PURPOSE:To provide the title mechanism reduced in the number of parts and facilitated in the maintenance, designed to make changeover between rotary shaking mode and linearly reciprocating shaking mode, through the combination of the fixation and release of a bearing by a fixing body with the fixation and release of connecting bodies. CONSTITUTION:A shaking body 13 is provided with guide rails 17a, 17b rectangular to guide rails 10a, 10b, and two pairs of guide rails are mutually connected with connecting bodies 26a-26d so as to be slidable, respectively. An eccentric shaft 12 is connected to a bearing 19 moving along the long direction of the guide rails 17a, 17b and this bearing is fixed to the shaking body 13 through fixing bodies 24a, 24b. A changeover is made between rotary shaking mode and linearly reciprocating shaking mode by moving said fixing bodies 24a, 24b through rotating a handle 23a. Thus, the objective simple shaking mechanism consisting of only a single driving system made up of a driving shaft 6, rotator 11 and the eccentric shaft 12 can be obtained without the need of a rest for the changeover of shaking direction.
