This creation is a kind of rotary massaging device, comprising massage ontology, motor, eccentric shaking mould group, control mould group and operation mould group, to generate mild vibration, for massage. In particular, eccentric shaking mould group includes silicon steel sheet mould group, at least two fixing pieces, mandrel rod and anti-skidding fixing piece. This creation generates vibration using the eccentric shaking mould group of tool eccentric nature, especially, eccentric shaking mould group is to be combined into single silicon steel sheet mould group by stacking using multiple silicon steel sheets, therefore the mode not only make, assembled is simple, but also generated vibrating mode and intensity can more be reached by the stacking quantity of adjustment silicon steel sheet. Therefore, this creation can be very elastic and easily meet needed for practical application under conditions of not changing other elements.本創作係一種旋轉按摩裝置，包含按摩本體、馬達、偏心震動模組、控制模組以及操作模組，用以產生溫和的震動，可供按摩。尤其，偏心震動模組包含矽鋼片模組、至少二固定件、軸棒以及防滑固定件。本創作利用具偏心特性的偏心震動模組產生震動，尤其，偏心震動模組是利用多個矽鋼片藉堆疊而結合成單一的矽鋼片模組，因此不僅製作、組裝的方式簡單，而且所產生的震動模式及強度更可藉調整矽鋼片的堆疊數量而達成。因此，本創作能在不改變其他元件的條件下，很彈性且輕易的滿足實際應用所需。
