The second element includes first and second axially spaced lateral washers mounted coupled in rotation. The first element includes an intermediate disc arranged axially between the lateral washers. Springs are mounted between the first and second element to allow relative rotation between the first and second element. A first friction device includes a first friction washer arranged between the first lateral washer and first element, and a first elastic washer arranged axially between the first element and the first friction washer. A second friction device includes a second friction washer arranged between the second lateral washer and the first element, and a second elastic washer arranged axially between the first element and the second friction washer.
