The power of a driving unit is used for both the rotational motion of a rotary body and the translational motion of a holding part. The rotary body has a lower rotary board 312, a lower flange 313, a table 314, and an upper mounting board 315. This rotary body is driven by a motor 310. A gear 400 is provided on the outer circumferential surface of the upper mounting board 315. Gripping mechanisms 10 are arranged along a raceway 101, and neighboring gripping mechanisms 10 are connected to each other via a connection link 11. An upper roller 62 is provided in the gripping mechanisms 10. The upper roller 62 is engaged with the gear 400.本發明的壓縮成形裝置是將驅動部的動力共用於旋轉體的旋轉運動與保持部的移動運動。旋轉體,具有:下部轉盤(312)、下部突緣(313)、工作台(314)及上部安裝盤(315)。其旋轉體是藉著馬達(310)旋轉驅動。在上部安裝盤(315)的外圍面設有齒輪(400)。把持機構(10)是沿著軌道(101)排列,藉連結桿(11)連結把持機構(10)的相鄰彼此。在把持機構(10)設有上部滾子(62)。上部滾子(62)咬合於齒輪(400)。
