Title: VIBRATION DAMPING DEVICE
Abstract:
A vibration damping device (10) is provided with: a cylindrical outer mounting member (11); an inner mounting member (12); a pair of body rubber sections (13) for connecting the outer mounting member (11) and the inner mounting member (12) and arranged at a distance from each other in an axial direction extending along the center axis (O) of the outer mounting member (11); and a partition section (15) for connecting the outer mounting member (11) and the inner mounting member (12) and axially dividing a liquid chamber (25) located between the pair of body rubber sections (13) into a first liquid chamber (26) and a second liquid chamber (27). The partition section (15) is provided with: an annular rigid body section (30) having formed therein a restriction passage (33) for providing communication between the first liquid chamber (26) and the second liquid chamber (27); and an annular elastic section (29) radially interconnected with the rigid body section (30). The elastic section (29) is in contact, in a non-adhered state, with the rigid body section (30) while being radially compressed and deformed.
