Abstract

A baffle plate (11) of a baffle member (10) is sandwiched by an upper member (2) and a lower member (3), and during welding of the upper member (2) and the lower member (3) by vibration welding, becomes welded to the upper member (2) through vibration welding. A tongue-and groove mating part (15) in which the baffle plate (11) and the lower member (3) are mated with one another is formed along a tongue-and groove mating surface perpendicular to the welded surface (4), between the baffle plate (11) and the lower member (3). In so doing, when the baffle plate (11) attempts to deform, deformation of the baffle plate (11) is inhibited by planar contact of the baffle plate (11) and the lower member (3) along the tongue-and groove mating surface, so that stresses acting on the welded surface (4) due to deformation of the baffle plate (11) can be relatively reduced.

Description

仕切部材の取付構造Partition member mounting structure
　本発明は、ケーシングの内部空間に配置される仕切部材のケーシングに対する取付構造に関する。 This invention relates to the attachment structure with respect to the casing of the partition member arrange | positioned in the internal space of a casing.
　例えば、特許文献１には、第１部材と第２部材とを溶着してなるケーシングの内部空間が仕切板で区画された構成が開示されている。この特許文献１においては、上記第１部材と上記第２部材とによって挟み込まれた仕切板が、上記第１部材と上記第２部材のうちの一方に対して溶着されている。 For example, Patent Document 1 discloses a configuration in which an internal space of a casing formed by welding a first member and a second member is partitioned by a partition plate. In Patent Document 1, a partition plate sandwiched between the first member and the second member is welded to one of the first member and the second member.
　しかしながら、上記仕切板は、上記第１部材と上記第２部材に挟み込まれる外周端部が平板状に形成されているため、仕切板がケーシング内で上記第１部材側に凸となるように変形したり、あるいは上記第２部材側に凸となるように変形した場合、上記仕切板の外周端部もそれに伴い変形し易くなっている。つまり、上記ケーシング内で上記仕切板が変形すると、上記第１部材と上記第２部材とが互いに溶着している部分には、上記仕切板の外周端部の変形に伴う応力が作用する。そのため、上記仕切板の変形の影響により、上記第１部材と上記第２部材とが互いに溶着している部分に作用する応力が相対的に増加してしまう虞がある。 However, since the outer peripheral end sandwiched between the first member and the second member is formed in a flat plate shape, the partition plate is deformed so as to protrude toward the first member in the casing. Or when deformed to be convex toward the second member, the outer peripheral end of the partition plate is easily deformed accordingly. That is, when the partition plate is deformed in the casing, a stress accompanying deformation of the outer peripheral end portion of the partition plate acts on a portion where the first member and the second member are welded to each other. For this reason, the stress acting on the portion where the first member and the second member are welded to each other may be relatively increased due to the deformation of the partition plate.

　そこで、本発明は、第１部材と第２部材とを溶着してなるケーシングの内部空間に配置される仕切部材であって、上記第１部材と上記第２部材とに挟持されると共に、上記第１部材と上記第２部材との溶着面を含む平面上で上記第１部材に溶着される仕切部材の取付構造において、上記第１部材と上記第２部材とに挟持される上記仕切部材の挟持部と上記第２部材との間には、上記溶着面に対して直交する凹凸係合面に沿って上記仕切部材と上記第２部材とが互いに係合する凹凸係合部が形成されていることを特徴としている。 Therefore, the present invention is a partition member disposed in the internal space of the casing formed by welding the first member and the second member, and is sandwiched between the first member and the second member, and In the mounting structure of the partition member welded to the first member on a plane including the welding surface of the first member and the second member, the partition member sandwiched between the first member and the second member. An uneven engagement portion is formed between the sandwiching portion and the second member so that the partition member and the second member engage with each other along an uneven engagement surface orthogonal to the welding surface. It is characterized by being.
　上記凹凸係合部及び上記凹凸係合面は、より具体的には、上記挟持部の長手方向に沿って形成されている。 More specifically, the concave and convex engaging portion and the concave and convex engaging surface are formed along the longitudinal direction of the sandwiching portion.
　そして、上記凹凸係合部は、より具体的には、上記仕切部材に設けた凸部と上記第２部材に設けた凹部とによって構成されている。また、上記凹凸係合部は、上記仕切部材に設けた凹部と、上記第２部材に設けた凸部とによって構成するようにしてもよい。 More specifically, the concavo-convex engaging portion is constituted by a convex portion provided on the partition member and a concave portion provided on the second member. Moreover, you may make it comprise the said uneven | corrugated engaging part by the recessed part provided in the said partition member, and the convex part provided in the said 2nd member.
　本発明によれば、仕切部材が変形しようとした際に、凹凸係合面に沿って仕切部材と第２部材とが面接触することになるため、仕切部材の変形を抑制することが可能となる。そのため、ケーシング内での仕切部材の変形が抑制されることにより、仕切部材の変形に起因して第１部材と第２部材との溶着面に作用する応力を相対的に低減することができる。 According to the present invention, when the partition member is about to be deformed, the partition member and the second member are brought into surface contact along the concave-convex engagement surface, so that the deformation of the partition member can be suppressed. Become. Therefore, by suppressing the deformation of the partition member in the casing, it is possible to relatively reduce the stress acting on the welding surface between the first member and the second member due to the deformation of the partition member.

　以下、本発明の一実施例を図面に基づいて詳細に説明する。図１及び図２は、本発明が適用された合成樹脂製の吸気マニホールド１の概略を示す断面図である。 Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. 1 and 2 are cross-sectional views schematically showing a synthetic resin intake manifold 1 to which the present invention is applied.
　吸気マニホールド１（ケーシングに相当）は、４気筒の内燃機関（図示せず）に接続されるものであって、それぞれ個別に金型成形されたアッパ部材２（第１部材に相当）とロア部材３（第２部材に相当）とを振動溶着により溶着面４で互いに接合することで構成される。この吸気マニホールド１は、気筒列方向に沿って細長いコレクタ部５と、上記内燃機関の気筒数に応じた数の吸気経路６が形成されたブランチ部７と、を有してなり、コレクタ部５内にインタークーラ８が内蔵されている。 An intake manifold 1 (corresponding to a casing) is connected to a four-cylinder internal combustion engine (not shown), and is individually molded with an upper member 2 (corresponding to a first member) and a lower member. 3 (corresponding to the second member) are joined to each other on the welding surface 4 by vibration welding. The intake manifold 1 includes an elongated collector portion 5 along the cylinder row direction, and a branch portion 7 in which a number of intake passages 6 corresponding to the number of cylinders of the internal combustion engine are formed. An intercooler 8 is built in.
　インタークーラ８は、コレクタ部５に開口形成されたインタークーラ挿入口９から挿入されている。インタークーラ挿入口９は、インタークーラ８に取り付けられた矩形板状の蓋部８ａによって閉塞される。インタークーラ８は、吸気マニホールド１の上流側に配置された過給機（図示せず）によって過給されて昇温した吸気を冷却するものである。 The intercooler 8 is inserted from an intercooler insertion opening 9 formed in the collector portion 5. The intercooler insertion port 9 is closed by a rectangular plate-shaped lid portion 8 a attached to the intercooler 8. The intercooler 8 cools intake air that has been supercharged and heated by a supercharger (not shown) arranged upstream of the intake manifold 1.
　そして、コレクタ部５内のインタークーラ８上流側には、整流部材１０が配置されている。整流部材１０は、アッパ部材２とロア部材３に挟持され、振動溶着によりアッパ部材２とロア部材３とを溶着する際に、アッパ部材２に対して振動溶着により溶着される（詳細は後述）。 Further, a rectifying member 10 is disposed upstream of the intercooler 8 in the collector unit 5. The rectifying member 10 is sandwiched between the upper member 2 and the lower member 3, and is welded to the upper member 2 by vibration welding when the upper member 2 and lower member 3 are welded by vibration welding (details will be described later). .
　整流部材１０は、図２～図５に示すように、インタークーラ８全体に効率よく吸気が導入されるように設けられた矩形板状の複数（本実施例では２つ）の整流板１１、１１（仕切部材に相当）と、これら整流板１１、１１を連結する矩形板状の複数（本実施例では３つ）の連結板１２、１２、１２と、を有している。 As shown in FIGS. 2 to 5, the rectifying member 10 includes a plurality of rectangular plate-like (two in this embodiment) rectifying plates 11 provided so that intake air is efficiently introduced into the entire intercooler 8. 11 (corresponding to a partition member) and a plurality of (three in the present embodiment) connecting plates 12, 12, and 12 in the shape of a rectangular plate connecting the rectifying plates 11 and 11.
　整流板１１には、その両端（図３～図５の上下方向における両端）よりも内側に位置して、コレクタ部５の内壁面に対して離間するよう設定された隔壁１３が設けられている。また、整流板１１、１１は、その両端が全幅に亙ってアッパ部材２とロア部材３に挟持される挟持部１４となっている。 The rectifying plate 11 is provided with a partition wall 13 that is located on the inner side of both ends (both ends in the vertical direction in FIGS. 3 to 5) and is set apart from the inner wall surface of the collector portion 5. . Further, the rectifying plates 11, 11 serve as clamping portions 14 that are sandwiched between the upper member 2 and the lower member 3 over the entire width of both ends thereof.
　そして、挟持部１４とロア部材３との間には、挟持部１４の長手方向に沿って形成され、互いに係合する凹凸係合部１５が形成されている。凹凸係合部１５は、図６及び図７に示すように、挟持部１４の一方の面（組み付け時においてロア部材３側となる面）に形成された凸部１６と、ロア部材３の開口縁に形成された凹部１７とによって構成されている。 And between the clamping part 14 and the lower member 3, the uneven | corrugated engaging part 15 formed along the longitudinal direction of the clamping part 14 and engaging with each other is formed. As shown in FIGS. 6 and 7, the concave / convex engaging portion 15 includes a convex portion 16 formed on one surface of the clamping portion 14 (a surface on the lower member 3 side during assembly), and an opening of the lower member 3. It is comprised by the recessed part 17 formed in the edge.
　凸部１６は、略矩形の突起であり、アッパ部材２とロア部材３とが接合される溶着面４に対して直交する方向に突出するよう形成されている。凹部１７は、略矩形の凹みであり、アッパ部材２とロア部材３とが接合される溶着面４に対して直交する方向に凹むように形成されている。 The convex portion 16 is a substantially rectangular protrusion, and is formed so as to protrude in a direction orthogonal to the welding surface 4 to which the upper member 2 and the lower member 3 are joined. The recess 17 is a substantially rectangular recess and is formed so as to be recessed in a direction orthogonal to the welding surface 4 to which the upper member 2 and the lower member 3 are joined.
　詳述すると、凸部１６は、溶着面４に対して直交する内側面１６ａ及び外側面１６ｂを有している。これら内側面１６ａ及び外側面１６ｂは、挟持部１４の幅方向（長手方向）に沿って形成されている。内側面１６ａは、外側面１６ｂよりも整流板１１の内側に位置している。一方、凹部１７は、溶着面４に対して直交する内側面１７ａ及び外側面１７ｂを有している。これら内側面１７ａ及び外側面１７ｂは、挟持部１４の幅方向（長手方向）に沿うように、ロア部材３外周縁の周方向に沿って形成されている。内側面１７ａは、外側面１７ｂよりもロア部材３の内側に位置している。 Specifically, the convex portion 16 has an inner surface 16 a and an outer surface 16 b that are orthogonal to the welding surface 4. The inner side surface 16 a and the outer side surface 16 b are formed along the width direction (longitudinal direction) of the sandwiching portion 14. The inner side surface 16a is located inside the rectifying plate 11 with respect to the outer side surface 16b. On the other hand, the concave portion 17 has an inner surface 17 a and an outer surface 17 b that are orthogonal to the welding surface 4. The inner side surface 17a and the outer side surface 17b are formed along the circumferential direction of the outer peripheral edge of the lower member 3 so as to be along the width direction (longitudinal direction) of the sandwiching portion 14. The inner side surface 17a is located inside the lower member 3 with respect to the outer side surface 17b.
　そして、凹凸係合部１５においては、互いに対向する凸部１６の内側面１６ａと凹部１７の内側面１７ａとが係合すると共に、互いに対向する凸部１６の外側面１６ｂと凹部１７の外側面１７ｂとが係合する。つまり、互いに対向する凸部１６の内側面１６ａと凹部１７の内側面１７ａは、アッパ部材２とロア部材３とが接合される溶着面４に対して直交し、かつ挟持部１４の長手方向に沿った凹凸係合面となっている。また、互いに対向する凸部１６の外側面１６ｂと凹部１７の外側面１７ｂも、同様に、アッパ部材２とロア部材３とが接合される溶着面４に対して直交し、かつ挟持部１４の長手方向に沿った凹凸係合面となっている。 And in the uneven | corrugated engaging part 15, while the inner surface 16a of the convex part 16 and the inner surface 17a of the recessed part 17 which mutually oppose are engaged, the outer surface 16b of the convex part 16 and the outer surface of the recessed part 17 which mutually oppose 17b is engaged. That is, the inner side surface 16 a of the convex portion 16 and the inner side surface 17 a of the concave portion 17 that face each other are orthogonal to the welding surface 4 to which the upper member 2 and the lower member 3 are joined, and in the longitudinal direction of the sandwiching portion 14. It is an uneven engagement surface along. Similarly, the outer surface 16b of the convex portion 16 and the outer surface 17b of the concave portion 17 that face each other are also orthogonal to the welding surface 4 to which the upper member 2 and the lower member 3 are joined, and It is a concave-convex engaging surface along the longitudinal direction.
　凸部１６には、凸部１６の内側面１６ａと凸部１６の先端面１６ｃとが交差する角部を斜めに切り落とした形をなす傾斜面１６ｄが形成されている。そして、凹部１７の内側開口縁は、凸部１６の傾斜面１６ｄと同じ傾きの傾斜面１７ｃとなるように形成されている。そのため、凸部１６の凹部１７への挿入が容易となり、整流部材１０のロア部材３への組み付け性が向上している。 The convex portion 16 is formed with an inclined surface 16d that is formed by obliquely cutting off a corner portion where the inner surface 16a of the convex portion 16 and the tip surface 16c of the convex portion 16 intersect. The inner opening edge of the concave portion 17 is formed to be an inclined surface 17 c having the same inclination as the inclined surface 16 d of the convex portion 16. Therefore, the insertion of the convex portion 16 into the concave portion 17 is facilitated, and the assembling property of the rectifying member 10 to the lower member 3 is improved.
　なお、挟持部１４は、アッパ部材２とロア部材３との溶着面４を含む平面上でアッパ部材２に対して溶着されている。この第１実施例では、挟持部１４のうち、凸部１６が設けられた面の反対側がアッパ部材２に対して溶着される溶着面１８となっている。つまり、この溶着面１８で、整流部材１０がアッパ部材２に対して溶着される。また、図３及び図７中の１９は、凸部１６と隔壁１３とを連結する補強用のリブであり、図６中の２０は、リブ１９に対応して形成された凹溝である。ここで、リブ１９は必ずしも必要なものではなく、場合によっては省略可能である。従って、リブ１９を設けない場合には、凹溝２０も省略されることになる。また、図３及び図７中の２１は、ロア部材３の開口縁に面接触する整流板１１の外周端面であり、この外周端面２１は凸部１６の外側面１６ｂよりも整流板１１の外側に位置している。 Note that the sandwiching portion 14 is welded to the upper member 2 on a plane including the welding surface 4 between the upper member 2 and the lower member 3. In the first embodiment, the opposite side of the surface on which the convex portion 16 is provided in the sandwiching portion 14 is a welding surface 18 to be welded to the upper member 2. That is, the rectifying member 10 is welded to the upper member 2 at the welding surface 18. 3 and 7 is a reinforcing rib for connecting the convex portion 16 and the partition wall 13, and 20 in FIG. 6 is a concave groove formed corresponding to the rib 19. Here, the rib 19 is not necessarily required, and may be omitted depending on circumstances. Therefore, when the rib 19 is not provided, the concave groove 20 is also omitted. 3 and 7 is an outer peripheral end surface of the rectifying plate 11 in surface contact with the opening edge of the lower member 3, and this outer peripheral end surface 21 is outside the rectifying plate 11 than the outer surface 16 b of the convex portion 16. Is located.
　ここで、図８及び図９に示す比較例は、アッパ部材４２とロア部材４３とを溶着してなるケーシング４１の内部空間が矩形板状の仕切板４４で区画されたものである。この比較例では、仕切板４４の両端がアッパ部材４２とロア部材４３とに挟持されるものの、これら両部材４２、４３に挟持される仕切板４４両端の挟持部４５ａ、４５ｂに、上述した本発明の凹凸係合部１５の凸部１６あるいは凹部１７に相当する構成が設けられておらず、またロア部材４３にも本発明の凹凸係合部１５の凸部１６あるいは凹部１７に相当する構成が設けられていない。また、挟持部４５は、アッパ部材４２とロア部材４３との溶着面４６を含む平面上で、挟持部４５の一方の面がアッパ部材４２に対して溶着されている。なお、この比較例においても、アッパ部材４２とロア部材４３との溶着、並びに仕切板４４とアッパ部材４２との溶着は、双方とも振動溶着によるものとする。 Here, in the comparative example shown in FIGS. 8 and 9, the internal space of the casing 41 formed by welding the upper member 42 and the lower member 43 is partitioned by a rectangular partition plate 44. In this comparative example, although both ends of the partition plate 44 are sandwiched between the upper member 42 and the lower member 43, the above-described book is provided in the sandwiching portions 45a and 45b at both ends of the partition plate 44 sandwiched between the both members 42 and 43. The configuration corresponding to the convex portion 16 or the concave portion 17 of the concave / convex engaging portion 15 of the invention is not provided, and the lower member 43 also corresponds to the convex portion 16 or the concave portion 17 of the concave / convex engaging portion 15 of the present invention. Is not provided. Further, the clamping part 45 is welded to the upper member 42 on one plane of the clamping part 45 on a plane including the welding surface 46 between the upper member 42 and the lower member 43. Also in this comparative example, the welding between the upper member 42 and the lower member 43 and the welding between the partition plate 44 and the upper member 42 are both performed by vibration welding.
　このような比較例においては、例えばケーシング４１内の圧力が上昇し、ケーシング４１及び仕切板４４が変形すると、アッパ部材４２とロア部材４３との溶着面４６には、ケーシング４１の変形に伴う応力のみならず、仕切板４４の変形に起因する応力も作用することになる。例えば、図９に示すように、仕切板４４が、一端側の挟持部４５ａから他端側の挟持部４５ｂに向かう間で、アッパ部材４２側に向かって凸（図９における上方に向かって凸）となるよう変形すると、このような仕切板４４の変形に起因して、溶着面４６には、アッパ部材４２とロア部材４３とを離間させる方向に応力が作用する。なお、図示はしないが、仕切板４４が、一端側の挟持部４５ａから他端側の挟持部４５ｂに向かう間で、ロア部材４３側に向かって凸（図９における下方側に向かって凸）となるよう変形しても、このような仕切板４４の変形に起因して、溶着面４６には、アッパ部材４２とロア部材４３とを離間させる方向に応力が作用することになる。つまり、このような比較例の溶着面４６においては、仕切板４４の変形の影響により、アッパ部材４２とロア部材４３とを離間させる方向に、相対的により大きな応力が作用する可能性がある。 In such a comparative example, for example, when the pressure in the casing 41 rises and the casing 41 and the partition plate 44 are deformed, the stress caused by the deformation of the casing 41 is applied to the welding surface 46 between the upper member 42 and the lower member 43. Not only that, the stress due to the deformation of the partition plate 44 also acts. For example, as shown in FIG. 9, the partition plate 44 protrudes toward the upper member 42 while protruding from the one end side clamping portion 45 a to the other end side clamping portion 45 b (projecting upward in FIG. 9). ) Due to the deformation of the partition plate 44, a stress acts on the welding surface 46 in a direction in which the upper member 42 and the lower member 43 are separated from each other. Although not shown, the partition plate 44 protrudes toward the lower member 43 while projecting from the one end side sandwiching portion 45a to the other end side sandwiching portion 45b (projecting downward in FIG. 9). Even if deformed, the stress acts on the welding surface 46 in the direction of separating the upper member 42 and the lower member 43 due to the deformation of the partition plate 44. That is, relatively large stress may act on the welding surface 46 of such a comparative example in the direction in which the upper member 42 and the lower member 43 are separated from each other due to the deformation of the partition plate 44.
　一方、上述した本発明の第１実施例においては、図１０に示すように、例えば吸気マニホールド１内の吸気圧の影響によって、整流板１１が一端側の挟持部１４ａから他端側の挟持部１４ｂに向かう間でアッパ部材２側に向かって凸（図１０における上方側に向かって凸）となるように変形すると、凹凸係合部１５において凸部１６の内側面１６ａと凹部１７の内側面１７ａとが面接触し、整流板１１の変形が抑制される。 On the other hand, in the first embodiment of the present invention described above, as shown in FIG. 10, for example, due to the influence of the intake pressure in the intake manifold 1, the rectifying plate 11 is changed from the holding portion 14a on one end side to the holding portion on the other end side. 14b, the inner surface 16a of the convex portion 16 and the inner surface of the concave portion 17 in the concave-convex engaging portion 15 are deformed so as to be convex toward the upper member 2 side (convex upward in FIG. 10). 17a is in surface contact and the deformation of the rectifying plate 11 is suppressed.
　また、図１１に示すように、例えば吸気マニホールド１内の吸気圧の影響によって、整流板１１が一端側の挟持部１４ａから他端側の挟持部１４ｂに向かう間でロア部材３側に向かって凸（図１１における下方側に向かって凸）となるように変形すると、凹凸係合部１５において凸部１６の外側面１６ｂと凹部１７の外側面１７ｂとが面接触し、整流板１１の変形が抑制される。 As shown in FIG. 11, for example, due to the influence of the intake pressure in the intake manifold 1, the rectifying plate 11 is directed toward the lower member 3 while the rectifying plate 11 is directed from the clamping portion 14 a on one end side to the clamping portion 14 b on the other end side. When deformed so as to be convex (convex downward in FIG. 11), the outer surface 16 b of the convex portion 16 and the outer surface 17 b of the concave portion 17 are in surface contact with each other in the concave and convex engaging portion 15, and Is suppressed.
　すなわち、整流板１１とロア部材３との間に凹凸係合部１５を設けることによって、整流板１１の変形を抑制することができる。つまり、第１実施例の溶着面４においては、整流板１１の変形に起因してアッパ部材２とロア部材３とを離間させる方向に作用する応力を相対的に低減することができる。そのため、溶着面４の耐圧性が相対的に向上することになり、吸気マニホールド１の肉厚を相対的に薄肉にしても所望の耐圧性を確保することが可能となるので、総じて吸気マニホールド１の軽量化を図ることができる。 That is, by providing the concavo-convex engaging portion 15 between the rectifying plate 11 and the lower member 3, deformation of the rectifying plate 11 can be suppressed. That is, on the welding surface 4 of the first embodiment, the stress acting in the direction of separating the upper member 2 and the lower member 3 due to the deformation of the rectifying plate 11 can be relatively reduced. Therefore, the pressure resistance of the welding surface 4 is relatively improved, and it is possible to ensure the desired pressure resistance even if the thickness of the intake manifold 1 is relatively thin. Can be reduced in weight.
　また、上述した第１実施例の凹凸係合部１５は、整流板１１側に凸部１６が形成され、ロア部材３側に凹部１７が形成されているが、図１２～図１５に示す第２実施例のように、整流板１１側に凹部１７に相当する貫通穴部３１を形成し、ロア部材３側に凸部１６に相当する凸部３２を形成してもよい。以下、本発明の第２実施例について説明するが、上述した第１実施例と同一の構成要素については同一の符号を付し、重複する説明を省略する。 Further, in the concave / convex engaging portion 15 of the first embodiment described above, the convex portion 16 is formed on the rectifying plate 11 side and the concave portion 17 is formed on the lower member 3 side. As in the second embodiment, the through hole 31 corresponding to the concave portion 17 may be formed on the current plate 11 side, and the convex portion 32 corresponding to the convex portion 16 may be formed on the lower member 3 side. Hereinafter, the second embodiment of the present invention will be described. However, the same components as those in the first embodiment described above are denoted by the same reference numerals, and redundant description will be omitted.
　この第２実施例では、整流板１１の挟持部１４に貫通形成された貫通穴部３１と、ロア部材３の開口縁に形成された凸部３２と、から凹凸係合部３３が構成されている。 In the second embodiment, a concave / convex engaging portion 33 is constituted by a through hole portion 31 formed through the sandwiching portion 14 of the current plate 11 and a convex portion 32 formed at the opening edge of the lower member 3.

Is formed. As shown in FIG. 15, the through hole portion 31 formed in the holding portion 14 is formed so as to be orthogonal to the welding surface 4 to which the upper member 2 and the lower member 3 are joined.
　詳述すると、凸部３２は、溶着面４に対して直交する内側面３２ａ及び外側面３２ｂを有している。これら内側面３２ａ及び外側面３２ｂは、挟持部４の幅方向（長手方向）に沿うように、ロア部材３外周縁の周方向に沿って形成されている。内側面３２ａは、外側面３２ｂよりもロア部材３の内側に位置している。一方、貫通穴部３１は、溶着面４に対して直交する内側面３１ａ及び外側面３１ｂを有している。これら内側面３１ａ及び外側面３１ｂは、挟持部１４の幅方向（長手方向）に沿って形成されている。内側面３１ａは、外側面３１ｂよりも整流板１１の内側に位置している。 Specifically, the convex portion 32 has an inner surface 32 a and an outer surface 32 b that are orthogonal to the welding surface 4. The inner side surface 32 a and the outer side surface 32 b are formed along the circumferential direction of the outer peripheral edge of the lower member 3 so as to be along the width direction (longitudinal direction) of the sandwiching portion 4. The inner side surface 32a is located inside the lower member 3 with respect to the outer side surface 32b. On the other hand, the through hole portion 31 has an inner side surface 31 a and an outer side surface 31 b that are orthogonal to the welding surface 4. The inner side surface 31 a and the outer side surface 31 b are formed along the width direction (longitudinal direction) of the sandwiching portion 14. The inner side surface 31a is located inside the current plate 11 than the outer side surface 31b.
　そして、凹凸係合部３３においては、互いに対向する凸部３２の内側面３２ａと貫通穴部３１の内側面３１ａとが係合すると共に、互いに対向する凸部３２の外側面３２ｂと貫通穴部３１の外側面３１ｂとが係合する。つまり、互いに対向する凸部３２の内側面３２ａと貫通穴部３１の内側面３１ａは、アッパ部材２とロア部材３とが接合される溶着面４に対して直交し、かつ挟持部１４の長手方向に沿った凹凸係合面となっている。また、互いに対向する凸部３２の外側面３２ｂと貫通穴部３１の外側面３１ｂも同様に、アッパ部材２とロア部材３とが接合される溶着面４に対して直交し、かつ挟持部１４の長手方向に沿った凹凸係合面となっている。 And in the uneven | corrugated engagement part 33, while the inner surface 32a of the convex part 32 and the inner surface 31a of the through-hole part 31 which mutually oppose, it engages with the outer side surface 32b and the through-hole part of the convex part 32 which mutually oppose The outer surface 31b of 31 engages. That is, the inner side surface 32a of the convex portion 32 and the inner side surface 31a of the through hole portion 31 that face each other are orthogonal to the welding surface 4 to which the upper member 2 and the lower member 3 are joined, and the length of the holding portion 14 It is an uneven engagement surface along the direction. Similarly, the outer surface 32b of the convex portion 32 and the outer surface 31b of the through hole portion 31 that face each other are also orthogonal to the welding surface 4 to which the upper member 2 and the lower member 3 are joined, and the sandwiching portion 14. It is the uneven | corrugated engagement surface along the longitudinal direction of this.
　また、凸部３２には、凸部３２の外側面３２ｂと凸部３２の先端面３２ｃとが交差する角部を斜めに切り落とした形をなす傾斜面３２ｄが形成されている。そして、貫通穴部３１の外側開口縁は、凸部３２の傾斜面３２ｄと同じ傾きの傾斜面３１ｃとなるように形成されている。そのため、凸部３１の貫通穴部３１への挿入が容易となり、整流部材１０のロア部材３への組み付け性が向上している。 Further, the convex portion 32 is formed with an inclined surface 32d that is formed by obliquely cutting off a corner portion where the outer surface 32b of the convex portion 32 and the tip surface 32c of the convex portion 32 intersect. The outer opening edge of the through hole portion 31 is formed to be an inclined surface 31c having the same inclination as the inclined surface 32d of the convex portion 32. Therefore, the insertion of the convex portion 31 into the through hole portion 31 is facilitated, and the assembling property of the rectifying member 10 to the lower member 3 is improved.
　このような第２実施例においても、整流板１１とロア部材３との間に凹凸係合部３３を設けることによって、上述した第１実施例と同様に、整流板１１の変形を抑制することができる。つまり、第２本実施例の溶着面４においても、整流板１１の変形に起因してアッパ部材２とロア部材３とを離間させる方向に作用する応力を相対的に低減することができる。そのため、上述した第１実施例と同様に、溶着面４の耐圧性が相対的に向上することになり、吸気マニホールド１の肉厚を相対的に薄肉にしても所望の耐圧性を確保することが可能となるので、総じて吸気マニホールド１の軽量化を図ることができる。 Also in the second embodiment, by providing the concave and convex engaging portion 33 between the rectifying plate 11 and the lower member 3, the deformation of the rectifying plate 11 is suppressed as in the first embodiment described above. Can do. That is, also on the welding surface 4 of the second embodiment, it is possible to relatively reduce the stress acting in the direction of separating the upper member 2 and the lower member 3 due to the deformation of the rectifying plate 11. Therefore, similarly to the first embodiment described above, the pressure resistance of the welding surface 4 is relatively improved, and the desired pressure resistance is ensured even if the thickness of the intake manifold 1 is relatively thin. Therefore, the weight of the intake manifold 1 can be reduced as a whole.
　また、第２実施例おいては、挟持部１４に貫通穴部３１が形成されているが、貫通穴部３１に換えて、ロア部材３側の凸部３２と係合可能な凹部を形成するようにしてもよい。 In the second embodiment, the through-hole portion 31 is formed in the clamping portion 14, but instead of the through-hole portion 31, a concave portion that can be engaged with the convex portion 32 on the lower member 3 side is formed. You may do it.
　なお、上述した各実施例において、凹凸係合部１５、３３は、挟持部１４の全幅よりも短くなるように設定されているが、挟持部１４の全幅に亙って凹凸係合部１５、３３を形成するようにしてもよい。 In each of the above-described embodiments, the concave and convex engaging portions 15 and 33 are set to be shorter than the entire width of the sandwiching portion 14.
