Abstract: PROBLEM TO BE SOLVED: To measure the degree of vacuum or the like of a fan easily by simply exchanging the fan by measuring the degree of vacuum for the intake air and the air in a case means and then comparing the difference. SOLUTION: A case means 30 is separated from a protective means 70 and the shaft 2 of a power generating means 1 is projected from the case means 30 before mounting a fan 4 on the shaft 2. The protective means 70 is then mounted on the case means 30 and power is applied to the power generating means 1 while protecting the fan 4 against damage to generate a rotating power. Consequently, the shaft 2 is turned to cause rotation of the fan 4 and the air is sucked through a suction hole 71 made in the protective means 70. Degree of vacuum of the suction hole 71 is measured at that moment by a degree of vacuum measuring means 5.
