PROBLEM TO BE SOLVED: To provide an electronic device in which inadvertent rotation of a dial is avoided by obtaining sufficient and stable click torque even if the dial is miniaturized. SOLUTION: The electronic device comprises the dial 7 having a click part 7d of rugged shape at an inner peripheral part; a bearing part 1c supporting the dial 7 rotatably; and a spring member 8 of approximately C-shape mounted around the bearing part 1c and having a projecting part 8a projected radially outward at a part in a circumferential direction and elastically engaged with the click part 7d. Thin-walled parts 1e are provided in a predetermined circumferential range of portions, facing the projecting part 8a side, of the bearing part 1c. COPYRIGHT: (C)2009,JPO&INPIT
