A filtering mechanism for torque fluctuations is interposed between a crankshaft of an internal combustion engine and a transmission. This mechanism comprises a rotating member to be damped, an oscillating inertial flywheel rotating around the axis of revolution, and pivot-mounted modules allowing angular deflection of the oscillating inertial flywheel with respect to the member to be damped. The modules each have at least one oscillating arm pivoting radially with respect to the member to be damped and a kinematic connecting member between the oscillating arm and the oscillating inertial flywheel. When the mechanism rotates centrifugal forces on the oscillating arm produce a counteracting torque that tends to return the oscillating inertial flywheel and the member to be damped toward the equilibrium position. The counteracting torque increases with the rotation speed of the filtering mechanism and with the amplitude of the angular deflection.
