A small animal rearing apparatus ( ) has a frame ( ) of a rectangular shape, a rearing unit having a plurality of rearing sections ( ) formed in vertical arrangement and provided respectively with floor boards ( ) sloping down toward the front. Spray nozzles ( ) are disposed respectively above the high rear ends of the floor boards ( ) to spray washing water from the high rear ends of the floor boards ( ) toward the low front ends of the same along the upper surfaces of the same, respectively. The high rear end of the floor board ( ) of each rearing division ( ) underlying the spray nozzle ( ) does not have any raised part. The spray nozzle ( ) can be disposed with its axis extended substantially in parallel to the upper surface of the floor board ( ). A downward rear rim ( ) is formed by bending downward a rear edge portion of each floor board ( ). The floor board ( ) can be detachably supported and held in place on beams ( ) of a floor board support frame with the downward rear rim ( ) engaged with the rear longitudinal beam ( ).

Small animal rearing apparatus

An air supply/exhaust device to be joined to a box-shaped rearing cage included in an experimental animal rearing apparatus to supply or exhaust air into or from the rearing cage. The air supply/exhaust device comprises an air supply pipe having a front end section provided with air supply/exhaust holes, and a stop ring mounted on a section of the air supply pipe behind the front end section provided with the air supply/exhaust holes. An elastic plug is mounted on a section of the air supply pipe extending behind the stop ring so as to be in contact with a back surface of the stop ring. The elastic plug has the shape of a truncated cone tapered toward an extremity of the air supply/exhaust pipe, and a spring holder is provided on the air supply pipe, and an elastic pressing member is mounted on a section of the air supply pipe between the elastic plug and the spring holder to press the elastic plug continuously toward the stop ring. When the air supply/exhaust device is connected to a box-shaped rearing cage, the elastic plug is inserted through an opening formed in the rear end wall of an upper cage included in a box-shaped rearing box into the upper cage and engages firmly with the edge of the opening to seal the box-shaped rearing cage.
