A torsion damper for a vehicle powertrain includes a first element having a support element and a second element movable in rotation with respect to the first element about an axis of rotation X. Springs are mounted between the first element and the second element so as to compress to allow relative rotation about the X axis between the first element and the second element. A friction device including a friction washer provided with at least one fixing portion rigidly fixed in rotation on a support element of the first element, the friction washer having a friction portion having a friction track backed against a dorsal face of the friction portion. An elastic washer arranged axially between the first element and the dorsal face of the friction portion, each fixing portion for fixing to the first element being connected to the friction portion by a flexible element allowing axial displacement of the dorsal face of the friction portion relative to the support element of the first element.

A torsion damping device for a vehicle transmission including a first rotary element and a second rotary element which are able to move in rotation relative to one another about an axis against the action of a spring acting circumferentially between these, a seat being positioned on one end of the spring, this seat comprising a first axial guidance arrangement providing axial guidance between the first rotary element and the seat, and a second axial guidance arrangement providing axial guidance between the second rotary element and the seat.
