PROBLEM TO BE SOLVED: To realize a structure capable of preventing fretting wear based on the elastic deformation of an input side disk 8a and sufficiently securing the amount of a lubricating oil fed to a radial needle bearing 31c rotatably pivoting a planetary gear 30. SOLUTION: The lubricating oil fed from the lubricating oil flow passage 50 of an input shaft into a lubricating oil flow passage 53 in a first carrier 21 is fed to the radial needle bearing 31c through a recessed part 58 formed in the axial end face of the first carrier 21 and a second lubricating oil flow passage 60 formed in a third planetary shaft 27. Also, a copper or copper-based alloy thrust plate 63 is held between the first carrier 21 and the input side disk 8a. COPYRIGHT: (C)2006,JPO&NCIPI
