The cross-sectional shape is engaged with the substantially F-shaped locking groove, whereby the flow path 20 is formed.
The upward movement of the main body 110 in FIG. 8 can be reliably restricted by the pressing force of the fluid flowing through the main body 110. Of course, the elastic piece 15 formed on the outer peripheral side of the main body 110 also comes into close contact with the inner wall 21 of the flow path 20 and slides so that no gap is formed between the elastic piece 15 and the inner wall 21. This sliding contact force is applied to the substantially concave groove 15 b formed on the outer peripheral side of the main body 110.
Is maintained against the flow velocity by the action of the locking piece 182, so that the main body 110 can be surely prevented from coming off accidentally in combination with the action of the locking piece 182.

In 10, the fluid flowing through the flow path 20 is first filtered by the mesh 13 expanded in the mesh mounting hole 12, and then the mesh 1 expanded in the fluid flow hole 114.
Since it is filtered again through 30 and flows to the other flow path 22, the filtration of the fluid can be performed twice with one component. In this case, by forming the mesh 130 finer than the mesh 130 that performs the second filtration, it is possible to realize cleaner filtration.

効果が得られる。The bullet portion 15 has a substantially concave groove 15b with an upward opening formed between the outer peripheral edge of the main body 11 and the bullet portion 15.
5 is formed so as to bend in the diameter direction of the main body 11,
The height dimension D1 of the free end 15a is the height dimension of the upper surface 11a of the main body 11 in which the mesh mounting holes 12 are formed. By forming the height 15a lower than the upper surface 11a of the main body 11, it is possible to easily perform mold matching during manufacturing. Further, by forming the groove 15b not on the flow direction of the fluid but on the surface side opposite to the flow direction, even if the fluid filter 10 is pressed by the fluid, the reed portion 1
There is no fear that the elastic member 5 will be deformed inward by the flow velocity, and the elastic contact frictional force of the bullet piece portion 15 against the inner wall 21 does not change.
