PURPOSE:To prevent a vibration of a fan motor and a core oscillation of a rotating shaft by a method wherein a vibration-proof member is fixed between a leg piece of a fixing member extending toward an axis of rotating shaft of the fan motor and an outer peripheral wall of the fan motor. CONSTITUTION:After a fan motor 11 having a cylindrical rubber 14 abutted against both side surfaces 16 and 17 is held by fixing members 12 and 13, a flange piece 21 of the fan motor 11 is placed along the first groove 21 of a vibration-proof member 20 from between a short piece 19 and a long piece 22 of a fixing member 13, and then the vibration-proof member 20 is fixed between an outer peripheral wall 24 of the fan motor 11 and the long (leg piece) piece 22. After this operation, this long piece 22 is fixed to a fixing plate 10. In this way, a space between an outer peripheral wall 24 and the long piece 22 is resiliently held by the vibration-proof material 20, respectively. Accordingly, a normal vibration when the fan motor 11 is operated is absorbed by the cylindrical rubber 14 and in turn even if the fan motor 11 itself moves toward the rotating direction of the rotary shaft 15 when the operation is started or at a high speed rotation, its movement is restricted by the vibration-proof rubber 20. |
