BACKGROUND ART Generally, an AC motor is used for opening and closing a damper installed in a freezer, an ice water purifier, an air conditioner or the like to control the flow of cold air.

The alternating-current motor includes a driving gear G1 interlocked with the rotor R, an output gear G3 outputting a rotational force, and a connecting gear G2 interlocking the driving gear G1 and the output gear G3 (See Fig. 4)

That is, the driving gear G1 is rotated by the rotation of the rotor R, whereby the connecting gear G2 rotates in conjunction with the rotation, and the rotational force is finally output through the output gear G3.

The driving gear G1, the connecting gear G2 and the output gear G3 are received by the housing H and closed by a housing cover C disposed on the upper surface of the housing H.

However, in the conventional AC motor as described above, vibration is generated by the rotation of each of the gears. To solve this problem, in the conventional AC motor, a split bushing is installed in the rotor to cancel vibration. See Japanese Utility Model No. 20-0138411)

However, even with the split bushing, the vibration can not be sufficiently canceled, and problems such as noise and durability due to vibration still occur.

On the other hand, the conventional AC motor as described above is a well-known technique and is particularly described in the following prior art documents, so that redundant description and illustration are omitted.
