<p>A turning apparatus which turns a stirring head (24) of a stirrer wherein the stirring head is mounted to the end of an elevating shaft (21) provided to a cylindrical frame (20), and includes a guide rod (25) extending toward the lower portion along the frame. The guide rod is supported by an arm (26). The arm is rotatably mounted around the frame, and is rotated by a handle (31) through a worm gear device. A driving shaft of the worm gear (34,35) device can be prevented from rotating with use of a stopper. Upon rotation of the handle, the stirring head is turned around the frame through the arm and the guide rod, and is prevented from rotating at its stopped position. <IMAGE></p> |
