PROBLEM TO BE SOLVED: To provide a structure by which a bearing part can easily be moved when a rotary board is removed for cleaning or the like in a rotary powder compression molding machine. SOLUTION: A rotary board 3 is horizontally rotatably placed in a frame 1 via a vertical shaft 2. The rotary board is provided with plural mortars at prescribed pitches. Further, an upper pestle 5 and a lower pestle 6 are held to the upper and lower parts of each mortar slidably in the upper and lower directions. The upper pestle and the lower pestle whose tips are inserted into the mortars are passed through the space between an upper roll 7 and a lower roll 8, so that powders filled into the mortars are subjected to compression molding. The machine is provided with a bearing means rotatably supporting the upper roll, a bearing fitting means fixing the bearing means by pressing the same to the frame not to be moved, and further movably supporting the bearing means when the pressure is released, and a guiding and moving means moving the bearing means when the bearing fitting means releases the pressure.
