PROBLEM TO BE SOLVED: To improve the durability of a caulking part 7 which is a part caulked to a flange 12 of a stopper bracket 4 in an anti-vibration device 10 comprising: an annular bracket 1 in which the flange 12 protruding to the outside circumferential side is formed at the upper end of a tubular body; a center bracket 2 which is provided at the upper side of the center line of the annular bracket 1 with an interval; a rubber member 3 which is arranged between the annular bracket 1 and the center bracket 2 and connects these brackets; and the stopper bracket 4 which functions as a stopper for limiting the relative displacement of the annular bracket 1 and the center bracket 2, and in which a window 9 for draining water is formed by cutting out a part of the circumferential direction of the stopper bracket 4. SOLUTION: An angle of circumference formed of a plane passing the center line and a point in the window at a position corresponding to a tubular part 5 and a plane passing the center line and a point on the edge of the window 9 is small at the tubular part 5 and a plate 8 and large at the caulking part 7 at either side of both right and left edges.
