A device for filtering vibration between two parts (2 and 3), includes: at least a first resilient plate (4) connected to the parts (2 and 3) at two respective fastener points at two respective points (2A and 3A), the first plate (4) being locally deformable under the action of vibration transmitted by one of the parts to the other part; and at least a first resonator (7) fitted with two laminated elastomer bearings (8, 9) receiving respective fastener elements (80, 90) fastening it to the first resilient member (4) in such a manner as to set the resonator (7) into oscillating pivoting motion in the event of the local deformation of the first resilient plate (4) such that the resonator (7) generates an anti-vibratory inertia torsor that opposes the vibration and filters transmission thereof from one part to the other.
