である。The filter 1 includes a mesh 2 and a frame 3 as filter media.
It consists of: The frame 3 is composed of a holding part 3a and a connecting part 3b. The holding portion 3a maintains the mesh 2 in a swollen bag-like state. Also, the connection part 3b
The pipe, the pump'! Connected to member P*, mesh 2
The liquid inside the mesh 2 is made to flow to the outside of the mesh 2 (or the liquid outside the mesh 2 is made to flow to the inside of the mesh 2).
このようにメツシュ２及び７レーム３を備えたタイプの
フィルタ１を製造する場合、メツシュ２とフレーム３と
を接合するには、次の２つの方法が用いられていた。When manufacturing the filter 1 having the mesh 2 and seven frames 3 as described above, the following two methods have been used to join the mesh 2 and the frame 3.
一つは、フレームを成形する型の中にメツシュの一部を
予め配置しておき、次にフレームを射出成形するもので
ある。これによると、フレーム内にメッシ１の一部が挿
入された状態で両者が接合される。One method is to place a portion of the mesh in advance in a mold for forming the frame, and then injection mold the frame. According to this, the two are joined with a part of the mesh 1 inserted into the frame.
前記第３図（イ）のフィルタ１は、この方法により製造

る。The filter 1 shown in FIG. 3(A) is manufactured by this method. A part 4 of the mesh 2 is placed in a mold (not shown) for molding the connection portion 3b of the seven-frame 3, and then the connection gIS 3b is injection molded. Then,
As shown in FIG. 3(B), a portion 4 of the mesh 2 is inserted into the connecting portion 3b and then joined. After that, the holding part 3a of the separately molded frame 3 is connected to the connecting part 3b.
Furthermore, the periphery 5 of the mesh 2 is fixed in the shape of a bag.
他の方法は、第４図（イ）（ロ）に示されているように

ム３とメ・ンシュ２を接合するものである。Another method is to insert the mesh 2 between the frame 3 and the fixing member 6 and fix it by an appropriate means such as adhesive or pressure bonding, as shown in FIGS. 4(a) and 4(b). , which connects the frame 3 and the mesh 2.
（発明が解決しようとする問題点）
しかし、上述した従来方法には、次のような問題点があ
った。(Problems to be Solved by the Invention) However, the above-mentioned conventional method has the following problems.
まず、１３図（イ）、（ロ）に示すような、フレーム３

ーム３の形状に制約を受け、形状如何によってはこの方
法の実施ができない。That is, depending on the shape of the frame 3, it is impossible to divide the frame 3 into upper and lower parts with the part 4 of the mesh 2 inserted into the frame 3. Therefore, there are restrictions on the shape of the frame 3, and depending on the shape, this method cannot be implemented.
又、メツシュ２とフレーム３を固定部材６により挟み込

タ１の信頼性、耐久性が悪くなる問題があった。Further, in the method of sandwiching the mesh 2 and frame 3 between the fixing member 6, there is a risk that the frame 3, the fixing member 6, or the filter 2 will swell and deform during use of the filter 1, and the sealing performance of the sandwiched portion may be impaired. For this reason, there was a problem that the reliability and durability of the filter 1 deteriorated.
本発明は、上記従来方法の間開に鑑みなされたものであ
る。The present invention has been made in view of the shortcomings of the above-mentioned conventional methods.
本発明の目的は、複雑な形状のフィルタでもフレームと

間にメツシュを挟んで重合し、該重合部分を超音波溶着
して構成されている。That is, in the present invention, the connection part and the holding part made of synthetic resin constituting the frame are separately injection molded, a mesh is sandwiched between the connection part and the holding part, and the mesh is polymerized, and the polymerized part is ultrasonically welded. It is configured as follows.
（実施例）
以下に、本発明の一実施例をｆ５１図及び第２図（イ）
（ロ）に基づいて説明する。(Example) An example of the present invention is shown below in Figure f51 and Figure 2 (A).
The explanation will be based on (b).

続ｇ３ａを囲むように環状に超音波溶着する。The lower end of the connecting part 3b is passed through the through hole 18 of the first mesh 3a and the mounting hole 11 of the holding part 3a, and the second joining surface 15 of the connecting part 3b and the first joining surface 13 of the holding part 3a are connected. The first mesh 3a is sandwiched between them. And fIS
Before joining 13, PA 1 (n/sh 3 a and c/WrJ2) joint surfaces 15 overlap and the overlapping portion 18 is ultrasonically welded in a ring shape so as to surround the connection g3a.

なる。Since the 7-frame frame 6 and the Pt51 mesh 3a are joined by ultrasonic welding, the sealing performance of the joint portion 18 is good.
次に、第２のメツシュ２ｂを保持部３ａめ下方から覆う
ようにし、両者の外周４を接合し、袋状とする。Next, the second mesh 2b is made to cover the holding part 3a from below, and the outer circumferences 4 of both are joined to form a bag shape.
尚、本発明は、上記の実施例に限定されるものでない。Note that the present invention is not limited to the above embodiments.

のである。Also, the mesh does not have to be one that joins two sheets,
It may be made of a single piece of mesh.1゜(Effects of the Invention) In the present invention, the connecting part and the holding part made of synthetic resin constituting the frame are separately injection molded, and a mesh is made between the connecting part and the holding part. The polymerized portion is then welded using ultrasonic waves.
