This continuously variable transmission device is provided with: an input shaft (20); an output shaft (30); an input roller (50); an output ring (80); a transmission ring (90); a plurality of planetary rollers (60) having a first conical section (61), which contacts the outside of the input roller and contacts the inside of the output ring, and a second conical section (62), which contacts the inside of the transmission ring; a mobile holder (70) that holds the plurality of planetary rollers in a manner able to rotate around the respective rotational axes and in a manner so as to be able to revolve around a central axis; and loading cam mechanisms (CM1, CM2) that generate a thrust loading. The surfaces (52, 82, 91) of the input roller (50), output ring (80), and transmission ring (90) that contact the planetary rollers are formed in a convex curved surface having a predetermined curvature, and the planetary rollers (60) are held in the mobile holder in a manner so that the angle of obliquity of the rotational axes (S) with respect to the central axis is variable. As a result, it is possible to automatically balance the moment acting on the planetary rollers to a position that is constantly sero. |
