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. |

1. A vibration damping device comprising:
a tubular first mounting member that is coupled to any one of a vibration generating portion and a vibration receiving portion; a second mounting member that is coupled to the other of the vibration generating portion and the vibration receiving portion and is inserted through the first mounting member; and an elastic body that is coupled to both of the mounting members, wherein a plurality of pressure-receiving liquid chambers, in which a liquid is enclosed and of which portions of wall surfaces are constituted of the elastic body, are disposed within the first mounting member, wherein the pressure-receiving liquid chambers have a pair of first pressure-receiving liquid chambers that communicate with each other through a first limiting path and a second pressure-receiving liquid chamber that communicates with an auxiliary liquid chamber, in which the liquid is enclosed, through a second limiting path, wherein the pair of first pressure-receiving liquid chambers sandwich the second mounting member therebetween, wherein the second pressure-receiving liquid chamber is arranged side by side with the second mounting member in an orthogonal direction orthogonal to both an axial direction of the first mounting member and a sandwiching direction in which the pair of first pressure-receiving liquid chambers sandwich the second mounting member, wherein the second mounting member extends over the entire length of each of the pair of first pressure-receiving liquid chambers and the second pressure-receiving liquid chamber in the axial direction, and wherein the first limiting path does not contact the auxiliary liquid chamber. |
