PROBLEM TO BE SOLVED: To provide a driving device capable of extending a life of a crank shaft bearing of a swing gear device.SOLUTION: This invention relates to a driving device D1 including: a swing gear device 10 comprising a swing gear 12, a crank shaft 14 for swinging the swing gear and a carrier 31 supporting the crank shaft through a crank shaft bearing 35; and a mating member 42 connected to the carrier 31. The carrier has a first through-pass hole 51 where the crank shaft bearing is provided and a second though-pass hole 52 provided at a position displaced in a radial direction from the first through-pass hole. The mating member is fixed to an end surface 31E at a counter-swing gear of the carrier and a recess part 42A over the first through-pass hole and the second through-pass hole is formed on a fixing surface 42E for the carrier of the mating member.SELECTED DRAWING: Figure 1 |
