The part to be joined (that is, between the joining protrusion and the joining step)
Since the pinching part and the pinching part (that is, between the pinching protrusion and the pinching step part) are separate, scratches and welding burrs do not occur on the pinched object such as the screen, so the performance of the pinched object does not deteriorate. Further, since the fibers or the like of the object to be sandwiched do not exist between the two parts, the bonded state is stable and the sealing performance is improved. Furthermore, the outer peripheral shape of the resin part or the outer peripheral shape of the object to be sandwiched is improved. Even if it is complicated, it is possible to reliably join the two parts while always holding the object to be pinched between the two parts. Further, since no extra parts such as a middle case and a burr prevention guide which have been conventionally used are required, work efficiency is good and it is economical.

The method for joining resin-made parts according to the present invention is a method of joining two parts made of resin, that is, one part. A pressure is applied vertically between the case 1 and the lower case 2, which is the other part, with the screen 3, which is the object to be held, made of non-woven fabric, wire mesh, filter paper or the like being sandwiched between the cases 1 and 2. At the same time, horizontal vibration is applied between the cases 1 and 2 to generate frictional heat between the cases 1 and 2 to integrally join the cases 1 and 2.

A joining protrusion 1a and a sandwiching protrusion 1b projecting downward in the drawing are integrally formed at a predetermined interval, and a joining step 2a facing the joining protrusion 1a is provided on the upper surface side of the lower case 2.
And a sandwiching stepped portion 2b facing the sandwiching protrusion 1b are continuously formed. A groove 4 is formed between the joining step portion 2a and the sandwiching step portion 2b.

In order to join the two cases 1 and 2 with the screen 3 being sandwiched between the upper case 1 and the lower case 2, first, the sandwiching projection 1b of the upper case 1 and the sandwiching step 2b of the lower case 2 are to be joined together. The peripheral portion of the bag-shaped screen 3 which is folded back in between and has a double peripheral portion is positioned, and in this state, the joint projection 1a of the upper case 1 and the joint step 2a of the lower case 2 are brought into contact with each other.

By generating frictional heat between the protrusion 1a and the joining step 2a of the lower case 2, the joining protrusion 1a of the upper case 1 is generated.
And the joining step portion 2a of the lower case 2 are integrally joined, and at this time, the screen 3 is held between the holding projection portion 1b of the upper case 1 and the holding step portion 2b of the lower case 2.

とができる。As described above, the joining portion (that is, between the joining protrusion 1a and the joining step portion 2a) and the holding portion (that is, between the holding protrusion portion 1b and the holding step portion 2b) are separately provided. By doing so, the fibers of the screen 3 are
There is no intervening between the joining projection 1a of 1 and the joining step 2a of the lower case 2, and the joining of the cases 1 and 2 is surely performed. Further, since the welding burrs can be prevented from scattering at the joining portion between the joining protrusion 1a of the upper case 1 and the joining step 2a of the lower case 2 by the holding protrusion 1b, the welding burrs can be used. The performance of the screen 3 does not deteriorate, and the screen 3 can be reliably held.

る。The crushing amount of the screen 3 clamped between the upper case 1 and the lower case 2 is determined by the clamping protrusion 1b.
The desired crushing amount can be obtained by changing the length of the sheet, and therefore the sheet-shaped screen 3 can be reliably sandwiched between the cases 1 and 2 even if the sheet-shaped screen 3 is used in a single layer or a double layer.

４の上面とに渡って位置させる。That is, in the method of joining resin parts shown in FIG. 2, the two parts made of resin, for example, the upper case 3 is used.
The upper case 31, the lower case 32, and the deburring guide 34 are integrated with each other while the screen 33 made of non-woven fabric, wire mesh, filter paper or the like is sandwiched between the 1 and the lower case 32 via the deburring guide 34. The step 33a and the step 32b are continuously provided on the lower case 32, and the screen 33 and the deburring guide 34 are provided on the lower step 32b between the lower case 32 and the deburring guide 34. 33 are sandwiched so that the upper surface of the deburring guide 34 and the step portion 32a located at the upper portion are at the same height, and the protrusion 31a of the upper case 31 is located at the upper portion of the lower case 32. Step 32a and deburring guide 3

4 and the lower case 32 are applied with a vertical pressure, and horizontal vibration is applied between the upper case 31 and the deburring guide 34 and the lower case 32.
Friction heat is generated between the upper case 31, the deburring guide 34 and the lower case 32 to integrally join the upper case 31 with the deburring guide 34 and the lower case 32.

いる。Then, in the method of joining the resin parts constructed as described above, the screen 33 is sandwiched between the upper case 31 and the lower case 32 via the deburring guide 34, and both cases 31, 32 are joined. Since the parts are joined together, the number of parts (burr prevention guide) is increased compared to the method of joining the resin parts in this embodiment, the work efficiency is poor, and the cost is high.

済的である。Therefore, when the resin part joining method according to this embodiment is used, since the screen is free from scratches, welding burrs and the like as in the conventional case, the performance of the screen is not deteriorated and the screen between the two parts is not deteriorated. Since there is no intervening fiber etc., the joined state is stable and the sealing performance is improved,
Further, even if the outer peripheral shape of the resin component or the outer peripheral shape of the screen is complicated, the two components can be reliably joined with the screen always sandwiched between the two components. In addition, since it does not require extra parts such as a middle case and a burr prevention guide that have been conventionally used, work efficiency is good and it is economical.

るという優れた効果を有するものである。As described above, according to the present invention, the portion to be joined (between the joining protrusion and the joining step portion) and the portion to be held (between the holding protrusion and the holding step portion) are provided. Since they are separate, scratches and welding burrs do not occur on the sandwiched objects such as screens, so the performance of the sandwiched objects does not deteriorate, and
Since the fibers of the object to be sandwiched do not intervene between the two parts, the joined state is stable and the sealing performance is improved, and the outer peripheral shape of the resin part and the outer peripheral shape of the object to be sandwiched are complicated. However, it is possible to reliably join the two components while the object to be sandwiched is reliably sandwiched between the two components. Further, since it does not require extra parts such as a middle case and a burr prevention guide which have been conventionally used, it has an excellent effect that work efficiency is good and it is economical.
