VIBRATION ISOLATOR

[Problem]To provide a vibration isolator configured such that a press-fit portion is less likely to come off from a press-fitted portion.[Solution]Any one of a bracket (2) and a first attachment tool (3) includes a press-fit portion (12). The press-fit portion (12) has a rigidity higher than a rigidity of an elastic body. The press-fit portion (12) projects out from a rear end (12b) toward a distal end (12a) in a press fitting direction (A). Another one of the bracket (2) and the first attachment tool (3) includes a tubular press-fitted portion (20, 32). The press-fit portion (12) is press-fitted to the press-fitted portion (20, 32) in the press fitting direction (A). The press-fitted portion (20, 32) includes: a tubular rigid portion having an inner surface with recesses (27) depressed with respect to both front and rear sides in the press fitting direction (A), the rigid portion (22) having at least one end with an open end portion (24a, 24b), the rigid portion (22) having a rigidity higher than a rigidity of the elastic body; and an elastic film portion (23a, 33) made of an elastic body bonded to an inner surface of the rigid portion (22). The press-fit portion (12) includes: a first protrusion portion (16, 31) projecting in a direction perpendicular to the press fitting direction (A), the first protrusion portion (16, 31) biting into the elastic film portion (23a, 33); and a second protrusion portion (17) that partially overlaps with the rigid portion (22) as viewed in the press fitting direction (A) with the second protrusion portion (17) located inside the recess (27).
