PROBLEM TO BE SOLVED: To provide an eccentric oscillation type speed reduction device capable of shortening an axial length.SOLUTION: An eccentric oscillation type speed reduction device 10 includes a crank shaft 16 and a crank shaft gear 18 connected to an end part 16A of the crank shaft. The eccentric oscillation type speed reduction device has a slip-off prevention member 70 contacting with an axial end surface 18Y of the crank shaft gear and preventing slip-off from the crank shaft of the crank shaft gear. In the crank shaft, a hollow part 80 is formed in an axial direction from an axial end surface 16B of the crank shaft, and a part of the slip-off prevention member is inserted into the hollow part and is fixed to the crank shaft in the hollow part.SELECTED DRAWING: Figure 2 |
