Claim:
1. A continuously variable transmission device for transmitting a rotational movement, comprising: a driving bell rotating around a first axis; a driven bell rotating around a second axis aligned with the first axis; a planet gear provided with a first belt in contact with an inner surface of the driving bell and a second belt in contact with an inner surface of the driven bell, contact zones between said belts and the inner surfaces of the bells being defined in a same first radial plane relative to the first axis, while the planet gear rotates around a third axis included in the first radial plane and an angular orientation of which relative to the first axis defines the transmission ratio of the device and while the planet gear pivots around a fourth axis perpendicular to the first radial plane and not intersecting the first axis; wherein the planet gear pivots around a fifth axis parallel to the first radial plane and perpendicular to the third axis.
