PROBLEM TO BE SOLVED: To provide a table type shaking device performing a shaking motion for fitting with the size of a container or a specimen housed in the container utilized for shaking culture, reaction, mixing, etc., capable of changing an eccentric radius of an assistant eccentric shaft for selecting the rotation radius of a shaking stand, automatically recognizing the size of the changed assistant eccentric shaft (so-called rotating radius) so as to realize the control of number of rotations for fitting to the shaft change, and also suppressing/preventing the temperature elevation over a standard temperature of the shaking device. SOLUTION: This shaking device equipped with a main body, the shaking stand installed at the upper part of the main body and loading/fixing an object, a rotating mechanism having a main eccentric shaft rotated/driven by a driving source and an assistant eccentric shaft rotated/driven as synchronized with the rotation of the main eccentric shaft and installed at the main body and rotating the shaking stand, and a controlling device for controlling the operation of the driving source is provided by making the assistant eccentric shaft as capable of selecting in a plurality of eccentric radii.
