成形条件の部分的な不揃いから偏肉を生じて均一

ましくなく、その除去作業が必要となる。
本発明は、以上のような問題点を解消し、接合

［実施例］ 以下、本発明の一実施例を図面を参照して説明
する。
第１図は自動車のエンジンに利用される吸気系
部品たる吸気管の全体を示し、第２図はそのＡ部
の断面図を示している。図面に示す吸気管１は、
サージタンクとシリンダヘツドとの間に介設さ
れ、サージタンク内の吸気を各気筒に分配するよ
うに形成されたもので、全体が強化材（ガラス繊
維等）を含んだ高分子樹脂材料（例えば６ナイロ
ン）で形成されている。
吸気管１は、金型で成形された複数の分割片２
〜５の接合面６〜９間にこれら分割片２〜５が溶
融する領域（107〜108Hz）外の誘電加熱用周波数
により昇温する物質Ｍを介在させるとともに、こ
の物質Ｍに高周波を照射して昇温させ、その物質
Ｍの熱により各接合面６〜９の所要部分を溶融さ
せて溶着し、一体化されたものである。
分割片２〜５は、吸気管本体１０〜１２とその
両端に一体形成されたフランジ１３，１４とを吸
気管本体１０〜１２の長手方向に２分割した状態
に形成されている。吸気管本体１０〜１２は、円
筒状のもので、その内部空間を吸気通路１５〜１
７としており、サージタンク側に接続されるフラ
ンジ１３の端面には吸気導入口１５ａ〜１７ａ
を、吸気ポート近傍のシリンダヘツドの側面に固
着される側のフランジ１４の端面には吸気導出口
１５ｂ〜１７ｂをそれぞれ開口させている。
一方の分割片２，４の接合面６，８には、両端
側のフランジ１３，１４の端面にかけて奥広状の
連続的な溝１８を形成してあり、これら接合面
６，８に対応する他方の分割片３，５の接合面
７，９には、両端側のフランジ１３，１４の端面
にかけて前記溝１８に嵌合する先太状の連続的な
凸条１９を形成してある。
以上のように構成された各分割片２〜５は、第
４図ａ，ｂ，ｃに概略的に示すような接合工程を
経て一体化される。
先ず、一方の分割片２，４の接合面６，８に形
成された溝１８に、これら分割片２〜５が溶融す
る領域外の高周波によつて早期に昇温する前記物
質Ｍ、例えば、鉄や銅、亜鉛、あるいはフエライ
ト等の数種の高導電性の金属粉末を均一に散布し
た後(a)、上記接合面６，８に対応する他方の分割
片３，５の凸条１９を上記溝１８に圧入して嵌合
させ、これら分割片２〜５同士を仮接合状態とす
る。しかる後、各接合部に高周波（例えば100Hz
〜10KHz）を照射してやれば、前記物質Ｍが昇温
し、その熱で周辺、すなわち溝１８の内面と凸条
１９の先端面部分が溶解して溶着される（ｂ→
ｃ）。
しかして、このような吸気管１の接合方法によ
れば、一方の分割片２，４の接合面６，８に形成
した奥広状の溝１８と、この溝１８に係合される
他方の分割片３，５の接合面７，９に形成した先
太状の凸条１９とが密着状態で嵌合するととも
に、導電性の物質Ｍが高周波によつて誘電加熱さ
れる際の熱で接合部内で溶着されることになる。
そのため、接合面６〜９の外側や内側へバリが表
出するのを確実に防止することが出来るととも
に、接合部からの吸気洩れ（過給機付エンジンの
場合）や吸気管１内への外気の進入を確実に防止
することが出来る。
しかも、溶着される接合面６〜９間では、奥広
状の溝１８と、この溝１８に係合される先太状の
凸条１９とが密着状態で相互に係止し合うような
状態で嵌合されているため、接合強度が高めら
れ、壁面に直交する面方向の内圧に対して分割片
２〜５がその接合面６〜９から外れてしまうよう
な不具合が確実に解消出来る（例えば、樹脂製分
割片の溶着工法中、最も強度を有する熱板溶着の
800Kg／cm2程の強度に対して、1200Kg／cm2程の強
度が発揮される）。その結果、接合面６〜９に強
度確保等のための格別なフランジを設ける必要も
なく、また前述したように内面は勿論、外面にも
バリが表出するようなことがないため、バリの除
去作業が不要となるとともに、接合部の表面が面
一にできること等と相まつて、外観の見栄えも良
好となる。
その上、熱板による溶着に比較して消費電力が
遥かに少ない（1/10〜1/20）点から、コストの低
下に繋がり、好都合となる。
なお、上記実施例では、分割成形された吸気管
片を溶着して吸気管を形成する場合に付いて述べ
たが、本発明は吸気管に限らず、他の吸気系部
品、例えばサージタンク等にも好適に実施可能で
ある。
また、高周波を照射した際に昇温する物質は、
鉄や銅、あるいは亜鉛等の金属性物質に限らず、
樹脂の溶ける領域外の周波数で樹脂よりも早期に
昇温して樹脂を溶解させるようなものであれば、
他の物質でも有効に実施可能である。
［考案の効果］ 以上、詳述したような本発明によると、分割成
形された吸気系部品片は、その接合面に形成され
連続的な溝と、この溝に係合する連続的な凸条と
により接合されるとともに、特定領域の周波数で
昇温する物質を介して接合部内で熱溶着される。
そのため、分割片の接合部にバリが表出するよう
な不具合が確実に解消される上に、分割片の接合
強度を確実に高めることができる。その結果、シ
ール性等に優れた信頼性の高い樹脂製の吸気系部
品を提供できるとともに、吸気系部品のコスト低
下にも繋がる。
