Amendment June 17, 1981 The name of the invention is amended as follows. Title of the invention: Cylindrical anti-vibration bushing The scope of the claims for utility model registration and the brief description of the drawings are amended as follows.

[Scope of Claim for Utility Model Registration] (1) In a cylindrical anti-vibration bushing in which an elastic body having a deformation relief space on both sides in the direction of load action with respect to the axis is interposed between the inner cylinder and the outer cylinder. A cylindrical anti-vibration bushing, characterized in that the inner cylinder is configured to be expandable within a cross section perpendicular to the axis. (2) The cylindrical anti-vibration bushing according to claim 1, wherein the expandable structure of the inner cylinder is constructed by dividing the inner cylinder into multiple parts in the circumferential direction. (3) The expandable structure of the inner cylinder is such that the inner cylinder is not divided in the circumferential direction and the inner cylinder is made of a non-rigid body that can be expanded.
Cylindrical anti-vibration bushing as described in Section 1. (4) Registration of a utility model in which the expandable structure of the inner cylinder is constructed by providing a notch to serve as a hinge at one location in the circumferential direction of the inner cylinder and a cutout at a position opposite to the notch in the inner cylinder. A cylindrical anti-vibration bushing according to claim 1.
