STOPPER AND VIBRATION CONTROL UNIT

To provide a stopper capable of improving durability of a bracket.SOLUTION: A plate-shaped stopper is attached to a vibration control unit, wherein the vibration control unit comprises a first bracket fixed to one of a power unit side and a vehicle body side, a second bracket fixed to the other of the power unit side and the vehicle body side, an axial inside member to which the first bracket is fixed at an axial end part, and a vibration control substrate composed of a rubber-like elastic body that connects the outer peripheral surface of the inside member and the inner peripheral surface side of the cylindrical part of the second bracket; comprises a buffer part in which the first bracket and the cylindrical part are arranged between portions opposite in the axial direction of the cylindrical part; and is composed of a rubber-like elastic material. The buffer part comprises a thick part, a plurality of protrusions protruding from at least one surface in the thickness direction of the thick part, and a thin part thinner than the thick part.SELECTED DRAWING: Figure 2 【課題】ブラケットの耐久性を向上できるストッパを提供すること。【解決手段】パワーユニット側または車体側の一方に固定される第１ブラケットと、パワーユニット側または車体側の他方に固定される第２ブラケットと、第１ブラケットが軸方向端部に固定される軸状の内側部材と、内側部材の外周面と第２ブラケットの筒部の内周面側とを連結するゴム状弾性体から構成される防振基体と、を備える防振ユニットに取り付けられると共に、第１ブラケットと筒部とが筒部の軸方向に対向する部分の間に配置される緩衝部を備えてゴム状弾性体から構成される板状のストッパであって、緩衝部は、厚肉部と、厚肉部の板厚方向の少なくとも１面から突出する複数の突出部と、厚肉部よりも薄い薄肉部と、を備える。【選択図】図２
