PROBLEM TO BE SOLVED: To suppress the wobbling of a weight 3 in a dynamic damper D in which the weight 3 is elastically supported by a pair of vibration control bushes 2 by facilitating securing rigidity around a bush axis x while a spring characteristic in a vertical direction which is the vibration input direction is made flexible. SOLUTION: The vibration control bushes 2 is composed of an inner cylindrical member 5, an outer cylindrical member 6 and a rubber elastic body 7 for connecting them and provided with two pairs of legs 70 and 71 as its main springs extending between the inner and outer cylindrical members 5, 6 in a line-symmetric manner with respect to a vertical line V when viewed in a bush axis x direction. In a 1G state that the leg is viewed in the bush axis x direction, the upper side lag 70 extends substantially horizontally while a lower side log 71 extends inclining slightly downward from a horizontal direction.
