This invention discloses a circulative driving device of massagers, comprising a transmission shaft with one end connected to a driving motor； a driving bushing sleevedly fixed to one end of the transmission shaft opposite to the driving motor, wherein the peripheral surface of the driving bushing is made into a stick-slip surface； and a C-shaped shaft collar sleeved outside the driving bushing, wherein the C-shaped shaft collar has a plurality of rolling axles disposed as fixed axle rotation in parallel and at intervals to provide a circulative and inelastic belt body which is combined with a massager and carry the massager to displace, one section thereof is used to wind along the outside of the driving bushing and clamped in closely attaching manner between the C-shaped shaft collar and the driving bushing； as a result two side remaining sections of the inelastic belt body are respectively bent outwardly from an opening of the C-shaped shaft collar to form a continuous disposition. Accordingly, when a driving motor rotates the transmission shaft and drives the driving bushing to rotate in forward or reverse direction, in conjunction with rollings of the plurality of rolling axles inside the C-shaped shaft collar, the inelastic belt body can be driven on a limited position to move forward or backward along with a set rotational direction of the transmission shaft, so as to achieve the effect of circulatively driving the massagers at different upper and lower positions.本發明揭露一種按摩器循環驅動裝置，包括傳動軸，其一端連接驅動馬達；驅動軸套，係套固在傳動軸相對驅動馬達的一端；驅動軸套的外圍周面製成為滯滑面；以及C型軸環，套設在驅動軸套外，C型軸環具有複數個滾動軸，以平行、間隔方式設置為定軸旋轉，使提供結合與攜帶按摩器位移的循環狀、不具彈性之帶體，以其中一段貼沿驅動軸套外側折繞，並得以緊貼方式夾滯在C型軸環與驅動軸套間；而令不具彈性之帶體兩側餘段，分別從C型軸環的開口處朝外折出，形成延續設置；藉此，當驅動馬達轉動傳動軸暨驅動軸套正或反向轉動時，由C型軸環內側複數滾動軸的配合滾動，即可帶動不具彈性之帶體在被限定的位置上，隨著傳動軸設定的轉動方向移動前進或後退，達到不同上、下位置的按摩器循環驅動效果者。
