Meanwhile, the inner filter cover 173 is coupled to a cylinder 173a having a lower opening at the center of the rectangular plate 173b, and the upper surface of the cylinder has a through hole.

An inner filter plate (176) having a through hole vertically penetrating is coupled to the opening of the cylinder.

A plurality of inner filter seating projections 178 are formed on the circumferential surface of the inner filter tube plate 176 at predetermined intervals so as to be spaced apart from each other with a predetermined distance therebetween. An inner surface 173a of the cylinder 173 facing the inner filter seating projection 178 An inner filter receiving groove 175 is formed.

In addition, the inlet side of the inner filter receiving groove 175, into which the inner filter receiving projection 178 is inserted, is formed to have a width equal to that of the inner filter receiving projection 178, And the groove is formed to extend.

After the inner filter seating protrusions 178 are inserted into the inner filter seating grooves 175 and then the inner filter seating protrusions 178 are tightly adhered to a predetermined depth, the inner filter seating holes 176 are formed along the inner circumferential surface of the cylinder, When they are rotated, they are firmly connected to each other.

An inner filter cylinder plate knob 177 is formed on the lower surface of the inner filter cylinder plate 176 for rotation of the inner filter cylinder plate 176.

The release of the inner filter tub plate 176 and the inner filter cover 173 may be performed in the reverse order of the above-described process.

In the inner space of the cylinder, an appropriate kind of filter is placed as described above, if necessary.

As a result, the contaminated air in the body 110 is discharged to the outside through the exhaust port 190 through the through hole formed in the upper surface of the filter, the filter, and the inner filter tube plate 176.

FIG. 16 is a perspective view of a cover in which a top filter of an animal culture cage of the present invention is detached, FIG. 17 is a perspective view showing a top filter plate of the top filter of the present invention, and FIG. Ring perspective.

A top filter receiving groove 162 having the same shape as the above-described inner filter receiving groove 175 is formed on the inner surface of the top filter groove 161.

The top filter cover 164 is fastened to the opening of the top filter groove 161. The top filter cover 165 has the same shape as the inner filter vent plate 176 described above.

Therefore, the process of fastening the top filter cover 164 to the top filter groove 161 can be carried out in the same manner as the fastening process in the inner filter 170 by fixing the top filter seating projection 166 formed on the top filter cover 164 to the top filter seating groove 166. [ (162).

In addition, the top filter cover 164 is also formed with a top filter knob 165 as shown in Fig. 17 for ease of rotation.

On the other hand, when the highly pathogenic animal is cultivated between the top filter cover 164 and the top filter communicating plate 163, the sealing plate 167 is configured as shown in FIG. 18 so that no air can pass through the cage at all.

The sealing plate 167 is freely detachable according to the nature of the animal being cultured.
