Abstract
A tubular vibration damping device has a structure in which an inner shaft member is connected with an outer tube member made of synthetic resin by a body rubber elastic body. The outer tube member has a structure in which a tubular part extends in an axial direction from an inner peripheral end of a flange of an annular plate shape. A press fit rubber is fixed to an outer peripheral surface of the tubular part, and an axial surface of the flange on a side from which the tubular part extends is exposed without being covered with the press fit rubber. A notch penetrating in a radial direction is provided at an axial end of the outer tube member that includes the flange. A connecting rubber that connects the body rubber elastic body and the press fit rubber is provided in the notch.
