間に上下方向から圧力を加えて両ケース１，２間を一体
に接合するものである。That is, the method for joining resin parts shown in this example is as follows:
A strainer 3 made of nonwoven fabric, wire mesh, etc. is sandwiched between two parts made of resin, for example, an upper case 1 and a lower case 2, with a burr preventing guide 4 interposed therebetween. horizontal vibration is applied to generate frictional heat between both cases 1 and 2, and furthermore, both cases 1 and 2 are
Both cases 1 and 2 are joined together by applying pressure from above and below between them.
この場合、前記上ケース１の下面中央部には、図中下方

れるようになっている。In this case, a protrusion 8 projecting downward in the figure is integrally formed at the center of the lower surface of the upper case 1, and two step portions 9 and 10 are formed on the upper surface of the lower case 2. Both cases 1 and 2 are formed continuously, and the upper step 9 in the figure has both cases 1 and 2.
The protrusion 8 of the upper case 1 comes into contact with the upper case 1 when they are joined, and the peripheral edge of the strainer 3 is provided on the lower step 10 in the figure via the burr prevention guide 4. It has become.
前記バリ止めガイド４の両端部には、図中下方に屈曲す

上方に屈曲するバリ発生防止用の突部６がそれぞれ設け
られている。At both ends of the burr prevention guide 4, there are provided a protrusion 5 for adjusting the amount of crushing of the strainer 3, which bends downward in the figure, and a protrusion 6, which bends upward in the figure, for preventing burr generation. .
前記両ケース１．２間に設けられる前記ストレーナ３は
、シート状物のものをそのまま両ケース１．２間に設け
たり、あるいは、折り重ねて袋状にして両ケース１．２
間に設けたりするようになっている。The strainer 3 provided between the two cases 1.2 can be a sheet-like strainer that is directly provided between the two cases 1.2, or can be folded up into a bag shape and placed between the two cases 1.2.
It is designed to be placed in between.
そして、上記のように構成した上ケース１、下ケース２
の間に、バリ止めガイド４を介してストレーナ３を挟持
するには、まず、下ケース２の下側の段部１０内に前記
バリ止めガイド４を介して折り返して周縁部を二重にし
て袋状にしたストレーナ３を位置させる。Then, upper case 1 and lower case 2 configured as above
In order to sandwich the strainer 3 through the anti-burr guide 4 during the process, first, fold the strainer 3 through the anti-burr guide 4 into the lower step part 10 of the lower case 2 so that the peripheral edge is doubled. A bag-shaped strainer 3 is positioned.
この場合、バリ止めガイド４の下方に屈曲する突部５の
外周面側が下ケース２の下側の段部１０の側面に、内周
面側がストレーナ３の外周縁部に接触するようにすると
ともに、バリ止めガイド４の下面側がストレーナ３の上
面に接触するようにする。In this case, the outer peripheral surface side of the downwardly bent protrusion 5 of the burr prevention guide 4 should be in contact with the side surface of the lower step part 10 of the lower case 2, and the inner peripheral surface side should be in contact with the outer peripheral edge of the strainer 3. , so that the lower surface side of the burr prevention guide 4 comes into contact with the upper surface of the strainer 3.
このようにして、下ケース２の下側の段部１０内にバリ

の間で凹部１１が形成され、この凹部１１によって振動
時におけるストロークが調整されるようになっている。In this way, by positioning the strainer 3 in the lower step 10 of the lower case 2 via the burr prevention guide 4, the upper step 9 of the lower case 2 and the strainer 3 are placed on the upper surface of the lower case 2. A recess 11 is formed between the burr prevention guide 4 and the upwardly bent protrusion 6, and the recess 11 allows the stroke during vibration to be adjusted.
次に、前記下ケース２の上側の段部９に前記上ケース１

止めガイド４を介してストレーナ３が挟持されることと
なる。Next, the upper case 1 is attached to the upper step 9 of the lower case 2.
The protrusions 8 on the lower surfaces are brought into contact with each other, and in this state horizontal vibration is applied between the upper case 1 and the lower case 2 to generate frictional heat between the two cases 1 and 2.
By applying pressure from above and below between the lower case 2 and the lower case 2, and applying vibration and pressure in this way, both cases 1
．． As shown in FIG. 2, the cases 1 and 2 are integrally joined along the shape of the recess 11, and the strainer 3 is sandwiched between both cases 1 and 2 via a burr prevention guide 4.
この場合、前記ストレーナ３はその上面、外周縁部がバ
リ止めガイド４によって保護されているので、両ケース
１．２間に振動を加える際においても、両ケース１．２
と相対的に摺動して繊維が離脱したり、バリ等が発生し
たりすることは完全に阻止できるものである。In this case, since the upper surface and outer peripheral edge of the strainer 3 are protected by the burr prevention guide 4, even when applying vibration between both cases 1.2,
It is possible to completely prevent fibers from coming off due to sliding relative to each other, and burrs from occurring.
また、両ケース１．２間の加圧時におけるストレーナ３

この長さを変えることによって所望の潰れ量が得られる
ものであり、したがって、シート状物のストレーナ３を
一重又は二重にして使用しても確実に両ケース１．２間
に挟持できるものである。In addition, strainer 3 when pressurizing between both cases 1 and 2
Since the amount of collapse can be adjusted by the length of the projection 5 for adjusting the amount of collapse of the burr prevention guide 4,
By changing this length, the desired amount of crushing can be obtained. Therefore, even if the sheet-like strainer 3 is used in a single or double layer, it can be reliably held between the two cases 1 and 2. be.
さらに、前記両ケース１．２間の溶着代Ａは前記上ケー
ス１の下面中央部に設けられている突部８の突出長さに
よって調整可能となっているので、この突出長さを変え
ることによって、両ケース１．２間の接合強さを調整で
きるものであり、したがって、両ケース１．２の接合部
の形状に影響されることなく、常に完全な接合状態が得
られるものである。Further, since the welding margin A between the two cases 1 and 2 can be adjusted by the protrusion length of the protrusion 8 provided at the center of the lower surface of the upper case 1, it is possible to adjust the protrusion length by changing the protrusion length. Accordingly, the strength of the bond between both cases 1.2 can be adjusted, and therefore a perfect bonded state can always be obtained without being affected by the shape of the bonded portion of both cases 1.2.
したがって、この実施例による樹脂製部品の接合方法を
用いれば、従来のように、ストレーナに傷やバリ等が発
生してストレーナの性能が低下してしまったり、二部品

影響されることなく、常に二部品間にストレーナを確実
