する。The lower case 2 constructed as described above
The filter member 6 in the form of a sheet is positioned on the upper part of the lower case 2, the opening 7 is made to coincide with the suction port 3 of the lower case 2, and the welding horn 10 located above the lower case 2 is lowered.
The heating surface 11 is brought into contact with a projection 4 provided integrally with the peripheral edge of the suction port 3 of the lower case 2, and the projection 4 is melted and solidified into a shape matching the shape of the heating surface 11 of the welding horn 10.

【００１６】この場合、溶着ホーン１０の加熱面１１に

ケース２の吸込口３周縁部に固着されることになる。In this case, since the concave portion 12 having a predetermined depth is formed on the entire surface of the heating surface 11 of the welding horn 10, the projection 4 has a shape corresponding to the shape of the concave portion 12. It is melted and solidified (see FIGS. 2 and 3).
That is, the filter medium 6 is formed by the recess 12 of the welding horn 10.
On the upper surface side of the peripheral portion of the opening 7, a thickly built-up portion 5 having a curved surface over its entire periphery is integrally formed,
By this build-up portion 5, the peripheral portion of the opening 7 of the filter medium 6 is fixed to the peripheral portion of the suction port 3 of the lower case 2.

に強固に固着することができることになる。In the assembling structure 1 of the fluid filter device for an automatic transmission as described above, when the projection 4 on the peripheral edge of the suction port 3 of the lower case 2 is melted and solidified, it is formed on the heating surface 11 of the welding horn 10. Due to the concave portion 12 formed on the upper surface side of the peripheral portion of the opening 7 of the filter medium 6, the thickly built-up portion 5 having a curved surface over the entire periphery is integrally formed. Suction port 3 of lower case 2 around opening 7 of material 6
Can be firmly fixed to the substrate.

【００１９】したがって、使用時に油圧等が作用して
