To provide a cylindrical vibration control device for a motor mount having a novel structure which can secure durability and attain greater freedom in characteristics tuning while reducing deterioration of vibration control performance by surging of rubber legs.SOLUTION: In a cylindrical vibration control device 10 for a motor mount, an inner shaft member 12 and an outer cylinder member 14 are connected by two rubber legs 16, 16 extending between opposed surfaces of the inner shaft member 12 and the outer cylinder member 14. The two rubber legs 16, 16 are both disposed on the lower side of the inner shaft member 12, which is the compression side when a main load is input, and extend in a vertical direction at positions separated from each other in a lateral direction. The two rubber legs 16, 16 have connection rubber parts 26, 26 which are continuous in the vertical direction and directly connect the opposed surfaces of the inner shaft member 12 and the outer cylinder member 14. The two rubber legs 16, 16 are each provided with a rubber projection 28 projecting in an axial direction. The rubber projection 28 is disposed fitted in the inner side of the connection rubber part 26 in the lateral direction relative to left and right outer edges of the connection rubber part 26.SELECTED DRAWING: Figure 2

    【課題】ゴム脚のサージングによる防振性能の低下を抑えつつ、耐久性を確保し、更に特性チューニングの自由度を大きく得ることができる、新規な構造のモータマウント用の筒型防振装置を提供する。【解決手段】インナ軸部材12とアウタ筒部材14とがそれらの対向面間を延びる2つのゴム脚16,16によって連結されたモータマウント用の筒型防振装置10であって、2つのゴム脚16,16は、何れも主たる荷重入力時に圧縮側となるインナ軸部材12の下側に配置されて、左右方向で相互に離れた位置で上下方向に延びており、2つのゴム脚16,16が上下方向に連続してインナ軸部材12とアウタ筒部材14との各対向面間を直接に連結する連結ゴム部26,26を備えており、2つのゴム脚16,16には、軸方向に突出するゴム突起28がそれぞれ設けられており、ゴム突起28が連結ゴム部26の左右外端よりも左右内側へ収まる状態で配されている。【選択図】図2
