The invention relates to a device (10) for torsionally damping a drive shaft, which comprises: - a radial support washer (38A) rotationally driven by the drive shaft; - two pendular flyweights (54A, 54B) mounted axially one on each side of the support washer (38A) such that they can oscillate; - a pin (58, 74), a central portion (66, 82) of which is housed such that it can slide in an associated guide slot (68, 80) of the support washer (38A); characterized in that the support washer (38A) bears a front radial abutment face (88B, 100B) and a rear radial abutment face (88A, 100A), and in that the central portion (66, 82) of the pin (58, 74) has two opposite shoulder faces (90A, 90B, 104A, 104B) which are housed between the two abutment faces (88A, 88B, 100A, 100B). |
