Claims

[Scope of Claim for Utility Model Registration] (1) A breeding room 1 which is divided into a work room 5 and a rack room 6 by a partition plate 3 hanging from the ceiling 2 and a sliding door 4, and a ceiling 2a of the work room 5. Air supply duct 7
an air supply hole 8 provided to supply clean air through the rack room 6; and an exhaust hole 9 provided in the ceiling 2b of the rack room 6 to discharge the air circulating in the rearing room 1 through the exhaust duct 10. and a required number of shelves 11 installed at predetermined intervals in the rack chamber 6.
and a shelf 11 of the rack 12.
A cage 13 disposed above, two parallel slide rails 14 laid on the front edges of the upper and lower racks in order to allow the sliding door 4 to slide freely in a sliding manner, and A laboratory animal characterized by comprising an opening 15 bored in each of the sliding doors 4 and an airflow retaining plate 16 attached to the rack room side of the sliding door 4 so as to cover the opening 15 and be movable to open and close at the upper side. Automatic airflow adjustment device for the breeding room. (2) A front sliding door 4a guided by at least the slide rail 14a on the work room 5 side of the sliding door 4;
The airflow retaining plate 16a attached to the airflow retaining plate 16a is cut in such a manner that the width between both sides 18 thereof becomes narrower from the upper side to the lower side. Automatic room airflow adjustment device.
