<p>PURPOSE:To provide a holding device for a rotary plate with which the rotary plate can be held without having a backlash, and with which the productivity can be improved. CONSTITUTION:A friction installation part 10b of a plate spring 10 is flexed to press a friction plate 20 toward a rotary plate 1, instead of flexing the friction plate 20 in the rotation direction of the rotary plate 1, so the friction plate 20 is pressed to both side surfaces 1b, 1c of the rotary plate 1 while motion of the friction plate 20 in the rotation direction of the rotary plate 1 is prevented. The rotary plate can thus be held securely without having a backlash. Precision work need not be applied to parts for composing a drive means for the plate spring 10, thereby the workability is improved, and the productivity is increased.</p> |
