end. The technical field to which the invention described in the claims belongs.;The present invention can cover the upper body to cover the lower body while immersing the reticular body for separating and partitioning the upper and lower bodies of the cage of the upper and lower ablation structure, while maintaining airtightness and fixing the filter at the top of the upper body with a clip-type fixing net. The purpose of this is to provide a cage that is easy to use as well as increasing the performance of filtering.;I. The technical problem the invention is trying to solve.;In a conventional cage, the upper / lower body is separated into a reticular body, but the reticular body is installed inside the lower body, and the upper body is simply covered on the outside of the lower body so that the mouse is grown in the space of the lower body or The reticulum is lifted by the let, causing the animal to escape.;In addition, since the air circulation filter of the upper / lower body separated from the outside is fixed to the inside of the upper body by a fixing frame, the upper / lower body must be separated for the replacement of the filter, which may cause bacterial infection of the animal.;All. The gist of the solution of the invention.;The reticle body 6 for separating and separating the upper and lower bodies 2 and 4 from the lower body 4 of the cage, which is made of a transparent material and is attached to the upper and lower parts, is hung to be fixed while immersing the outer periphery of the lower body 4. The upper body 2, which forms the wing 8 and is covered with the upper portion of the lower body 4, forms the recessed groove 10 so as to be covered with the lower body while the locking blade 8 is inserted therein, and the upper body The upper outside of (2) is to fix the filter 14 with a clip-type fixing net 16 so that it can be replaced without the separation of the upper / lower body when replacing the filter.;la. Important uses of the devise;Top cage for cattle animals.
