Patent ID: 6921350

Claim:
A toroidal continuously variable transmission comprising: an input disk; an output disk facing the input disk; a power roller gripped between the input disk and output disk; a pedestal which supports the power roller free to rotate about a power roller rotation axis; a trunnion which gyrates about a trunnion gyration axis and comprises a first plane portion perpendicular to the power roller rotation axis, two second plane portions perpendicular to the first plane portion and facing each other across the power roller rotation axis, and two inclined portions between the first plane portion and the second plane portions, respectively; a roller bearing unit, comprising a cage housing a roller, that supports the pedestal on the trunnion so that the pedestal is free to slide in a direction that is perpendicular to both the trunnion gyration axis and power roller rotation axis; and limiting members, which limit the slide amount of the cage of the power roller bearing relative to the trunnion, are provided on the inclined portions.
