Abstract

A tubular vibration damping device includes an inner shaft member and an outer tube member connected by a main body rubber elastic body. The inner shaft member is provided with a large-diameter part having an outer diameter dimension that is configured to be large at an axial middle portion. The main body rubber elastic body is provided with a through hole penetrating in an axial direction and extending for a predetermined length in a circumferential direction. The through hole has circumferentially opposing inner surfaces at least one of which is provided with an inclined surface that expands such that a circumferentially opposing surface distance gradually increases toward an axial opening part of the through hole.
