Description

本発明は接合方法に関し、たとえば、金属部材同士、金属部材と樹脂部材、樹脂部材同士などからなる異種部材同士を接合する接合方法に関するものである。   The present invention relates to a joining method, for example, a joining method for joining different members composed of metal members, metal members and resin members, resin members, and the like.

従来から、たとえば金属部材と樹脂部材などからなる異種部材同士を接合する方法として、接着剤を用いた方法（たとえば、特許文献１）やリベットやネジ等の締結部材を用いた方法が知られている。しかしながら、前者の方法は、接着剤の硬化に時間を要するといった問題や、接着剤の経年劣化等によって接着力が低下し得るといった問題を有している。また、後者の方法は、リベットやネジ等によって製品重量が増加するといった問題や、リベットやネジ等の締結に時間や工数を要するといった問題を有している。   Conventionally, as a method of joining different kinds of members made of, for example, a metal member and a resin member, a method using an adhesive (for example, Patent Document 1) and a method using a fastening member such as a rivet or a screw are known. Yes. However, the former method has a problem that it takes time to cure the adhesive and a problem that the adhesive force can be reduced due to deterioration of the adhesive over time. The latter method has a problem that the product weight increases due to rivets, screws, and the like, and a problem that it takes time and man-hours to fasten the rivets and screws.

このような問題に対し、接着剤や締結部材等を使用せず、たとえば超音波振動などによって接合対象となる部材の一部を変形させることで、金属部材と樹脂部材などからなる異種部材同士を接合する従来技術が知られている。   For such a problem, without using an adhesive or a fastening member, for example, by deforming a part of a member to be joined by ultrasonic vibration or the like, dissimilar members composed of a metal member and a resin member can be combined. Conventional techniques for joining are known.

このような従来の接合方法では、図４で示すように、貫通孔Ａａが形成された金属部材Ａと、該金属部材Ａの貫通孔Ａａに挿通される突起Ｂａが形成された樹脂部材Ｂと、所定形状の窪みが形成された超音波フォーンＣとを用意し、樹脂部材Ｂの突起Ｂａを金属部材Ａの貫通孔Ａａに挿通させて樹脂部材Ｂ上に金属部材Ａを載置し、超音波フォーンＣの窪みを金属部材Ａの貫通孔Ａａに挿通された樹脂部材Ｂの突起Ｂａの上端部と接触させながら当該超音波フォーンＣを金属部材Ａ側から樹脂部材Ｂへ向かって移動させ、超音波フォーンＣの超音波振動により樹脂部材Ｂの突起Ｂａを溶融させて変形させ、その樹脂部材Ｂの突起Ｂａの上端部に樹脂部材Ｂを金属部材Ａに係止するアンカー部Ｈａを有する頭部Ｈを形成して、金属部材と樹脂部材とを接合する方法である。   In such a conventional joining method, as shown in FIG. 4, a metal member A in which a through hole Aa is formed, and a resin member B in which a protrusion Ba inserted into the through hole Aa of the metal member A is formed. Then, an ultrasonic phone C having a recess of a predetermined shape is prepared, the protrusion Ba of the resin member B is inserted into the through hole Aa of the metal member A, and the metal member A is placed on the resin member B. The ultrasonic phone C is moved from the metal member A side toward the resin member B while bringing the dent of the sonic phone C into contact with the upper end of the protrusion Ba of the resin member B inserted through the through hole Aa of the metal member A. A head having an anchor portion Ha for fixing the resin member B to the metal member A at the upper end of the protrusion Ba of the resin member B by melting and deforming the protrusion Ba of the resin member B by ultrasonic vibration of the ultrasonic phone C. Forming part H, metal member and resin part A method of joining and.

しかしながら、上記した従来の接合方法では、超音波フォーンＣを金属部材Ａ側から樹脂部材Ｂへ向かって移動させながら樹脂部材Ｂの突起Ｂａを溶融させて変形させるため、変形後の樹脂部材Ｂの突起Ｂａの一部が超音波フォーンＣと金属部材Ａとの間に入り込み、樹脂部材Ｂに形成された頭部Ｈの外縁、より具体的には、樹脂部材Ｂに形成された頭部Ｈの外縁のうち超音波フォーンＣと金属部材Ａとの間の箇所でバリが発生し、そのバリ取り作業に時間や費用を要するといった問題があった。   However, in the conventional joining method described above, since the ultrasonic phone C is moved from the metal member A side toward the resin member B, the protrusion Ba of the resin member B is melted and deformed. Part of the protrusion Ba enters between the ultrasonic phone C and the metal member A, and more specifically, the outer edge of the head H formed on the resin member B, more specifically, the head H formed on the resin member B. There is a problem that burrs are generated in the outer edge between the ultrasonic phone C and the metal member A, and the deburring operation requires time and cost.

本発明は上記する問題に鑑みてなされたものであり、たとえば、金属部材同士、金属部材と樹脂部材、樹脂部材同士などからなる異種部材同士を接合するに当たり、バリの発生を確実に抑制することのできる接合方法を提供することを目的とする。   The present invention has been made in view of the above-described problems. For example, when joining different members composed of metal members, metal members and resin members, resin members, or the like, the generation of burrs is reliably suppressed. It is an object of the present invention to provide a bonding method that can be used.

前記目的を達成すべく、本発明による接合方法は、一方面から他方面に向かって貫通孔が形成された第１部材と、前記貫通孔に挿通される突起を有する第２部材と、を接合する接合方法であって、前記貫通孔の孔径よりも大きな内径を有する筒状部と該筒状部の内部に摺動自在に配置される可動部とを用意する準備工程と、前記貫通孔に前記突起を挿通させて前記第２部材を前記第１部材の一方面に配置すると共に、前記筒状部の内部と前記貫通孔とが連通するように該筒状部を前記第１部材の他方面と当接させて配置する配置工程と、前記筒状部内で前記可動部を前記突起へ向かって移動させ、該可動部を該突起と衝接させて該突起を変形させて前記第２部材を前記第１部材に係止するアンカー部を形成するアンカー部形成工程と、を含む方法である。   In order to achieve the above object, a joining method according to the present invention joins a first member having a through hole formed from one surface to the other surface and a second member having a protrusion inserted through the through hole. A preparing step of preparing a cylindrical part having an inner diameter larger than the hole diameter of the through-hole and a movable part slidably disposed inside the cylindrical part; The second member is disposed on one surface of the first member by inserting the protrusion, and the tubular portion is connected to the first member so that the inside of the tubular portion and the through hole communicate with each other. An arrangement step of placing the second member in contact with the surface, and moving the movable portion toward the projection in the cylindrical portion, and deforming the projection by bringing the movable portion into contact with the projection to deform the second member. An anchor portion forming step of forming an anchor portion that locks the first member with the first portion. It is the law.

上記する接合方法によれば、第１部材の貫通孔に第２部材の突起を挿通させて第２部材を第１部材の一方面に配置すると共に、筒状部の内部と貫通孔とが連通するようにその筒状部を第１部材の他方面と当接させて配置し、筒状部内で可動部を突起へ向かって移動させ、その可動部を突起と衝接させてその突起を変形させ、その突起に第２部材を第１部材に係止するアンカー部を形成することにより、筒状部を第１部材の他方面と当接させた状態で、筒状部と可動部と第１部材とによって画成される閉空間内で前記突起に前記アンカー部を形成できるため、第２部材の突起に形成されるアンカー部の外縁におけるバリの発生を確実に抑止しながら、第１部材と第２部材とを接合することができる。   According to the above-described joining method, the protrusion of the second member is inserted into the through hole of the first member and the second member is disposed on one surface of the first member, and the inside of the tubular portion and the through hole communicate with each other. The cylindrical portion is arranged in contact with the other surface of the first member so that the movable portion is moved toward the projection within the cylindrical portion, and the movable portion is brought into contact with the projection to deform the projection. And forming an anchor portion for locking the second member to the first member on the projection, so that the tubular portion, the movable portion, and the first portion are in contact with the other surface of the first member. Since the anchor portion can be formed on the protrusion in a closed space defined by the one member, the first member can be reliably prevented from generating burrs on the outer edge of the anchor portion formed on the protrusion of the second member. And the second member can be joined.

また、上記する接合方法の好ましい実施の形態は、前記可動部が前記筒状部内で軸線周りで回転自在となっており、前記アンカー部形成工程において、前記筒状部内で前記可動部を軸線周りで回転させながら前記突起へ向かって移動させて該可動部を該突起と衝接させる方法である。   In a preferred embodiment of the joining method described above, the movable part is rotatable around an axis within the cylindrical part, and in the anchor part forming step, the movable part is rotated around the axis within the cylindrical part. This is a method in which the movable part is brought into contact with the projection by moving the projection toward the projection while being rotated.

上記する接合方法によれば、前記アンカー部形成工程において、筒状部内で可動部を軸線周りで回転させながら突起へ向かって移動させてその可動部を第２部材の突起と衝接させることにより、その突起を比較的容易に変形させてその突起に前記アンカー部を形成することができる。   According to the joining method described above, in the anchor portion forming step, the movable portion is moved toward the projection while rotating around the axis within the cylindrical portion, and the movable portion is brought into contact with the projection of the second member. The anchor portion can be formed on the protrusion by deforming the protrusion relatively easily.

以上の説明から理解できるように、本発明の接合方法によれば、金属部材同士、金属部材と樹脂部材、樹脂部材同士などからなる異種部材同士を接合するに当たり、第１部材の貫通孔に第２部材の突起を挿通させて第２部材を第１部材の一方面に配置すると共に、筒状部の内部と貫通孔とが連通するようにその筒状部を第１部材の他方面と当接させて配置し、筒状部内で可動部を突起へ向かって移動させ、その可動部を突起と衝接させてその突起を変形させて第２部材を第１部材に係止するアンカー部を形成することで、アンカー部におけるバリの発生を確実に抑制でき、バリ取り作業に要する時間や費用を確実に削減することができる。   As can be understood from the above description, according to the joining method of the present invention, when joining different members composed of metal members, metal members and resin members, resin members, etc., the first member has a through-hole. The projection of the two members is inserted to place the second member on one surface of the first member, and the cylindrical portion is abutted against the other surface of the first member so that the inside of the cylindrical portion communicates with the through hole. An anchor portion that is disposed in contact with each other, moves the movable portion toward the projection in the cylindrical portion, makes the movable portion abut against the projection, deforms the projection, and locks the second member to the first member. By forming, the generation | occurrence | production of the burr | flash in an anchor part can be suppressed reliably, and the time and expense which a deburring operation requires can be reduced reliably.

＜本発明の接合方法の実施の形態で用いる摩擦接合装置＞
本発明の実施の形態に係る接合方法は、摩擦撹拌接合装置の代表的な一例としての単動式摩擦撹拌接合装置を用いて実施される。そのため、まず、本実施の形態に係る接合方法で用いられる単動式摩擦撹拌接合装置（ＦＳＷ：Friction Stir Welding）の代表的な一例について、図１（ａ）を参照して概説する。 <Friction welding apparatus used in the embodiment of the joining method of the present invention>
The joining method according to the embodiment of the present invention is carried out using a single-acting friction stir welding apparatus as a typical example of a friction stir welding apparatus. Therefore, first, a typical example of a single-acting friction stir welding apparatus (FSW: Friction Stir Welding) used in the joining method according to the present embodiment will be outlined with reference to FIG.

図１（ａ）に示すように、本実施の形態に係る接合方法で用いられるＦＳＷ装置５０は、主に、回転工具部（可動部）５１、クランプ部材（筒状部）５４、裏当て部材５５、図１（ａ）には示されていないが、これらを支持する支持部材、回転工具部５１を駆動する駆動機構等を備えている。クランプ部材５４は、スプリング５３を介して不図示の支持部材に固定されている。   As shown in FIG. 1A, the FSW device 50 used in the joining method according to the present embodiment mainly includes a rotary tool part (movable part) 51, a clamp member (tubular part) 54, and a backing member. 55, although not shown in FIG. 1A, includes a support member that supports them, a drive mechanism that drives the rotary tool portion 51, and the like. The clamp member 54 is fixed to a support member (not shown) via a spring 53.

回転工具部（可動部）５１は、略円柱形状を呈し、不図示の駆動機構により軸線（回転軸）Ｘｒ周りに回転するとともに、破線矢印Ｐ１方向すなわち軸線Ｘｒ方向（図１（ａ）中では上下方向）に沿ってクランプ部材５４に対して相対的に摺動自在に構成されている。   The rotary tool part (movable part) 51 has a substantially cylindrical shape, is rotated around an axis line (rotation axis) Xr by a drive mechanism (not shown), and is in the direction of the broken line arrow P1, that is, in the axis line Xr direction (in FIG. 1A). It is configured to be slidable relative to the clamp member 54 along the vertical direction.

クランプ部材（筒状部）５４は、回転工具部５１の外側に設けられ、中空を有する略円筒形状を呈し、その中空内に前記回転工具部５１が内挿されている。このクランプ部材５４は、加工材（第１部材１と第２部材２）を一方面（図１（ａ）中では第１部材１の上面１ａ）から押圧するように、スプリング５３を介して不図示の支持部材に支持されている。したがって、クランプ部材５４は、加工材側に付勢された状態で、破線矢印Ｐ２方向すなわち軸線Ｘｒ方向に移動自在に構成されている。   The clamp member (cylindrical part) 54 is provided outside the rotary tool part 51 and has a substantially cylindrical shape having a hollow. The rotary tool part 51 is inserted into the hollow. The clamp member 54 is not connected via a spring 53 so as to press the workpieces (the first member 1 and the second member 2) from one surface (the upper surface 1a of the first member 1 in FIG. 1A). It is supported by the illustrated support member. Therefore, the clamp member 54 is configured to be movable in the direction of the broken line arrow P2, that is, in the direction of the axis Xr, while being urged toward the workpiece.

上記構成の回転工具部５１およびクランプ部材５４は、それぞれ当接面５１ａ、５４ａを備え、これらの当接面５１ａ、５４ａが、不図示の駆動機構により軸線Ｘｒ方向に移動して加工材の一方面（図１（ａ）中ではそれぞれ、第２部材２の突起２ｃの上面２ｃａおよび第１部材１の上面１ａ）に当接するようになっている。   The rotary tool portion 51 and the clamp member 54 having the above-described configuration are provided with contact surfaces 51a and 54a, respectively, and these contact surfaces 51a and 54a are moved in the direction of the axis Xr by a drive mechanism (not shown), and the workpiece In this direction (in FIG. 1A), the upper surface 2ca of the protrusion 2c of the second member 2 and the upper surface 1a of the first member 1 are in contact with each other.

また、裏当て部材５５は、クランプ部材５４や回転工具部５１に対向する位置に設けられ、加工材の他方面（図１（ａ）中では第２部材２の下面２ｂ）に当接するようになっている。   The backing member 55 is provided at a position facing the clamp member 54 and the rotary tool portion 51 so as to contact the other surface of the workpiece (the lower surface 2b of the second member 2 in FIG. 1A). It has become.

なお、本実施の形態における単動式摩擦撹拌接合（ＦＳＷ）装置５０の具体的な構成は、前述した構成に限定されず、たとえば、ＦＳＷ装置５０の構成上で裏当て部材５５を省略してもよいし、前述したＦＳＷ装置５０では説明していない他の部材等を備えていてもよい。   Note that the specific configuration of the single-acting friction stir welding (FSW) device 50 in the present embodiment is not limited to the above-described configuration. For example, the backing member 55 is omitted from the configuration of the FSW device 50. Alternatively, other members that are not described in the FSW device 50 described above may be provided.

＜摩擦接合装置を用いた接合方法＞
次に、本実施の形態に係るＦＳＷ装置５０を用いた接合方法について、図１を参照して概説する。この実施の形態では、金属部材、樹脂部材、木材などからなる略平板状の第１部材１と、第１部材１の形成素材よりも溶融温度の低い素材を含む金属部材や樹脂部材などからなる略平板状の第２部材２と、を接合する方法について具体的に説明する。 <Joint method using friction welding device>
Next, a joining method using the FSW device 50 according to the present embodiment will be outlined with reference to FIG. In this embodiment, it consists of a substantially flat plate-like first member 1 made of a metal member, a resin member, wood, or the like, and a metal member, a resin member, or the like containing a material having a melting temperature lower than that of the forming material of the first member 1. A method of joining the substantially flat second member 2 will be specifically described.

本実施の形態に係る接合方法は、主に、準備工程と、配置工程と、アンカー部形成工程と、取外し工程とを含んでいる。   The joining method according to the present embodiment mainly includes a preparation process, an arrangement process, an anchor portion formation process, and a removal process.

まず、準備工程では、一方面（図１中では下面）１ｂから他方面（図１中では上面）１ａに向かって直線状の貫通孔１ｃが形成された第１部材１と、第１部材１の貫通孔１ｃに挿通される突起２ｃがその上面２ａに一体に形成された第２部材２と、上述したＦＳＷ装置５０と、を用意する。   First, in the preparation step, a first member 1 in which a linear through hole 1c is formed from one surface (lower surface in FIG. 1) 1b toward the other surface (upper surface in FIG. 1) 1a, and the first member 1 A second member 2 in which a protrusion 2c inserted through the through hole 1c is integrally formed on the upper surface 2a and the FSW device 50 described above are prepared.

ここで、第１部材１の貫通孔１ｃおよび第２部材２の突起２ｃは、断面略円形状を呈しており、ＦＳＷ装置５０のクランプ部材５４は、前記第１部材１の貫通孔１ｃの孔径よりも大きな内径を有している。また、第２部材２の突起２ｃは、その上下方向（軸線Ｘｒ方向）の高さが第１部材１の上下方向の厚さよりも大きく形成されると共に、その体積が第１部材１の貫通孔１ｃの体積よりも大きく形成されている。   Here, the through hole 1c of the first member 1 and the protrusion 2c of the second member 2 have a substantially circular cross section, and the clamp member 54 of the FSW device 50 has a hole diameter of the through hole 1c of the first member 1. Has a larger inner diameter. Further, the protrusion 2 c of the second member 2 is formed such that the height in the vertical direction (axis Xr direction) is larger than the thickness in the vertical direction of the first member 1, and the volume thereof is a through hole of the first member 1. It is formed larger than the volume of 1c.

次に、配置工程では、図１（ａ）で示すように、第１部材１の貫通孔１ｃに第２部材２の突起２ｃを挿通させ且つ第１部材１の下面１ｂと第２部材２の上面２ａとが当接するように、第１部材１の下面１ｂに第２部材２を配置する。また、第１部材１の貫通孔１ｃを覆うように、すなわち、クランプ部材５４の内部と第１部材１の貫通孔１ｃとが連通するように、クランプ部材５４の当接面５４ａを第１部材１の上面１ａと当接させて第１部材１の上面１ａにＦＳＷ装置５０のクランプ部材５４を配置する。なお、第２部材２の下面２ｂ側にはＦＳＷ装置５０の裏当て部材５５を配置し、クランプ部材５４と裏当て部材５５とによって第１部材１および第２部材２を挟持する。   Next, in the arrangement step, as shown in FIG. 1A, the protrusion 2 c of the second member 2 is inserted into the through hole 1 c of the first member 1, and the lower surface 1 b of the first member 1 and the second member 2 are inserted. The second member 2 is disposed on the lower surface 1b of the first member 1 so that the upper surface 2a contacts. Further, the contact surface 54a of the clamp member 54 is made to cover the first member 1 so as to cover the through hole 1c of the first member 1, that is, the inside of the clamp member 54 and the through hole 1c of the first member 1 communicate with each other. The clamp member 54 of the FSW device 50 is disposed on the upper surface 1 a of the first member 1 in contact with the upper surface 1 a of the first member 1. A backing member 55 of the FSW device 50 is disposed on the lower surface 2 b side of the second member 2, and the first member 1 and the second member 2 are sandwiched between the clamp member 54 and the backing member 55.

次に、アンカー部形成工程では、図１（ｂ）で示すように、クランプ部材５４内で回転工具部５１を軸線Ｘｒ周りに回転させながらその回転工具部５１を軸線Ｘｒ方向に沿って下方へ移動させ、その回転工具部５１の当接面５１ａを第１部材１の貫通孔１ｃから突出した突起２ｃの上面２ｃａと衝接させる。これにより、回転工具部５１の当接面５１ａと突起２ｃの上面２ｃａとの間で生じる摩擦熱を利用して当該突起２ｃが軟化もしくは溶融されて変形される。回転工具部５１を第１部材１の上面１ａから所定の距離だけ離間する位置まで移動させると、第２部材２の突起２ｃの上端部に、第２部材２を第１部材１に係止するアンカー部２ｈａを有する頭部２ｈが形成される。なお、この頭部２ｈのアンカー部２ｈａは、第１部材１の貫通孔１ｃの上方かつ周囲に向かって拡がるように第１部材１の上面１ａ上に形成され、頭部２ｈは、第１部材１の貫通孔１ｃよりも大きい外形を有することとなる。   Next, in the anchor part forming step, as shown in FIG. 1B, the rotary tool part 51 is moved downward along the axis Xr direction while rotating the rotary tool part 51 around the axis Xr in the clamp member 54. The contact surface 51a of the rotary tool portion 51 is brought into contact with the upper surface 2ca of the projection 2c protruding from the through hole 1c of the first member 1. Thereby, the protrusion 2c is softened or melted and deformed by using frictional heat generated between the contact surface 51a of the rotary tool portion 51 and the upper surface 2ca of the protrusion 2c. When the rotary tool 51 is moved to a position separated from the upper surface 1 a of the first member 1 by a predetermined distance, the second member 2 is locked to the first member 1 at the upper end of the protrusion 2 c of the second member 2. A head 2h having an anchor portion 2ha is formed. The anchor portion 2ha of the head portion 2h is formed on the upper surface 1a of the first member 1 so as to expand above and around the through hole 1c of the first member 1, and the head portion 2h is the first member. The outer shape is larger than the one through hole 1c.

そして、取外し工程では、図１（ｃ）で示すように、回転工具部５１の回転を停止し、軟化もしくは溶融された第２部材の突起２ｃを硬化させた後、第１部材１および第２部材２からＦＳＷ装置５０を取り外す。これにより、第２部材２の突起２ｃが変形されてなる頭部２ｈ、より具体的にはその頭部２ｈの外周側に第１部材１の上面１ａ上で形成されるアンカー部２ｈａを介して、第１部材１および第２部材２が一体に接合されることとなる。   In the removal step, as shown in FIG. 1C, the rotation of the rotary tool portion 51 is stopped, the softened or melted projection 2c of the second member is cured, and then the first member 1 and the second member The FSW device 50 is removed from the member 2. Thereby, the head 2h formed by deforming the protrusion 2c of the second member 2, more specifically, via the anchor portion 2ha formed on the upper surface 1a of the first member 1 on the outer peripheral side of the head 2h. The first member 1 and the second member 2 are joined together.

このように、本実施の形態の接合方法によれば、第１部材１の貫通孔１ｃに第２部材２の突起２ｃを挿通させて第２部材２を第１部材１の下面１ｂ側に配置すると共に、クランプ部材５４の内部と第１部材１の貫通孔１ｃとが連通するようにクランプ部材５４の当接面５４ａを第１部材１の上面１ａと当接させて第１部材１の上面１ｃ側にＦＳＷ装置５０の回転工具部５１およびクランプ部材５４を配置し、ＦＳＷ装置５０のクランプ部材５４内で回転工具部５１を第２部材２の突起２ｃへ向かって移動させ、その回転工具部５１をその突起２ｃと衝接させてその突起２ｃを変形させ、その突起２ｃの上端部に第２部材２を第１部材１に係止するアンカー部２ｈａを形成することにより、ＦＳＷ装置５０のクランプ部材５４を第１部材１の上面１ａと当接させた状態で、クランプ部材５４と該クランプ部材５４の内部を摺動する回転工具部５１と第１部材１とによって画成される閉空間内で前記突起２ｃにアンカー部２ｈａを形成することができる。そのため、第２部材２のアンカー部２ｈａにおけるバリの発生を抑制しながら、異種部材からなる第１部材１と第２部材２とを精緻に接合することができる。   Thus, according to the joining method of the present embodiment, the projection 2c of the second member 2 is inserted into the through hole 1c of the first member 1, and the second member 2 is disposed on the lower surface 1b side of the first member 1. In addition, the contact surface 54a of the clamp member 54 is brought into contact with the upper surface 1a of the first member 1 so that the inside of the clamp member 54 and the through hole 1c of the first member 1 communicate with each other. The rotary tool portion 51 and the clamp member 54 of the FSW device 50 are arranged on the 1c side, the rotary tool portion 51 is moved toward the protrusion 2c of the second member 2 in the clamp member 54 of the FSW device 50, and the rotary tool portion. 51 is brought into contact with the projection 2c to deform the projection 2c, and an anchor portion 2ha for locking the second member 2 to the first member 1 is formed at the upper end of the projection 2c. Clamp member 54 on first member 1 The anchor portion 2ha is attached to the protrusion 2c in a closed space defined by the clamp member 54, the rotary tool portion 51 that slides inside the clamp member 54, and the first member 1 in a state of being in contact with 1a. Can be formed. Therefore, it is possible to precisely join the first member 1 and the second member 2 made of different members while suppressing the generation of burrs in the anchor portion 2ha of the second member 2.

なお、上記した実施の形態では、略平板状の第１部材１と略平板状の第２部材２とを接合する方法について説明したが、接合対象となる各部材の形状は適宜に設定することができることは勿論である。   In the above-described embodiment, the method of joining the substantially flat plate-like first member 1 and the substantially flat plate-like second member 2 has been described, but the shape of each member to be joined should be set appropriately. Of course you can.

また、第１部材１に設けられた貫通孔１ｃや第２部材２に設けられた突起２ｃの形状（縦断面形状や横断面形状）は、第１部材１と第２部材２との接合強度等に応じて適宜に設計することができる。たとえば、上記した実施の形態では、第１部材１に設けられた貫通孔１ｃおよび第２部材２に設けられた突起２ｃの横断面形状を略円形状としたが、略楕円形状や略長穴形状、四角形状などの多角形状等であってもよいことは勿論である。また、上記した実施の形態では、第１部材１に設けられた貫通孔１ｃおよび第２部材２に設けられた突起２ｃが上下方向（軸線Ｘｒ方向、第１部材１および第２部材２の厚さ方向）に沿って直線状を呈しているが、図２（ａ）〜（ｃ）で示すように、たとえば第１部材１'の貫通孔１ｃ'を、下面１ｂ'から上面'１ａに向かって連続的もしくは段階的に縮径して形成していてもよい。また、その場合には、たとえば図２（ｂ）で示すように、回転工具部５１を第１部材１'の上面１ａ'と当接する位置まで移動させ、第２部材２'の突起２ｃ'を変形させて、第１部材１'の貫通孔１ｃ'内で第２部材２'を第１部材１'に係止するアンカー部２ｈａ'を形成してもよいし、上記した実施の形態と同様に、第１部材１'の上面１ａ'上でも第２部材２'を第１部材１'に係止するアンカー部を形成してもよい。   Further, the shape (vertical cross-sectional shape or cross-sectional shape) of the through-hole 1 c provided in the first member 1 or the protrusion 2 c provided in the second member 2 is the bonding strength between the first member 1 and the second member 2. It can design suitably according to etc. For example, in the above-described embodiment, the cross-sectional shape of the through hole 1c provided in the first member 1 and the protrusion 2c provided in the second member 2 is substantially circular, but it is substantially elliptical or substantially elongated. Needless to say, the shape may be a polygonal shape such as a square shape. In the above-described embodiment, the through hole 1c provided in the first member 1 and the protrusion 2c provided in the second member 2 are arranged in the vertical direction (the direction of the axis Xr, the thickness of the first member 1 and the second member 2). 2 (a) to (c), for example, the through hole 1c 'of the first member 1' is directed from the lower surface 1b 'to the upper surface' 1a. Alternatively, the diameter may be reduced continuously or stepwise. In that case, for example, as shown in FIG. 2 (b), the rotary tool portion 51 is moved to a position where it contacts the upper surface 1a ′ of the first member 1 ′, and the protrusion 2c ′ of the second member 2 ′ is moved. The anchor member 2ha ′ that locks the second member 2 ′ to the first member 1 ′ may be formed in the through hole 1c ′ of the first member 1 ′ by deformation, as in the above-described embodiment. In addition, an anchor portion for locking the second member 2 ′ to the first member 1 ′ may be formed also on the upper surface 1a ′ of the first member 1 ′.

また、上記した実施の形態では、第２部材２の突起２ｃの上下方向の高さが第１部材１の上下方向の厚さよりも大きく形成され、第１部材１の下面１ｂに第２部材２を配置した際に第１部材１の貫通孔１ｃから突起２ｃの上面２ｃａが突出する形態について説明したが、第２部材２の突起２ｃを変形させた際にその突起２ｃに第２部材２を第１部材１に係止するアンカー部２ｈａが形成されれば、第１部材１の下面１ｂに第２部材２を配置した際に第２部材２の突起２ｃの上面２ｃａが第１部材１の貫通孔１ｃから突出していなくてもよいことは勿論である。   In the above-described embodiment, the vertical height of the protrusion 2 c of the second member 2 is formed larger than the vertical thickness of the first member 1, and the second member 2 is formed on the lower surface 1 b of the first member 1. The upper surface 2ca of the protrusion 2c protrudes from the through hole 1c of the first member 1 when the first member 1 is disposed. However, when the protrusion 2c of the second member 2 is deformed, the second member 2 is attached to the protrusion 2c. If the anchor portion 2 ha that is locked to the first member 1 is formed, the upper surface 2 ca of the protrusion 2 c of the second member 2 is the surface of the first member 1 when the second member 2 is disposed on the lower surface 1 b of the first member 1. Of course, it does not need to protrude from the through-hole 1c.

また、上記した実施の形態に係る接合方法は、接合対象となる部材の種類に特に限定されないが、突起２ｃを有する第２部材２が、第１部材１の形成素材よりも溶融温度の低い樹脂（マトリックス樹脂）内に強化用の繊維材が混合されてなる繊維強化樹脂部材からなる場合、図３で示すように、第２部材２の突起２ｃの内部（図３中の領域Ｒ１）や第２部材２の上面２ａと第１部材１の下面１ｂとの当接面（界面）近傍（図３中の領域Ｒ２）で、第２部材２に含有される繊維材がその当接面に略直交する方向へ配向されることとなるため、第１部材１と第２部材２の接合強度を十分に確保し得ると考えられる。   In addition, the joining method according to the above-described embodiment is not particularly limited to the type of member to be joined, but the second member 2 having the protrusion 2c is a resin having a melting temperature lower than that of the first member 1 forming material. In the case of a fiber reinforced resin member in which a reinforcing fiber material is mixed in (matrix resin), as shown in FIG. 3, the inside of the protrusion 2c of the second member 2 (region R1 in FIG. 3) and the second Near the contact surface (interface) between the upper surface 2a of the two members 2 and the lower surface 1b of the first member 1 (region R2 in FIG. 3), the fiber material contained in the second member 2 is substantially on the contact surfaces. It is considered that the bonding strength between the first member 1 and the second member 2 can be sufficiently secured because they are oriented in the orthogonal direction.
