1. A tubular vibration-damping device comprising an inner shaft member and an outer tube member connected by a main rubber elastic body, the outer tube member being configured to be attached to an attachment tube in an inserted state where the outer tube member is slidable in an axial direction, wherein
the outer tube member is divided at least at a part in a circumferential direction and is deformable or displaceable in a radial direction,
a pair of tighteners are disposed on axially opposite sides of the main rubber elastic body,
the main rubber elastic body is fastened to an inner circumferential surface of the outer tube member,
an adjustment elastic body against which the pair of the tighteners are pressed is integrally formed with axially opposite side portions of the main rubber elastic body, and
sliding resistance in the axial direction between an outer circumferential surface of the outer tube member and an inner circumferential surface of the attachment tube is settable depending on a pressing force of the pair of the tighteners against the adjustment elastic body.
