PROBLEM TO BE SOLVED: To provide an antivibration device capable of improving control stability and durability. SOLUTION: In a body rubber 50, a projection 58, which projects from a circular arc side body rubber section 56 to a projection body rubber section 53 side, and when first inside hardware 20 is relatively displaced in a direction approaching outside hardware 40 between the first inside hardware 20 and the outside hardware 40, regulates a relative displacement of the first inside hardware 20 with respect to the outside hardware 40 by contacting with a projection 42 of the outside hardware 40. Furthermore, a perpendicular dimension of the second primary section 63, a primary section at a tube section 22 side of the first inside hardware 20 more inside than the projection 58, is set larger than a perpendicular dimension of a first primary section 62 i.e., a primary section in the projection. Therefore, this can prevent cracks from a circular arc inner periphery section 63a of the second primary section 63 to a connection 52 of the body rubber 50 and a durability of a strut mount 1 can be improved.
