Abstract: The invention concerns a torque damper arranged between two rotating elements, an input element (51) and an output element (61),comprising resilient members (60) with circumferential action, two guide washers (52, 53) associated with (51) one of the elements and axially arranged on either side of a disc (54) associated with the other (61) element, the resilient members (60) operating between the two guide washers (52, 53) and the disc (54) by being placed in windows (64, 65, 66) located one opposite the others arranged in the guide washers (52,53) and in the disc (54), said windows (64, 65, 66) having two side edges (75, 76), on which are adapted to be urged to rest the ends of the resilient members (60) which form between them an angle (60) opening outward, the axis (70) of the resilient members (60) being a non-rectilinear curve with its concavity directed towards the common rotation axis of the input (51) and output (61) elements, such that the bearing surfaces of the ends of said resilient members (80) fo

Abstract: The invention concerns a torque damper arranged between an input element and a rotating output element, and comprising resilient members (60), with circumferential action, two guide washers associated with one of the elements and axially arranged on either side of a disc associated with the other element, the resilient members (60) operating between the two guide washers and the disc, by being placed in windows (64, 65), located opposite provided in the guide washers and in the disc.
