Abstract

A tubular vibration-damping device including: an inner axial member; an outer tubular member; and a main rubber elastic body connecting an outer peripheral surface of the inner axial member and an inner peripheral surface of the outer tubular member, wherein the outer peripheral surface of the inner axial member has an irregular shape including both lateral side faces with which a width of the inner axial member gets narrower in a lower side than in an upper side for an axis-perpendicular direction, and an inclination angle of a direction of each of the lateral side faces with which the width of the inner axial member gets narrower is larger in the lower side than in the upper side, and the lateral side faces respectively have groove-shaped concave portions formed extending continuously from the upper side to the lower side.
