。[Claims for Utility Model Registration] It has a plurality of pairs of guide rails that support a plurality of printed wiring boards in parallel with a predetermined interval, and
It has an air intake port that takes in outside air on one end surface, and an air exhaust port that exhausts inside air on the opposite end side, and the air flows between the plurality of printed circuit boards mounted on the housing via each of the guide rails. In a printed wiring board shelf box structure that cools the inside of the housing by discharging internal air from the air outlet and taking in outside cold air from the air intake port, the printed wiring board is attached to an adjacent guide rail. A shielding plate is attached along one end side of the air intake port side of the printed wiring board to shield the flow path so that air does not flow between the printed wiring board and the guide rail if the printed wiring board is not mounted. Printed wiring board shelf box structure.
