Abstract
A vibration damping device for a motor vehicle, features a first movable element (13, 14) and a second movable element (15, 16) both rotatable around an axis X, at least one group of elastic members (25, 26) mounted between the first movable element and the second movable element and acting against rotation of the first movable element and second element with respect to one another, and a phasing member (32, 33) rotationally movable around the axis X. The first movable element (13, 14) and the second movable element (15, 16) are coaxial and capable of transmitting a torque. The phasing member (32, 33) includes a first portion (32) and a second portion (33), for arranging the elastic members of the at least one group in series so that the elastic members of each group deform in phase with one another.
