PROBLEM TO BE SOLVED: To provide a means for reducing the vibration in particular to the centrifugal force working on a fan, concerning an air conditioner indoor unit structure. SOLUTION: It becomes possible to reduce vibration even if the centrifugal force by unbalance works on a fan, by conforming the natural frequency of a vibration system, where a casing and mounted parts act as mass and a suspension rod as a spring, to the natural frequency of the vibration system where a fan and a motor act as mass and vibrationproof rubber as a spring, and also by setting this the same as the frequency corresponding to the rotational speed at operation. |
