Abstract
Lateral wear of a contact position of a cam face of a precess cam which displaces in response to the gyrational state of a power roller and a cam follower which is provided on a feedback link is reduced. The cam follower (55) which contacts with the cam face (54) of the precess cam (52) is mounted on the feedback link (53) and the cam follower (55) comprises a three-dimensional curve such a rotating barrel-shaped body. Even if the cam face (54) of the precess cam (52) inclines, the cam follower (55) is normally maintained in a stable contact state. In this way, wear is reduced and durability is increased.
