ルが塞がれてしまうという問題点があつた。 However, when a reinforcing cylinder is formed using a punched plate in this way, the punched band plate is shaped into a cylinder and spot welded, which complicates the number of man-hours, significantly reduces productivity, and increases costs. I am forced to do so. Also, burrs that occur when punching, etc.
Dust such as spatter that adheres during spot welding may peel off during use and get mixed into the fluid, causing various problems.For example, when used as a fuel filter, the fuel nozzle may be blocked by the burrs, spatter, etc. There was a problem that it would get lost.

もにごみの発生を防止することができる。<<Means and operations for solving the problem>> In order to achieve the above object, the reinforcing cylinder of the filter element of the present invention is formed into a cylindrical shape from synthetic resin, and the reinforcing cylinder of the filter element of the present invention is made of synthetic resin, and has a uniform direction around the entire circumference of the cylindrical body. A large number of oriented communicating holes including tangential portions are formed, and the communicating holes communicate between the inside and outside of the cylindrical body, and the reinforcing tube is formed in a single die-cutting process. This makes it possible to improve productivity and prevent the generation of waste.
≪実施例≫

０ａ形成が可能となる。 That is, FIG. 1 shows a reinforcing tube 12 of a filter element 10 showing an embodiment of the present invention, and this reinforcing tube 12 is arranged on the inner periphery of a filter paper 14 formed in an annular shape. Both ends of the annular recess 1 of the upper and lower end plates 16 and 18
6a, 18a and are closed. As shown in FIGS. 2, 3, and 4, the reinforcing tube 12 is made of synthetic resin and has a cylindrical shape, and has a communication hole 20 on its entire circumference that communicates between the inside and outside of the cylindrical body. Many are formed. The communication holes 20 are formed so that their orientation directions, that is, their central axes are all in the same direction and parallel to each other, and are integrally molded using a mold 30 shown in FIG. 5. This mold 20 includes an inner mold 32 that forms the inner space of the reinforcing tube 12.
and left and right outer molds 3 that form the outer periphery of the reinforcing tube 12.
These left and right outer molds 34,
36 is joined on the central axis of the inner mold 32. In addition, in the opposing parts of these left and right outer molds 34 and 36,
A large number of cores 38 for forming the communication holes 20 are formed in the same direction, and their tips are brought into close contact with the outside of the inner mold 32. Incidentally, among the plurality of cores 38, the cores 38a and 38b have communication holes 20 oriented in the tangential direction of the reinforcing tube 12.
The tips thereof are joined at the center of the inner mold 32 (mold dividing line), and the outside thereof is in contact with the inner mold 32 on a tangent line. Therefore, the part that touches on this tangent line becomes the communication hole 20a on the parting line of the reinforcing cylinder 12, and the elongated oval-shaped communication hole 2 at the tangent part
0a formation becomes possible.

のごみの発生がなくなる。 With the above configuration, in this embodiment, the reinforcing tube 12 is made of synthetic resin, and the communication holes 20, 20
The communication holes 20, 2 with the orientation direction of a fixed in a certain direction.
Since 0a was formed around the entire circumference including the tangential part,
The inside and outside of the reinforcing cylinder 12 can be evenly communicated, and it can be used as the reinforcing cylinder 12 for the filter element 10. Also, the communication hole 20,
By setting the orientation direction of 20a in a fixed direction,
It becomes possible to integrally mold the reinforcing cylinder 12 using the mold 30, and productivity is greatly improved. Furthermore, molding of synthetic resin eliminates the generation of dust such as burrs and spatter.
なお、本実施例は濾紙１４の内周に用いられる
補強筒１２を示したがこれに限ることなく濾紙１
４の外周に用いられる補強筒にあつても本考案を
適用することができることは勿論である。 Although this embodiment shows the reinforcing tube 12 used on the inner periphery of the filter paper 14, the reinforcing tube 12 is not limited to this.
It goes without saying that the present invention can also be applied to the reinforcing tube used on the outer periphery of No. 4.
