに、先端の環状平面部が樹脂部材に鋭く食い込まず、樹脂部材の回転やズレが発生する可能性がある。   However, in the structure described in Patent Document 1, an annular convex portion having an annular flat surface portion is provided on the back surface of the head of the bolt, so that when the bolt is tightened, the annular flat surface portion at the tip becomes the resin member. There is a possibility that the resin member may not rotate sharply and the resin member may rotate or shift.

また、合成樹脂製部材のフランジ部にインサート成形によりカラーを嵌合固着させるため、例えば、車両用樹脂ドアなどのような大型の成形品に対しては、多数のカラーを嵌合固着しなければならず、コストが上昇する。   Further, since the collar is fitted and fixed to the flange portion of the synthetic resin member by insert molding, for example, a large number of collars such as a resin door for a vehicle must be fitted and fixed. The cost increases.

本発明は上記事実を考慮し、樹脂部材の回転及びズレを抑制することができる樹脂部材の締結構造を得ることが目的である。   In view of the above facts, an object of the present invention is to obtain a resin member fastening structure capable of suppressing rotation and displacement of the resin member.

請求項２の発明は、請求項１に記載の樹脂部材の締結構造において、前記突起は、前記カラーの鍔部の最外周に設けられている。   According to a second aspect of the present invention, in the resin member fastening structure according to the first aspect, the protrusion is provided on the outermost periphery of the collar portion of the collar.

請求項１記載の本発明によれば、貫通孔を備えた板状の金属部材に、孔部を備えた板状の樹脂部材が重ね合わされ、樹脂部材の孔部に金属製のカラーの筒部が挿入されている。ボルトが一方の側からカラーのボルト貫通孔及び金属部材の貫通孔に貫通され、他方の側からナットを螺合させることで、ボルトとナットにより金属部材と樹脂部材とが締結固定される。その際、カラーの筒部の一端に形成された鍔部の樹脂部材側の面には、樹脂部材の側に突出するスパイク状の突起が設けられており、ボルトとナットによる締結時に、突起が樹脂部材に食い込む。さらに、カラーの筒部の外径が軸方向に沿って同じであり、かつ、樹脂部材の孔部の内径が軸方向に沿って同じであり、カラーの筒部の外壁面と樹脂部材の孔部の内壁面との間の隙よりも、ボルトの軸部とカラーの筒部の内壁面との間の隙が小さい。これにより、樹脂部材の回転及びズレが抑制される。 According to this invention of Claim 1, the plate-shaped resin member provided with the hole is overlapped on the plate-shaped metal member provided with the through hole, and the cylindrical portion of the metal collar is formed in the hole of the resin member.

図１には、一実施形態の樹脂部材の締結構造１０が断面図にて示されている。また、図２（Ａ）、（Ｂ）には、図１に示す樹脂部材の締結構造１０に用いられるカラー１６が斜視図及び断面図にて示されている。図１に示されるように、樹脂部材の締結構造１０は、金属パネルからなる板状の金属部材１２と、この金属部材１２の上に重ね合わされた板状の樹脂部材１４と、を備えている。   FIG. 1 is a cross-sectional view of a resin member fastening structure 10 according to an embodiment. 2A and 2B, a collar 16 used in the resin member fastening structure 10 shown in FIG. 1 is shown in a perspective view and a sectional view. As shown in FIG. 1, the resin member fastening structure 10 includes a plate-like metal member 12 made of a metal panel, and a plate-like resin member 14 superimposed on the metal member 12. .

金属部材１２には、平面視にて円形の貫通孔１２Ａが形成されており、貫通孔１２Ａにボルト２０の軸部２０Ａが貫通される。樹脂部材１４には、平面視にて円形の孔部１４Ａが形成されている。   The metal member 12 is formed with a circular through hole 12A in plan view, and the shaft portion 20A of the bolt 20 is passed through the through hole 12A. The resin member 14 is formed with a circular hole portion 14A in plan view.

また、樹脂部材の締結構造１０は、樹脂部材１４の孔部１４Ａに挿入される筒部１６Ａを有する金属製のカラー１６を備えている。カラー１６の筒部１６Ａには、軸方向に沿って平面視にて円形のボルト貫通孔１８が形成されている。さらに、樹脂部材の締結構造１０は、カラー１６のボルト貫通孔１８及び金属部材１２の貫通孔１２Ａに樹脂部材１４の側（一方の側）から軸部２０Ａが挿通されるボルト２０と、金属部材１２の側（他方の側）からボルト２０の軸部２０Ａに形成されたねじ部に螺合されるナット２２と、を備えている。ボルト２０の軸部２０Ａの軸方向の一端には、平面視にて六角形状の頭部２０Ｂが設けられている。   The resin member fastening structure 10 includes a metal collar 16 having a cylindrical portion 16 </ b> A inserted into the hole portion 14 </ b> A of the resin member 14. A circular bolt through-hole 18 is formed in the cylindrical portion 16A of the collar 16 in plan view along the axial direction. Further, the resin member fastening structure 10 includes a bolt 20 through which the shaft portion 20A is inserted from the resin member 14 side (one side) into the bolt through hole 18 of the collar 16 and the through hole 12A of the metal member 12, and the metal member. And a nut 22 screwed into a threaded portion formed on the shaft portion 20A of the bolt 20 from the 12 side (the other side). A hexagonal head 20B is provided at one axial end of the shaft portion 20A of the bolt 20 in plan view.

図１及び図２（Ａ）、（Ｂ）に示されるように、カラー１６は、ボルト貫通孔１８が形成された円筒状の筒部１６Ａと、筒部１６Ａの軸方向の一端に形成された鍔部１６Ｂと、を備えている。カラー１６は、鍔部１６Ｂが樹脂部材１４の上面（表面）側に配置された状態で、筒部１６Ａが樹脂部材１４の孔部１４Ａに挿入されている。   As shown in FIG. 1 and FIGS. 2A and 2B, the collar 16 is formed at a cylindrical tube portion 16A in which a bolt through hole 18 is formed, and at one end of the tube portion 16A in the axial direction. And a collar portion 16B. In the collar 16, the cylinder portion 16 </ b> A is inserted into the hole portion 14 </ b> A of the resin member 14 in a state where the flange portion 16 </ b> B is disposed on the upper surface (front surface) side of the resin member 14.

鍔部１６Ｂは、平面視にて円形状に形成されており、鍔部１６Ｂの裏面（筒部１６Ａの側を向いた面）２６の外周縁（最外周）には、筒部１６Ａに沿って突出するスパイク状の突起２８が形成されている。すなわち、カラー１６の筒部１６Ａが樹脂部材１４の孔部１４Ａに挿入された状態では、鍔部１６Ｂの突起２８は樹脂部材１４の上面(表面）側に向かって突出している（図１参照）。突起２８は、先端が略尖形で鋭利な形状とされており、断面視にて突起２８の先端の角部は鋭角となっている。なお、本実施形態では、突起２８の先端の角部は、製造上の金型形状により、角部が若干切り欠かれた形状とされている。突起２８の先端は、ボルト２０の軸部２０Ａにナット２２を螺合させて樹脂部材１４と金属部材１２とを締結固定したときに、樹脂部材１４の上面（表面）に食い込みが可能とされている。突起２８は、鍔部１６Ｂの裏面２６の外周縁に周方向に沿って連続して形成されている。   The flange portion 16B is formed in a circular shape in plan view, and the outer peripheral edge (outermost periphery) of the back surface (the surface facing the cylinder portion 16A) 26 of the flange portion 16B is along the cylinder portion 16A. A protruding spike-like projection 28 is formed. That is, in a state where the cylindrical portion 16A of the collar 16 is inserted into the hole portion 14A of the resin member 14, the protrusion 28 of the flange portion 16B protrudes toward the upper surface (front surface) side of the resin member 14 (see FIG. 1). . The protrusion 28 has a sharp tip with a sharp tip, and the corner of the tip of the protrusion 28 has an acute angle in a cross-sectional view. In the present embodiment, the corner portion at the tip of the projection 28 has a shape in which the corner portion is slightly cut away due to the shape of the mold for manufacturing. When the nut 22 is screwed into the shaft portion 20A of the bolt 20 and the resin member 14 and the metal member 12 are fastened and fixed, the tip of the protrusion 28 can be bite into the upper surface (surface) of the resin member 14. Yes. The protrusion 28 is continuously formed along the circumferential direction on the outer peripheral edge of the back surface 26 of the flange portion 16B.

次に、本実施形態の作用並びに効果について説明する。   Next, the operation and effect of this embodiment will be described.

図１に示されるように、カラー１６の鍔部１６Ｂに突起２８を形成することで、ボルト２０の軸部２０Ａにナット２２を螺合させて樹脂部材１４と金属部材１２とを締結固定したときに、この突起２８がボルト２０とナット２２の締結時の軸力で樹脂部材１４の表面に食い込む。これにより、樹脂部材１４の厚み方向にバラツキが生じても（例えば、樹脂部材１４の孔部１４Ａの周囲で厚み方向にバラツキが生じても）、突起２８が締結時の軸力で樹脂部材１４に食い込むことで、樹脂部材１４とカラー１６とのズレを防止又は抑制することができる。言い換えると、突起２８の樹脂部材１４への食い込み深さで、樹脂部材１４の厚み方向のバラツキを吸収し、樹脂部材１４とカラー１６とのズレを防止又は抑制することができる。   As shown in FIG. 1, when the protrusions 28 are formed on the collar portion 16 </ b> B of the collar 16, the nut 22 is screwed onto the shaft portion 20 </ b> A of the bolt 20 to fasten and fix the resin member 14 and the metal member 12. In addition, the protrusion 28 bites into the surface of the resin member 14 by the axial force when the bolt 20 and the nut 22 are fastened. Thereby, even if variation occurs in the thickness direction of the resin member 14 (for example, variation occurs in the thickness direction around the hole 14A of the resin member 14), the resin member 14 is caused by the axial force when the projection 28 is fastened. Deviation between the resin member 14 and the collar 16 can be prevented or suppressed. In other words, the depth of penetration of the protrusions 28 into the resin member 14 can absorb the variation in the thickness direction of the resin member 14 and prevent or suppress the deviation between the resin member 14 and the collar 16.

本実施形態では、カラー１６の鍔部１６Ｂの外周縁（最外周）に突起２８が設けられており、金属加工（本例では鍛造）により突起２８を形成するときに、材料の流れが良くなる。これにより、図２（Ｂ）に示されるように、より鋭利な突起２８の形状、すなわち、鍔部１６Ｂの裏面２６からの高さＨが高く、カラー１６の半径方向における突起２８の幅Ｗが細い（小さい）形状を形成することが可能である。   In this embodiment, the protrusion 28 is provided on the outer peripheral edge (outermost periphery) of the collar portion 16B of the collar 16, and the material flow is improved when the protrusion 28 is formed by metal processing (forging in this example). . As a result, as shown in FIG. 2B, the shape of the sharper projection 28, that is, the height H from the back surface 26 of the collar portion 16B is high, and the width W of the projection 28 in the radial direction of the collar 16 is increased. It is possible to form a thin (small) shape.

鍔部１６Ｂの裏面２６からの突起２８の高さＨが高いことで、樹脂部材１４の厚みのバラツキにより確実に対応することができる。言い換えると、同じ厚みバラツキの樹脂部材１４であれば、突起２８がより深く食い込むようにすることができ、樹脂部材１４の固定力がより強くなる。また、カラー１６の半径方向における突起２８の幅Ｗが細い（小さい）ことにより、突起２８を樹脂部材１４に食い込ませるための軸力が小さくてすむ。図３（Ａ）に示されるように、カラー１６の半径方向における突起２８の幅Ｗが細いことで、低い軸力で突起２８が樹脂部材１４に食い込む。   Since the height H of the protrusion 28 from the back surface 26 of the flange portion 16B is high, it is possible to reliably cope with the variation in the thickness of the resin member 14. In other words, if the resin member 14 has the same thickness variation, the protrusions 28 can be deeper and the fixing force of the resin member 14 becomes stronger. Further, since the width W of the projection 28 in the radial direction of the collar 16 is thin (small), the axial force for causing the projection 28 to bite into the resin member 14 can be reduced. As shown in FIG. 3A, the protrusion 28 bites into the resin member 14 with a low axial force because the width W of the protrusion 28 in the radial direction of the collar 16 is narrow.

突起２８を食い込ませるための軸力は、樹脂部材１４のクリープ変形により、いずれ低下するため、部材の固定のためには使われない。つまり、初期の軸力は、「部材を固定するための軸力」と「樹脂部材１４に突起２８を食い込ませる軸力」であり、「部材を固定するための軸力」は、ボルト２０とカラー１６と金属部材１２とナット２２による固定であり、各部品が金属であるため、軸力がほとんど低下しない。これに対し、「樹脂部材１４に突起２８を食い込ませる軸力」は、樹脂部材１４のクリープ変形により低下するため、極力小さくし、部材の固定には使わないようにしている。   Since the axial force for causing the protrusions 28 to bite is eventually reduced due to creep deformation of the resin member 14, it is not used for fixing the member. That is, the initial axial force is “an axial force for fixing the member” and “an axial force for causing the protrusion 28 to bite into the resin member 14”, and “an axial force for fixing the member” Since it is fixed by the collar 16, the metal member 12, and the nut 22, and each component is metal, the axial force hardly decreases. On the other hand, “the axial force that causes the protrusion 28 to bite into the resin member 14” decreases due to creep deformation of the resin member 14, and thus is made as small as possible so that it is not used for fixing the member.

ここで、クリープ変形とは、樹脂部材に荷重を加え続けると、長時間連続的に変形が続く現象をいう。例えば、ボルトの頭部で樹脂部材を締め付けると、クリープ現象によって時間の経過によりボルト締めの圧力が低下する。   Here, creep deformation refers to a phenomenon in which deformation continues continuously for a long time when a load is continuously applied to the resin member. For example, when the resin member is tightened with the head portion of the bolt, the bolt tightening pressure decreases with time due to the creep phenomenon.

図３（Ａ）に示されるように、カラー１６の半径方向における突起２８の幅Ｗが細い（小さい）ことで、低い軸力で突起２８が樹脂部材１４に食い込むが、カラーの半径方向における突起の幅Ｗが大きくなると、突起が樹脂部材１４に食い込みにくくなる。   As shown in FIG. 3A, the width 28 of the protrusion 28 in the radial direction of the collar 16 is thin (small), so that the protrusion 28 bites into the resin member 14 with a low axial force. As the width W increases, the protrusions hardly bite into the resin member 14.

図３（Ｂ）に示す第１比較例のカラー１１６では、カラー１１６の鍔部１６Ｂの半径方向における突起１１８の幅Ｗ２が大きく、突起１１８の先端に平面部１１９が形成されている。このカラー１１６では、締結時に突起１１８の平面部１１９が樹脂部材１４の表面に当たり、突起１１８が樹脂部材１４に食い込みにくい。このため、樹脂部材１４が回転し、カラー１１６の軸方向と直交する方向（矢印Ｄに示すせん断方向）に樹脂部材１４がずれる可能性がある。   In the collar 116 of the first comparative example shown in FIG. 3B, the width W2 of the projection 118 in the radial direction of the collar portion 16B of the collar 116 is large, and the flat portion 119 is formed at the tip of the projection 118. In the collar 116, the flat portion 119 of the protrusion 118 hits the surface of the resin member 14 during fastening, and the protrusion 118 is unlikely to bite into the resin member 14. For this reason, the resin member 14 may rotate, and the resin member 14 may be displaced in a direction orthogonal to the axial direction of the collar 116 (shear direction indicated by arrow D).

これに対して、本実施形態の樹脂部材の締結構造１０では、図１に示されるように、カラー１６の突起２８が樹脂部材１４に食い込むことで、樹脂部材１４の回転や、カラー１６に対する樹脂部材１４のせん断方向のズレを防止又は抑制することができる。   In contrast, in the resin member fastening structure 10 of the present embodiment, as shown in FIG. 1, the protrusions 28 of the collar 16 bite into the resin member 14, so that the resin member 14 rotates and the resin with respect to the collar 16. Deviation in the shear direction of the member 14 can be prevented or suppressed.

また、図４に示されるように、カラー１６の鍔部１６Ｂの外周縁（最外周）に突起２８が形成されていることで、鍔部１６Ｂの半径方向の途中に突起を設けた場合と比較して、カラー１６の鍔部１６Ｂの外径Ａを小さくすることができる。これにより、カラー１６の鍔部１６Ｂがボルト２０の頭部２０Ｂから半径方向外側に突出する量が少なくなり、見栄えが良好となる。   Also, as shown in FIG. 4, the projections 28 are formed on the outer peripheral edge (outermost periphery) of the collar portion 16B of the collar 16, so that the projection is provided in the middle of the collar portion 16B in the radial direction. Thus, the outer diameter A of the collar portion 16B of the collar 16 can be reduced. Thereby, the amount that the collar portion 16B of the collar 16 protrudes radially outward from the head portion 20B of the bolt 20 is reduced, and the appearance is improved.

また、突起２８の樹脂部材１４への食い込みにより、カラー１６に対する樹脂部材１４のせん断方向のズレを防止又は抑制することができる。これにより、図４に示されるように、カラー１６の筒部１６Ａの外壁面と樹脂部材１４の孔部１４Ａの内壁面との間に隙Ｓ１を与え、筒部１６Ａの外径と孔部１４Ａの内径とのバラツキを吸収させることができる。このため、ボルト２０の軸部２０Ａと、カラー１６の筒部１６Ａの内壁面との間の隙Ｂを最小とすることができる。これにより、ボルト２０とカラー１６の中心軸に大きなズレがなく、見栄えが良好である。   Further, the protrusion 28 bites into the resin member 14, so that the displacement of the resin member 14 with respect to the collar 16 in the shear direction can be prevented or suppressed. As a result, as shown in FIG. 4, a gap S1 is provided between the outer wall surface of the cylindrical portion 16A of the collar 16 and the inner wall surface of the hole portion 14A of the resin member 14, and the outer diameter of the cylindrical portion 16A and the hole portion 14A. Variations with the inner diameter can be absorbed. For this reason, the gap B between the shaft portion 20A of the bolt 20 and the inner wall surface of the cylindrical portion 16A of the collar 16 can be minimized. Thereby, there is no big shift in the central axis of the bolt 20 and the collar 16, and the appearance is good.

なお、本実施形態では、突起２８は、鍔部１６Ｂの裏面２６の周縁部に周方向に沿って連続して形成されているが、これに限定されず、周方向の一部に不連続な部分があってもよい。   In the present embodiment, the protrusion 28 is continuously formed along the circumferential direction on the peripheral portion of the back surface 26 of the flange portion 16B. However, the present invention is not limited to this, and the protrusion 28 is discontinuous in a part of the circumferential direction. There may be parts.

また、本実施形態では、ナット２２が用いられているが、ナット２２に代えて、金属部材１２に溶接等により固着されるウェルドナットを用いてもよい。   In the present embodiment, the nut 22 is used. However, a weld nut fixed to the metal member 12 by welding or the like may be used instead of the nut 22.

The wall portion (resin member) 45 of the resin inner panel 44 and the wall portion (metal member) 46A of the metal reinforcement 46 are fastened and fixed by the resin member fastening structure 10 of the present embodiment.

樹脂部材の締結構造１０には、カラー１６とボルト２０とウェルドナット５０とが用いられている。ウェルドナット５０は、リインフォース４６のインナパネル４４と反対側の面に溶接等により固着されている。ボルト２０をウェルドナット５０に締結することで、カラー１６の突起２８がインナパネル４４の壁部４５に食い込む。これにより、インナパネル４４の壁部４５のせん断方向のズレを防止又は抑制することができる。   A collar 16, a bolt 20, and a weld nut 50 are used in the resin member fastening structure 10. The weld nut 50 is fixed to the surface of the reinforcement 46 opposite to the inner panel 44 by welding or the like. By fastening the bolt 20 to the weld nut 50, the projection 28 of the collar 16 bites into the wall portion 45 of the inner panel 44. Thereby, the shift | offset | difference of the shear direction of the wall part 45 of the inner panel 44 can be prevented or suppressed.

なお、リインフォース４６の車両幅方向内側の端部４６Ｂは、インナパネル４４の凹状部４４Ａの車両幅方向内側の壁部と、締結具５６を用いて締結固定されている。   The end 46 </ b> B on the inner side in the vehicle width direction of the reinforcement 46 is fastened and fixed using a fastener 56 and a wall portion on the inner side in the vehicle width direction of the concave portion 44 </ b> A of the inner panel 44.

A deck side trim 68 is disposed inside the vehicle body 60 of the vehicle.

このようなバックドア４０では、樹脂製のインナパネル４４の壁部４５と金属製のリインフォース４６の壁部４６Ａが、カラー１６とボルト２０とウェルドナット５０を用いて締結固定されており、カラー１６の突起２８がインナパネル４４の壁部４５に食い込んでいる。これにより、カラー１６に対するインナパネル４４の壁部４５のせん断方向のズレを防止又は抑制することができる。   In such a back door 40, the wall portion 45 of the resin inner panel 44 and the wall portion 46A of the metal reinforcement 46 are fastened and fixed using the collar 16, the bolt 20, and the weld nut 50. The protrusion 28 bites into the wall 45 of the inner panel 44. Thereby, the shift | offset | difference of the shear direction of the wall part 45 of the inner panel 44 with respect to the color | collar 16 can be prevented or suppressed.

図６には、第２比較例の樹脂部材の締結構造１２０が示されている。   FIG. 6 shows a fastening structure 120 of the resin member of the second comparative example.

図６に示されるように、この樹脂部材の締結構造１２０では、金属製のカラー１２２は、樹脂部材１４の孔部１４Ａに挿入される筒部１２２Ａと、筒部１２２Ａに形成されたボルト貫通孔１２４と、筒部１２２Ａの一端に形成された鍔部１２２Ｂとを備えている。カラー１２２の筒部１２２Ａが樹脂部材１４の孔部１４Ａに挿入された状態で、鍔部１２２Ｂの裏面が樹脂部材１４の表面に接触している。このカラー１２２は、鍔部１２２Ｂの裏面は平面状とされており、鍔部１２２Ｂの外周縁に突起は設けられていない。   As shown in FIG. 6, in this resin member fastening structure 120, the metal collar 122 includes a cylindrical portion 122 </ b> A inserted into the hole portion 14 </ b> A of the resin member 14, and a bolt through hole formed in the cylindrical portion 122 </ b> A. 124 and a flange 122B formed at one end of the cylindrical portion 122A. With the cylindrical portion 122A of the collar 122 inserted into the hole portion 14A of the resin member 14, the back surface of the flange portion 122B is in contact with the surface of the resin member 14. The collar 122 has a flat back surface of the collar portion 122B, and no protrusion is provided on the outer peripheral edge of the collar portion 122B.

このカラー１２２は、筒部１２２Ａの外壁面と樹脂部材１４の孔部１４Ａの内壁面との間にほとんど隙が設けられておらず、カラー１２２のせん断方向のズレを樹脂部材１４の孔部１４Ａの内壁面で抑止しようとしている（この場合でも、樹脂部材１４の孔部１４Ａのバラツキ分の隙やガタが残る）。このため、樹脂部材１４の孔部１４Ａとの間のバラツキを吸収するために、ボルト２０の軸部２０Ａとカラー１２２のボルト貫通孔１２４の内壁面との間の隙Ｓ２を大きくする必要がある。これによって、図６中のＢ、Ｃに示されるように、ボルト２０とカラー１２２の偏心が起き、見栄えが悪化する。   The collar 122 has almost no gap between the outer wall surface of the cylindrical portion 122A and the inner wall surface of the hole portion 14A of the resin member 14, and the collar 122 is displaced in the shearing direction in the hole portion 14A of the resin member 14. (In this case, there is still a gap or backlash corresponding to the variation of the hole 14A of the resin member 14). For this reason, in order to absorb the variation between the hole portion 14A of the resin member 14, it is necessary to increase the gap S2 between the shaft portion 20A of the bolt 20 and the inner wall surface of the bolt through hole 124 of the collar 122. . Thereby, as shown by B and C in FIG. 6, the eccentricity of the bolt 20 and the collar 122 occurs, and the appearance is deteriorated.

これに対して、本実施形態の樹脂部材の締結構造１０では、図４に示されるように、カラー１６の筒部１６Ａの外壁面と樹脂部材１４の孔部１４Ａの内壁面との間に隙Ｓ１を与え、ボルト２０の軸部２０Ａとカラー１６の筒部１６Ａの内壁面との間の隙Ｂを最小とすることで、ボルト２０とカラー１６の中心軸に大きなズレはなく、見栄えが良好である。   On the other hand, in the resin member fastening structure 10 of the present embodiment, as shown in FIG. 4, there is a gap between the outer wall surface of the cylindrical portion 16 </ b> A of the collar 16 and the inner wall surface of the hole portion 14 </ b> A of the resin member 14. By giving S1 and minimizing the gap B between the shaft portion 20A of the bolt 20 and the inner wall surface of the cylindrical portion 16A of the collar 16, there is no large displacement between the central axes of the bolt 20 and the collar 16, and the appearance is good. It is.

図７（Ａ）及び図８には、第３比較例の樹脂部材の締結構造１３０が示されている。   7A and 8 show a resin member fastening structure 130 of a third comparative example.

図７（Ａ）及び図８に示されるように、この樹脂部材の締結構造１３０では、樹脂部材１４と金属部材１２とを締結固定するために段付ボルト１３２が用いられている。図７（Ｂ）に示されるように、段付ボルト１３２は、ねじ部が形成された軸部１３２Ａと、軸部１３２Ａの先端と反対側に軸部１３２Ａの外径より外径が大きく形成された円柱状の段部１３２Ｂと、段部１３２Ｂの軸部１３２Ａと反対側に隣接して形成されたフランジ部１３２Ｃと、フランジ部１３２Ｃの段部１３２Ｂと反対側に隣接して形成された頭部１３２Ｄと、を備えている。   As shown in FIGS. 7A and 8, in the resin member fastening structure 130, stepped bolts 132 are used to fasten and fix the resin member 14 and the metal member 12. As shown in FIG. 7B, the stepped bolt 132 has a shaft portion 132A in which a thread portion is formed, and an outer diameter that is larger than the outer diameter of the shaft portion 132A on the side opposite to the tip of the shaft portion 132A. A cylindrical step 132B, a flange 132C formed adjacent to the opposite side of the shaft 132A of the step 132B, and a head formed adjacent to the opposite side of the step 132B of the flange 132C. 132D.

図７（Ａ）に示されるように、この樹脂部材の締結構造１３０では、金属部材１２の下面の貫通孔１２Ａの縁部にウェルドナット１３６が溶接等により接合されている。そして、樹脂部材１４の側から孔部１４Ａに段付ボルト１３２の軸部１３２Ａを挿入し、軸部１３２Ａを金属部材１２の貫通孔１２Ａを貫通させてウェルドナット１３６に螺合させる。段付ボルト１３２を締め付けることで、樹脂部材１４の孔部１４Ａに段付ボルト１３２の段部１３２Ｂが挿入され、段部１３２Ｂの下面１３３が金属部材１２に当接される。この状態で、段付ボルト１３２のフランジ部１３２Ｃが樹脂部材１４の表面に接触し、金属部材１２と樹脂部材１４とが固定される。   As shown in FIG. 7A, in this resin member fastening structure 130, a weld nut 136 is joined to the edge of the through hole 12A on the lower surface of the metal member 12 by welding or the like. Then, the shaft portion 132A of the stepped bolt 132 is inserted into the hole portion 14A from the resin member 14 side, and the shaft portion 132A is threaded into the weld nut 136 through the through hole 12A of the metal member 12. By tightening the stepped bolt 132, the stepped portion 132B of the stepped bolt 132 is inserted into the hole 14A of the resin member 14, and the lower surface 133 of the stepped portion 132B is brought into contact with the metal member 12. In this state, the flange portion 132C of the stepped bolt 132 comes into contact with the surface of the resin member 14, and the metal member 12 and the resin member 14 are fixed.

図９には、第４比較例の樹脂部材の締結構造１５０が示されている。   FIG. 9 shows a fastening structure 150 of the resin member of the fourth comparative example.

図９に示されるように、この樹脂部材の締結構造１５０では、樹脂部材１４と金属部材１２とを締結固定するためにフランジボルト１５２と金属製のカラー１５４とが用いられている。フランジボルト１５２は、ねじ部が形成された軸部１５２Ａと、軸部１５２Ａの先端と反対側に軸部１５２Ａの外径より外径が大きく形成されたフランジ部１５２Ｂと、フランジ部１５２Ｂの軸部１５２Ａと反対側に隣接して形成された頭部１５２Ｃと、を備えている。カラー１５４は、樹脂部材１４の厚みとほぼ同じ長さの円筒体とされている。   As shown in FIG. 9, in the resin member fastening structure 150, a flange bolt 152 and a metal collar 154 are used to fasten and fix the resin member 14 and the metal member 12. The flange bolt 152 includes a shaft portion 152A having a threaded portion, a flange portion 152B having an outer diameter larger than the outer diameter of the shaft portion 152A on the side opposite to the tip of the shaft portion 152A, and a shaft portion of the flange portion 152B. A head portion 152C formed adjacent to the opposite side of 152A. The collar 154 is a cylindrical body having a length substantially the same as the thickness of the resin member 14.

この樹脂部材の締結構造１５０では、樹脂部材１４の孔部１４Ａにカラー１５４を挿入し、フランジボルト１５２の軸部１５２Ａをウェルドナット１３６に螺合させることで、フランジボルト１５２のフランジ部１５２Ｂが樹脂部材１４の表面に接触し、金属部材１２と樹脂部材１４とが固定される。   In the resin member fastening structure 150, the collar 154 is inserted into the hole 14A of the resin member 14, and the shaft portion 152A of the flange bolt 152 is screwed into the weld nut 136, whereby the flange portion 152B of the flange bolt 152 is made of resin. The metal member 12 and the resin member 14 are fixed in contact with the surface of the member 14.

上記のような樹脂部材の締結構造１３０、１５０では、樹脂部材１４のクリープ変形による軸力の低下を防ぐため、段付ボルト１３２、カラー１５４及びフランジボルト１５２を用いることで、樹脂部材１４に軸力を伝えない構造となっている。   In the resin member fastening structures 130 and 150 as described above, in order to prevent a reduction in the axial force due to creep deformation of the resin member 14, the stepped bolt 132, the collar 154, and the flange bolt 152 are used so that the resin member 14 has a shaft. It has a structure that does not convey power.

しかし、上記のような締結構造１３０、１５０では、特にせん断方向に大きな荷重が加わる場合、金属部材１２と樹脂部材１４との間にズレが発生する。すなわち、各部材は、精度バラツキを持っており、例えば、樹脂部材１４は、パネルの厚みや孔部１４Ａの内径、図７（Ａ）に示す段付ボルト１３２は段部１３２Ｂの外径や軸方向の高さのバラツキを持っている。また、図９に示すカラー１５４は、外径や軸方向の高さのバラツキを持っている。さらに、樹脂部材１４と金属部材１２は、互いの加工、組付精度を許容する逃がし孔の構造を持っている。   However, in the fastening structures 130 and 150 as described above, a displacement occurs between the metal member 12 and the resin member 14 particularly when a large load is applied in the shear direction. That is, each member has variation in accuracy. For example, the resin member 14 is the thickness of the panel and the inner diameter of the hole 14A, and the stepped bolt 132 shown in FIG. 7A is the outer diameter and shaft of the step 132B. Has variation in height in direction. Further, the collar 154 shown in FIG. 9 has variations in outer diameter and axial height. Furthermore, the resin member 14 and the metal member 12 have a relief hole structure that allows mutual processing and assembly accuracy.

このため、図８に示されるように、締結により一体となっている段付ボルト１３２及び金属部材１２と樹脂部材１４との間には、厚み方向の隙（フランジ部１３２Ｃと樹脂部材１４の表面との間の隙）、及び段部１３２Ｂの外壁面と孔部１４Ａの内壁面との間の隙Ｓ３が発生する。これにより、大きな荷重が加わる場合に、樹脂部材１４がせん断方向（矢印Ｄ方向）にずれる可能性がある。   For this reason, as shown in FIG. 8, gaps in the thickness direction (the surfaces of the flange portion 132 </ b> C and the surface of the resin member 14 are formed between the stepped bolt 132 and the metal member 12 and the resin member 14 that are integrated by fastening. Between the outer wall surface of the step portion 132B and the inner wall surface of the hole portion 14A. Thereby, when a big load is added, the resin member 14 may shift | deviate to a shear direction (arrow D direction).

同様に、締結により一体となっているフランジボルト１５２、カラー１５４及び金属部材１２と樹脂部材１４との間には、厚み方向の隙、及びカラー１５４の外壁面と孔部１４Ａの内壁面との間の隙が発生し、大きな荷重が加わる場合に、樹脂部材１４がせん断方向にずれる可能性がある。   Similarly, between the flange bolt 152, the collar 154, and the metal member 12 and the resin member 14 which are integrated by fastening, there is a gap in the thickness direction, and the outer wall surface of the collar 154 and the inner wall surface of the hole 14A. When a gap is generated and a large load is applied, the resin member 14 may shift in the shear direction.

これに対して、本実施形態の樹脂部材の締結構造１０では、図１に示されるように、カラー１６の突起２８が樹脂部材１４に食い込むことで、樹脂部材１４の回転や、カラー１６に対する樹脂部材１４のせん断方向のズレを防止又は抑制することができる。   In contrast, in the resin member fastening structure 10 of the present embodiment, as shown in FIG. 1, the protrusions 28 of the collar 16 bite into the resin member 14, so that the resin member 14 rotates and the resin with respect to the collar 16. Deviation in the shear direction of the member 14 can be prevented or suppressed.

本実施形態では、カラー１６に突起２８が設けられているが、第５比較例として、ボルトの頭部に突起を設ける場合も考えられる。この第５比較例では、ボルトの頭部に突起を設けることで、締結時にボルトが回転するため、ボルトに設けられた突起自体が回転しならが樹脂部材を削ることになり、突起の樹脂部材への食い込み状態が良くない。   In this embodiment, the projections 28 are provided on the collar 16. However, as a fifth comparative example, a case in which a projection is provided on the head of the bolt can be considered. In this fifth comparative example, by providing a protrusion on the head of the bolt, the bolt rotates at the time of fastening. Therefore, if the protrusion provided on the bolt itself rotates, the resin member will be scraped. The state of biting into is not good.

また、第６比較例として、第５比較例のボルトに代えて、ナットに突起を設けた場合には、突起自体が回転するため、同様に突起の樹脂部材への食い込み状態が良くない。   Further, as a sixth comparative example, when a protrusion is provided on the nut instead of the bolt of the fifth comparative example, the protrusion itself rotates, so that the protrusion is not good in the resin member.

これに対して、本実施形態では、カラー１６に突起２８を設けてボルト２０を締め付けることにより、締め付けトルクがダイレクトに入ってカラー１６の突起２８が樹脂部材１４に食い込むため、突起２８がしっかりと食い込みやすい。   On the other hand, in this embodiment, by providing the projections 28 on the collar 16 and tightening the bolts 20, the tightening torque enters directly, and the projections 28 of the collar 16 bite into the resin member 14. Easy to bite.

なお、本実施形態において、突起２８の形状は、締結時の軸力で樹脂部材１４の表面に食い込み可能な形状であれば、先端の角部の角度などの変更が可能である。   In the present embodiment, if the shape of the protrusion 28 is a shape that can bite into the surface of the resin member 14 with the axial force at the time of fastening, the angle of the corner of the tip can be changed.

また、本実施形態では、樹脂部材１４及びカラー１６の側からボルト２０が貫通され、金属部材１２の側からボルト２０の軸部２０Ａにナット２２が螺合されているが、これに限定されず、金属部材１２の側からボルトが貫通され、樹脂部材１４及びカラー１６の側からナットがボルトの軸部に螺合されることで、樹脂部材１４と金属部材１２とを締結固定する構成でもよい。   Further, in this embodiment, the bolt 20 is penetrated from the resin member 14 and the collar 16 side, and the nut 22 is screwed to the shaft portion 20A of the bolt 20 from the metal member 12 side, but is not limited thereto. The bolt may be penetrated from the metal member 12 side, and the resin member 14 and the metal member 12 may be fastened and fixed by screwing the nut into the bolt shaft from the resin member 14 and collar 16 side. .

また、本実施形態では、樹脂部材の締結構造が適用された車両用のバックドアの例を説明したが、バックドアに限定されず、樹脂部材と金属部材とを締結固定する車両用ドア、車両用のボデー本体などにも本発明を適用することができる。   Moreover, although the example of the back door for vehicles to which the fastening structure of the resin member was applied was demonstrated in this embodiment, it is not limited to a back door, The vehicle door which fastens and fixes a resin member and a metal member, vehicle The present invention can also be applied to a body body for use.

また、車両用部材に限定するものではなく、樹脂部材と金属部材とを締結固定する構造であれば、本発明を適用することができる。   In addition, the present invention is not limited to the vehicle member, and any structure can be used as long as the resin member and the metal member are fastened and fixed.
