Abstract
A rotary decoration driving device comprises 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 is mounted on the first rotary shaft for rotation therewith and has an end portion supporting a second decoration for rotation therewith. A first gear is mounted on the first rotating shaft for rotation therewith, and a second gear is mounted on the second rotating shaft for rotation therewith. At least one intermediate gear is driven to undergo intermittent rotation. A transmitting device transmits the intermittent rotation of the intermediate gear to the first and second gears. A smoothing device smoothens the intermittent rotation of the intermediate gear to thereby transmit a smooth and continuous rotary motion to the first and second gears.
