Tubular vibration-damping device

A structure in which a tubular vibration-damping device is mounted on a vehicle, the tubular vibration-damping device comprising:

• an inner shaft member;
• an outer tube member including an outer flange part at an axial end of the outer tube member;
• a main rubber elastic body connecting the inner shaft member and the outer tube member;
• and an axial stopper rubber protruding toward an axially outer side from the outer flange part and arranged in contact with a stopper contact surface such that the axial stopper rubber limits in cushioned fashion an amount of elastic deformation of the main rubber elastic body in an axial direction, the axial stopper rubber extending in a circumferential direction of the outer flange part, wherein
• a main load input direction with respect to the tubular vibration-damping device coincides with a center axis direction,
• the axial stopper rubber includes a plurality of lowered parts where a protrusion height of the axial stopper rubber is made small and are not in contact with the stopper contact surface in a mounted state, the plurality of lowered parts being spaced apart from each other in the circumferential direction while being arranged off portions of the axial stopper rubber that are opposed to each other in a maximum input direction of an axis-perpendicular vibration, and
• one pair of the plurality of lowered parts are opposed to each other in a direction perpendicular to the maximum input direction of the axis-perpendicular vibration.

• the plurality of lowered parts are all arranged off portions of the axial stopper rubber that are opposed to each other in the maximum input direction of the axis-perpendicular vibration identified by the directional indicator, and
• one pair of the plurality of lowered parts are opposed to each other in a direction perpendicular to the maximum input direction of the axis-perpendicular vibration identified by the directional indicator.
