Abstract
A friction transmission device includes: an input trajectory ring; a planetary rolling body that is disposed about a rotation axis line of the input trajectory ring and that comes into contact with the input trajectory ring; an output trajectory ring that comes into contact with the planetary rolling body and that is connected to an output member, and a first support trajectory ring and a second support trajectory ring that come into contact with the planetary rolling body; in which at least one of the input trajectory ring, the output trajectory ring, the first support trajectory ring, or the second support trajectory ring is a convex-concave contact trajectory ring that comes into convex-concave contact with the planetary rolling body.

A friction transmission device comprising:
- an input trajectory ring;
- a planetary rolling body that is disposed about a rotation axis line of the input trajectory ring and that comes into contact with the input trajectory ring;
- an output trajectory ring that comes into contact with the planetary rolling body and that is connected to an output member;
- and
- a first support trajectory ring and a second support trajectory ring that come into contact with the planetary rolling body,
- wherein at least one of the input trajectory ring, the output trajectory ring, the first support trajectory ring, or the second support trajectory ring is a convex-concave contact trajectory ring that comes into convex-concave contact with the planetary rolling body.
