A vibration-damping device comprising: a tubular first attachment member coupled to any one of a vibration generating part and a vibration receiving part, and a second attachment member coupled to the other thereof; an elastic body that couples the first attachment member and the second attachment member together; and a partitioning member that partitions a liquid chamber within the first attachment member having a liquid enclosed therein into a first liquid chamber and a second liquid chamber, wherein at least one of the first liquid chamber and the second liquid chamber has the elastic body on a portion of a wall surface thereof, wherein a limiting passage (31, 32) that allows the first liquid chamber and the second liquid chamber to communicate with each other is formed in the partitioning member, wherein the limiting passage (31, 32) includes a first limiting passage that causes resonance with respect to the input of an idle vibration, and a second limiting passage that causes resonance with respect to the input of a shake vibration, wherein an inner peripheral surface of the first limiting passage is provided with a flow changing protrusion (33, 34, 36, 41, 42, 43, 44) that protrudes toward an inner side in a radial direction of the first limiting passage and that changes the flow of a liquid that flows through the first limiting passage in an axial direction of the first limiting passage, wherein, in a vertical cross-sectional view passing through an axis of the first limiting passage and through the flow changing protrusion (33, 34, 36, 41, 42, 43, 44), the first limiting passage and the flow changing protrusion (33, 34, 36, 41, 42, 43, 44) have symmetrical shapes with respect to the axis, and wherein a protruding end of the flow changing protrusion (33, 34, 36, 41, 42, 43, 44) forms an inner peripheral edge of a passage hole (33c, 34c, 41c, 42c, 43c, 44c) that is open on both sides in the axial direction, characterised in that the flow changing protrusion (33, 34, 36, 41, 42, 43, 44) is formed integrally with the partitioning member as a rigid body having such rigidity that the flow changing protrusion (33, 34, 36, 41, 42, 43, 44) is not deformed when the flow of the liquid is received by the flow changing protrusion (33, 34, 36, 41, 42, 43, 44). a tubular first attachment member coupled to any one of a vibration generating part and a vibration receiving part, and a second attachment member coupled to the other thereof; an elastic body that couples the first attachment member and the second attachment member together; and a partitioning member that partitions a liquid chamber within the first attachment member having a liquid enclosed therein into a first liquid chamber and a second liquid chamber, wherein at least one of the first liquid chamber and the second liquid chamber has the elastic body on a portion of a wall surface thereof, wherein a limiting passage (31, 32) that allows the first liquid chamber and the second liquid chamber to communicate with each other is formed in the partitioning member, wherein the limiting passage (31, 32) includes a first limiting passage that causes resonance with respect to the input of an idle vibration, and a second limiting passage that causes resonance with respect to the input of a shake vibration, wherein an inner peripheral surface of the first limiting passage is provided with a flow changing protrusion (33, 34, 36, 41, 42, 43, 44) that protrudes toward an inner side in a radial direction of the first limiting passage and that changes the flow of a liquid that flows through the first limiting passage in an axial direction of the first limiting passage, wherein, in a vertical cross-sectional view passing through an axis of the first limiting passage and through the flow changing protrusion (33, 34, 36, 41, 42, 43, 44), the first limiting passage and the flow changing protrusion (33, 34, 36, 41, 42, 43, 44) have symmetrical shapes with respect to the axis, and wherein a protruding end of the flow changing protrusion (33, 34, 36, 41, 42, 43, 44) forms an inner peripheral edge of a passage hole (33c, 34c, 41c, 42c, 43c, 44c) that is open on both sides in the axial direction, characterised in that the flow changing protrusion (33, 34, 36, 41, 42, 43, 44) is formed integrally with the partitioning member as a rigid body having such rigidity that the flow changing protrusion (33, 34, 36, 41, 42, 43, 44) is not deformed when the flow of the liquid is received by the flow changing protrusion (33, 34, 36, 41, 42, 43, 44).
