First, a first embodiment according to the present invention will be described. FIG. 1 is a perspective view showing a state of a single component before the filter is assembled. In the figure, reference numeral 1 is a filter, and the developed shape is a fan shape so that the outer shape is a conical shape when assembled. Further, the surface thereof is provided with a large number of holes 2 having a required size and shape according to the size of a foreign substance which is desired to prevent intrusion, and the number of perforations is determined according to the suction amount of fluid. Further, the filter 1 has a hook portion 3 projectingly provided on one side and isassembled to the hook portion 3.
A notch hole 6 is provided in theoverlapping surfaces to separate the window 4 and the window frame 5. The shape and dimensions of the hook portion 3 are formed so as to match the window 4 and the cutout hole 6. Further, the window 4, a window frame 5, the notch holes 6, after assembly, in that portion18
The same shape and the same size are also provided at positions facing each other by0 ° .
