PROBLEM TO BE SOLVED: To efficiently absorb vibration in all directions, regardless of axial direction or rotation direction. SOLUTION: A bolt 4 is fixed in an axis hole 3a provided so as to be offset from each leg mount hole 5a of a fan motor 5 provided on the top surface of a body case 1, and a base part 6a of a vibration-proofing member 6 formed of a rubber and a washer 7 are fitted onto the bolt 4 and fixed by means of a fastener, and the hole 5a of the motor 5 is fixed to a fan motor holder 6b horizontally extending from the base part of the member 6 to hold the motor 5. As a result, vibration of the fan motor in the rotation direction thereof can be absorbed by the expansion and contraction of the vibration-proofing member and vibration of the motor in the axial direction can be absorbed by the deflection of the member, so that vibration in all directions, in axial or rotation direction, can be efficiently absorbed. |
