A liquid-filled bushing, comprising: an inner tube which is connected to any one of a vibration generation portion and a vibration receiving portion; and an outer member which is disposed outside the inner tube in a radial direction and is connected to the other thereof, wherein the outer member defines a pair of liquid chambers between the inner tube and the outer member, and includes an orifice portion in which an orifice passage through which the pair of liquid chambers communicates with each other is formed, wherein the bushing further comprises an elastic body which elastically connects together the orifice portion and the inner tube, wherein the pair of liquid chambers are individually disposed on both sides between which a center axis of the inner tube is interposed in the radial direction between the inner tube and the orifice portion, wherein a first protrusion portion which protrudes outward in the radial direction and is fitted into the elastic body is formed in the inner tube, and a second protrusion portion which protrudes inward in the radial direction and is fitted into the elastic body is formed in the orifice portion, wherein the first protrusion portion and the second protrusion portion are disposed in both portions between the pair of liquid chambers adjacent in a circumferential direction such that positions of the first protrusion portion and the second protrusion portion in the circumferential direction coincide with each other and positions of the first protrusion portion and the second protrusion portion in the direction of the center axis are different from each other, and wherein the first protrusion portion and the second protrusion portion face each other in the direction of the center axis in a state where the elastic body is interposed therebetween, characterized in that each second protrusion portion is formed to extend in the circumferential direction of the orifice portion except for a portion of the orifice portion which defines the pair of liquid chambers. an inner tube which is connected to any one of a vibration generation portion and a vibration receiving portion; and an outer member which is disposed outside the inner tube in a radial direction and is connected to the other thereof, wherein the outer member defines a pair of liquid chambers between the inner tube and the outer member, and includes an orifice portion in which an orifice passage through which the pair of liquid chambers communicates with each other is formed, wherein the bushing further comprises an elastic body which elastically connects together the orifice portion and the inner tube, wherein the pair of liquid chambers are individually disposed on both sides between which a center axis of the inner tube is interposed in the radial direction between the inner tube and the orifice portion, wherein a first protrusion portion which protrudes outward in the radial direction and is fitted into the elastic body is formed in the inner tube, and a second protrusion portion which protrudes inward in the radial direction and is fitted into the elastic body is formed in the orifice portion, wherein the first protrusion portion and the second protrusion portion are disposed in both portions between the pair of liquid chambers adjacent in a circumferential direction such that positions of the first protrusion portion and the second protrusion portion in the circumferential direction coincide with each other and positions of the first protrusion portion and the second protrusion portion in the direction of the center axis are different from each other, and wherein the first protrusion portion and the second protrusion portion face each other in the direction of the center axis in a state where the elastic body is interposed therebetween, characterized in that each second protrusion portion is formed to extend in the circumferential direction of the orifice portion except for a portion of the orifice portion which defines the pair of liquid chambers.
