Summary:PROBLEM TO BE SOLVED: To provide a fan-fitting structure capable of smoothing the air flow and increasing the cooling efficiency, and reducing the noise. SOLUTION: This structure is constituted by fixing a board 1a for mounting heat-generating parts on, etc., to the inside of a box-shaped chassis 2 having a plurality of air holes 2a, covering the chassis 2 with a box 3 having air outlets 3b and air inlets 3a, causing the chassis 2 to have an air hole 2b corresponding to the air outlets 3b, fixing a fitting frame 4 projecting outside to the periphery of the air hole 2b, and fitting an axial fan 5 to the fitting frame 4. In this case, the fitting frame 4 projects into the shape of a trapezoid, and air in the chassis 2 is sucked into the axial fan 5 through this fitting frame 4 from the air hole 2b, so that no eddies are generated. Accordingly, it is possible to increase cooling efficiency, and to reduce the noise.
