Abstract
Provided is a stirring apparatus that can drive a stirring body with a simple structure and without applying excessive force. The stirring apparatus is provided with: the stirring body, which is a two-circle roller having an axis of rotation and two stirring fins; first and second drive shafts with axial centers not matching the axis rotation; a first shaft coupling, which connects the first drive shaft on a first stirring fin side of the axis rotation; a second shaft coupling, which connects the second drive shaft on a second stirring fin side of the axis of rotation; and a driving unit that exclusively carries out rotary drive of only either of the first and second drive shafts. The driving unit is provided with a regulating member that makes a teeth angular range of a first gear face a power-driven gear without play at a rotary position where the boundary between the teeth angular range and a missing teeth angular range of the first gear faces the power-driven gear and makes a teeth angular range of a second gear face the power-driven gear without backlash at a rotary position where the boundary between the teeth angular range and a missing teeth angular range of the second gear faces the power-driven gear.
