PROBLEM TO BE SOLVED: To reduce manufacturing cost and provide excellent lubrication of an engaging part between a bearing, a sprocket, and a chain. SOLUTION: In an output device wherein a sprocket 7 is coupled to the output train of a continuously variable transmission, an oil discharge passage 25 through which oil to lubricate bearings 11a and 11b is discharged is provided. The inner peripheral part 27 of the tooth part ring part 26 of a sprocket 7 is radially externally positioned in the oil discharge passage 25. A guide part 28 to guide oil, discharged through the oil discharge passage 25, to the inner peripheral surface 27 of the tooth part ring part 26 of the sprocket 7 along a sprocket side face 24 or bearing support walls 10a and 10b or by flying through a space is formed between the sprocket side face 24 and the bearing support walls 10a and 10b. |
