In a vibration control equipment 1 constituted by inserting an outer tube 20 of pair of damping rubbers 2A, 2B into an opening 30 of a bracket member 3, clamping the pair of damping rubbers 2A, 2B by means of plate members 4A, 4B, tightening a fastening member 5 for coupling the plate members 4A, 4B, and then compressing the rubber elastic bodies 22 of the damping rubbers 2A, 2B in the axial direction, the outside diameter of the outer tube 20 before tightening the fastening member 5 is smaller than the inside diameter of the fixing hole 30, the rubber elastic bodies 22 are compression deformed by tightening the fastening member 5 and thus a bracket member 3 is clamped by means of upper and lower flange portions 23, at least one of the rubber elastic bodies 22 is provided with mold cavity portions 26A, 26B and at least one of the pair of outer tubes 20 is provided with a positioning portion 24 for determining the circumferential position of the pair of damping rubbers 2A, 2B relative to the bracket member 3. According to the present invention, assembling work is facilitated by arranging the mold cavity portions in accordance with the direction of vibration and the production cost can be reduced.
