PROBLEM TO BE SOLVED: To provide a small driving device that cantilever-supports and rotates a rotated member.SOLUTION: A driving device comprises a first speed reducer 230a and a second speed reducer 230b. The first speed reducer 230a comprises a crank shaft 212a, an eccentric rotation gear 208a, and a rotation gear 206a. The second speed reducer 230b comprises a crank shaft 212b, an eccentric rotation gear 208b, and a rotation gear 206b. The eccentric rotation gears 208a, 208b eccentrically rotate as the crank shafts 212a, 212b rotate. The rotation gears 206a, 206b are meshed with the eccentric rotation gears 208a, 208b, and arranged coaxially with a rotation shaft 260 of an output part 262a. The eccentric rotation gear 208a of the first speed reducer 230a and the eccentric rotation gear 208b of the second speed reducer 230b are decentered to the rotation shaft 260 of the output shaft 262a. |
