<p>A speed reduction device includes front and rear stage speed reduction mechanisms. The speed reduction device includes a connecting shaft that connects the front stage speed reduction mechanism to the rear stage speed reduction mechanism; bearings that support the connecting shaft; an oil supply port that is formed on one side of front and rear stage sides of the bearings; and communication passages that make a receiving section, which is closer to the front stage speed reduction mechanism than the bearings in a casing of the speed reduction device, communicate with a receiving section, which is closer to the rear stage speed reduction mechanism than the bearings.</p> |
