ABSTRACT:
A torsion damper comprises a main damper plate surrounding a hub, and a pre-damper mounted on one side of the main damper plate and having a housing which is coupled to the main damper plate for rotation with the latter, by coupling fingers each of which is engaged in a complementary aperture formed in the main damper plate. Guide rings of the pre-damper are retained axially between a first shoulder formed on a set of resiliently deformable hooked tongues, and a second shoulder, with both these shoulders being carried by the housing.
Each hooked tongue extends radially inside a corresponding coupling finger and is also arranged to penetrate into the aperture corresponding to the associated coupling finger.
