Rotary decoration driving device

A rotary decoration driving device comprising:

• a case;
• a first rotary shaft having a first end portion rotatably supported by the case and a second end portion supporting a first decoration for rotation therewith;
• a second rotary shaft mounted on the first rotary shaft for rotation therewith and having an end portion supporting a second decoration for rotation therewith;
• a first gear mounted on the first rotating shaft for rotation therewith;
• a second gear mounted on the second rotating shaft for rotation therewith;
• at least one intermediate gear driven to undergo intermittent rotation during use of the rotary decoration driving device;
• transmitting means for transmitting the intermittent rotation of the intermediate gear to the first and second gears;
• and smoothing means for smoothing the intermittent rotation of the intermediate gear to thereby transmit a smooth and continuous rotary motion to the first and second gears.

• a gear mounted on the rotary shaft for rotation therewith;
• a rotary member driven to undergo intermittent rotation during use of the rotary decoration driving device;
• transmitting means for transmitting the intermittent rotation of the rotary member to the gear;
• and
• damping means for damping the intermittent rotation transmitted to the gear to thereby transmit a smooth and continuous rotary motion to the gear.
