Abstract

A driving mechanism of music snow drop ball, which provides waterproof effect for avoiding rusting of the mechanism. The driving mechanism includes a water ball and a base disposed under the water ball for containing a seat member, an upper and a lower silicone gaskets, a central shaft rod, a fastening plate and a propeller. Each of the gaskets is formed with an inner and an outer rings defining an annular groove, whereby when assembled with the shaft rod, in the case that the water infiltrates back, the water will accumulate in the annular groove to create a fastening pressure which makes the gasket to bind the shaft rod. Therefore, the water is prevented from infiltrating back into the driving mechanism so as to avoid rusting of the driving mechanism.
