PURPOSE:To provide a bearing device enabling generation of stable resistance torque while reducing the number of parts. CONSTITUTION:A plate spring 14 is inserted in the holding groove 22 of a bearing holder 12 from tip open parts 14A. A shaft 32 is then inserted through, and a small diameter part 34 is journalled into shaft holes 28, 30. The circular arc parts 14B of the plate spring 14 thereby come in surface contact with the outer peripheral surface of the small diameter part 34 of the shaft 32 so as to hold the shaft 32 in the state of being wrapped in from both sides. The circular arc parts 14B are pressed by ribs 52. Since the plate spring 14 is thus pressed always by the wall surface of the holding groove 22, frictional force to the shaft 32 is constant, so that resistance torque is stabilized. |
