The invention provides a rodent housing rack that effectively draws the air inside the cages out through exhaust vents. The rodent housing rack comprises: a rack with multiple shelves 2 in which a plurality of cages 3 are arranged and stored, and where the shelves 2 are formed from shelf panels 4; cages 3 that are box-shaped containers having a rectangular-shaped opening that opens up the entire top surface; and an exhaust chamber located on the rear surface of the shelves 2 and that connects all of the shelves 2; and wherein negative pressure occurs inside the shelves 2 and causes air to flow in one-way from the front of the shelves 2 toward the rear; and wherein the space between the opening surface on the top of the cage 3 and the bottom surface of the shelf panel 4 above it is closed off by hanger partitions 5 that close off the top on the left and right sides of the cage and a back panel that comes in contact with the rear of the cage, such that only the front side of the space is open; and exhaust vents 9 are formed in the back panel such that the space above the cage is connected to the exhaust chamber through the vents.
