Transmission mechanism for music box ornament
 A transmission mechanism for a music box having a plurality of ornaments coupled thereon includes a driving mechanism having a rotary wheel with an eccentric rod and disposed in the music box, a first support mounted in the music box and having a through hole, a connection rod having two opposite ends, a first elongated support member inserted through the through hole of the first support, secured on the first support and having one end coupled with an ornament and the other end secured on one end of the connection rod, a coupler having a first end connected with the other end of the connection rod and a second end coupled with the eccentric rod. Preferably, the transmission mechanism further includes a second support mounted in the music box and having a through hole, a following piece slidably moving along two opposite elongated sides of the second support, and a second elongated support member inserted through the through hole of the second support and having one end coupled with another ornament and the other end secured to the following piece. When the rotary wheel is rotated, the following piece is alternately moved up and down by the eccentric rod thereby resulting in a vertically reciprocated movement of one ornament, and the other end of the connection rod will be driven by the coupler thereby resulting in a reciprocated rotation of another ornament.
