- the molten resin permeates into the upper end 22u and the lower end 22d of the filter element 22. Thereafter, the molten resin is hardened by natural cooling, and the upper end 22u and the lower end 22d of the filter element 22 are fixed to the upper cover 30 and the lower cover 31. At this time, the upper cover 30 and the lower cover 31 are also welded and joined to the filter case 21. As a result, the end of the filter element 22 is firmly fixed to the filter case 21 (including the upper cover 30 and the lower cover 31). In this way, the ends of the filter element 22 are fixed to the filter case 21 and the upper cover 30 and the lower cover 31 welded to the filter case 21 almost simultaneously.
- the filter frame can be made unnecessary without deteriorating the filter performance.
- the ends 22 b and 22 c of the filter element 22 are fixed to the inner wall surface of the filter case 21.
- the upper and lower ends 22u, 22d of the filter element 22 are fixed to the upper cover 30 and the lower cover 31 welded to the filter case 21.
- the end of the filter element 22 is firmly fixed to the filter case 21 and the upper and lower covers 30, 31 welded to the filter case 21. That is, in the fuel filter 6, the filter element 22 can be fixed to the filter case without passing through the filter frame.
- grooves 34 are formed at upper and lower ends of a portion where the ends 22 b and 22 c of the filter element 22 are welded to the filter case 21. As a result, excess molten resin is collected in the groove 34 and hardened there. Therefore, it is possible to reliably avoid a situation in which a part of the cured excess resin is mixed into the filtered fuel. In addition, since resin can be prevented from adhering to the heating punch 39, production efficiency does not decrease.
- a convex rib 32 is provided on the inner wall surface on the inner peripheral side of the filter case 21, and a convex rib 33 is provided on an inner wall surface on the outer peripheral side.
- a substantially C-shaped and semicircular filter device is used as an example.
- the present invention can be applied to a filter device having a substantially entire circumference.
- the present invention can be applied to an I-shaped filter device.
- the present invention is applied to a filter device for removing impurities in various fluids, without being limited to the force of applying the filter device according to the present invention to a fuel filter. can do.
- the container of the filter device is formed by combining a total of three container constituent members of the filter case 21, the upper cover 30, and the lower cover 31. It can also be configured by a combination of.
