Abstract
Official abstract text for this publication.
Provided with first and second rotational members, a sun roller, a plurality of planetary balls sandwiched between the first and second rotational members, a support shaft of each of the planetary balls, a shaft, a carrier, an iris plate and a worm gear for tilting each of the planetary balls, and an input shaft and an output shaft individually fixed to the first and second rotational members, respectively, in which a movable amount of the sun roller relative to the carrier in an axis line direction is set to be smaller than the movable amount of the second rotational member relative to the carrier in the axis line direction when the input shaft is arranged so as to be relatively rotatable on an outer peripheral surface of the output shaft.
First claim
Opening claim text (preview).
The invention claimed is: 1. A continuously variable transmission, comprising: a transmission shaft as a fixed shaft being a center of rotation; a relatively rotatable first rotational element and a relatively rotatable second rotational element having a common first central axis of rotation arranged so as to be opposed to each other on the transmission shaft; a plurality of rolling members each having a second central axis of rotation parallel to the first central axis of rot…
