To provide a cylindrical anti-vibration device for a motor mount, which has a novel structure and can achieve improvement of the anti-vibration performance against high-frequency vibration that poses a problem in a motor mount.SOLUTION: A cylindrical anti-vibration device 10 for a motor mount has an inner shaft member 12 and an outer cylinder member 14, which are connected by a main rubber elastic body 16. The main rubber elastic body 16 comprises a plurality of rubber legs 20 that extend from the inner shaft member 12 toward the outer cylinder member 14, and that connect the inner shaft member 12 and the outer cylinder member 14 to each other. The rubber legs 20 are provided with a plurality of vibration control protrusions 30, 32 that are located in an intermediate portion spaced apart from both the inner shaft member 12 and the outer cylinder member 14 in the connection direction, and that protrude from a surface. The plurality of vibration control protrusions 30, 32 are disposed in parallel so as to be spaced apart from each other in the connection direction of the rubber legs 20.SELECTED DRAWING: Figure 1

    【課題】モータマウントにおいて問題となる高周波振動に対する防振性能の向上を実現することができる、新規な構造のモータマウント用筒型防振装置を提供すること。【解決手段】インナ軸部材12とアウタ筒部材14が本体ゴム弾性体16によって連結されたモータマウント用筒型防振装置10であって、本体ゴム弾性体16は、インナ軸部材12からアウタ筒部材14へ向けて延びてそれらインナ軸部材12とアウタ筒部材14を相互に連結する複数のゴム脚20を備えており、ゴム脚20には、連結方向においてインナ軸部材12とアウタ筒部材14の何れからも離れた中間部分に位置して表面上に突出する複数の制振突部30,32が設けられており、それら複数の制振突部30,32がゴム脚20の連結方向で相互に離隔して並列的に配置されている。【選択図】図1
