PROBLEM TO BE SOLVED: To provide an outdoor installation base station equipment equipped with a louver in which the degree of opening/closing is controlled appropriately depending on the outer air temperature. SOLUTION: The outdoor installation base station equipment comprises a means for detecting the outer air temperature of the equipment, a number of revolution control fan 4 generating wind for cooling a cooling object by taking the outer air into the equipment and varying the number of revolutions depending on the detection results from the outer air temperature detecting means, and a wind pressure opening/closing louver 6a installed at an exhaust port 6 for discharging the cooling wind to the outside of the equipment and varying the opening/closing amount depending on the wind pressure of cooling wind.
