PROBLEM TO BE SOLVED: To sufficiently secure lubricating oil to be fed from a feeding side oil passage provided in a trunnion to each bearing provided around a power roller. SOLUTION: A supporting hole 23a for supporting a supporting shaft part 21 of a displacement shaft 7 is formed into a bottomed circular hole formed by blocking the outer surface side of a trunnion 6 by a bottom plate part 47. Lubricating oil discharged from a feeding side oil passage 39 to the supporting hole 23a is fed to bearings 25 to 27 without flowing out to the outer surface side of the trunnion 6. |
