PROBLEM TO BE SOLVED: To improve installation work efficiency of a fan by easily installing the fan in a fan installing structure. SOLUTION: Positioning machine screws 4a and 4b are threadedly engaged with chassis side installation holes 22b and 22c, and these tips are projected from a chassis 2. The fan 1 is positioned so that fan side installation holes 19a and 19d are joined to chassis side installation holes 22a and 22d by inserting the tip of the positioning machine screws 4a and 4b into fan side installation holes 19b and 19c. Fixing machine screws 3a and 3b are penetrated through the fan side installation holes 19a and 19d, and are also threadedly engaged with the chassis side installation holes 22a and 22d, and thus, the fan 1 is fixed to and installed in the chassis 2. A tip part of the positioning machine screws 4a and 4b projected from the chassis 2 can be sufficiently heightened, and thus, the fan is stably positioned, and the installation work efficiency of the fan is improved.
