In a vibration damping device (10), a plurality of pressure-receiving liquid chambers (25, 26) of which portions of wall surfaces are constituted of an elastic body (14) are disposed within the first mounting member (12). The pressure-receiving liquid chambers (25, 26) include a pair of first pressure-receiving liquid chambers (25) that communicate with each other through a first limiting path (27), and a second pressure-receiving liquid chamber (26) that communicates with an auxiliary liquid chamber (28) through a second limiting path. The pair of first pressure-receiving liquid chambers (25) sandwich a second mounting member (13) therebetween. The second pressure-receiving liquid chamber (26) is arranged side by side with the second mounting member (13) in an orthogonal direction (D1) orthogonal to both an axial direction of the first mounting member (12) and a sandwiching direction (D2) in which the pair of first pressure-receiving liquid chambers (25) sandwich the second mounting member (13). The second mounting member (13) extends over the entire length of each of the pair of first pressure-receiving liquid chambers (25) and the second pressure-receiving liquid chamber (26) in the axial direction. The first limiting path (27) does not contact the auxiliary liquid chamber (28). According to the vibration damping device (10), the performance of the elastic body (14) can be easily maintained for a prolonged period of time. |
