Abstract
A torsion damper for a locking clutch able to act between the driving element and the driven element of a hydrokinetic coupling device, has two coaxial parts able to move with respect to each other and counter to circumferentially acting springs, namely an input part provided with a guide washer and an output part provided with a web. The guide washer has a holding portion in the shape of a half-shell and bearing portions bordering on circumferentially extending apertures receiving the springs, to respectively hold the springs and enable them to bear. The web also has bearing portions to enable the springs to bear. The guide washer consists of two parts, a first part and a second part, assembled by crimping.
