The present invention provides a cylindrical anti-vibration device for a motor mount having a novel structure and capable of improving anti-vibration performance against high-frequency vibration which is a problem in the motor mount. An inner shaft member (12) and an outer cylinder member (14) are connected through a main body rubber elastic body (16), and the main body rubber elastic body (16) is provided with a plurality of rubber legs (20) which extend from the inner shaft member (12) to the outer cylinder member (14) and connect the inner shaft member (12) and the outer cylinder member (14) with each other. The rubber leg (20) is provided with a plurality of vibration-damping protrusions (30, 32) which protrude on the surface and are located at an intermediate portion separated from either the inner shaft member (12) or the outer cylinder member (14) in the connection direction, and the plurality of vibration-damping protrusions (30, 32) are arranged in parallel and spaced apart from each other in the connection direction of the rubber leg (20).
本发明提供能够实现针对在马达安装件中成为问题的高频振动的防振性能的提高的、新型结构的马达安装件用筒型防振装置。内轴构件12与外筒构件14通过主体橡胶弹性体16连结而成的马达安装件用筒型防振装置10,其中,主体橡胶弹性体16具备从内轴构件12朝向外筒构件14延伸而将这些内轴构件12与外筒构件14相互连结的多个橡胶脚20,在橡胶脚20设置有在连结方向上位于从内轴构件12与外筒构件14的任一方分离的中间部分且在表面上突出的多个减振突部30、32,这些多个减振突部30、32在橡胶脚20的连结方向上相互分隔而并列地配置。
