<P>PROBLEM TO BE SOLVED: To provide an animal-rearing chamber capable of reducing the amounts of air supply and exhaust, while maintaining the cleanliness in the chamber and performing the sufficient control of pressure. Ž<P>SOLUTION: The animal-rearing chamber 10 is characterized by equipping an air-supplying means 20 for introducing outer atmosphere controlled with its temperature and humidity into the chamber installing animal-rearing racks 40, an air-exhaust means 30 for exhausting the air at the animal-rearing racks 40 and in the chamber to the outside of the chamber, an air-cleaning unit 50 for sucking and cleaning the part of the air in the chamber and exhausting it into the chamber for circulating the air, a pressure sensor 60 for detecting the pressure in the chamber, and a controlling means 70 for controlling the air-supplying amount of the air-supplying means 20 and the air-exhausting amount of the air-exhausting means 30 based on the measured value of the pressure sensor 60 and maintaining the pressure of the chamber at a set value predetermined in advance.
