Abstract
In a cylindrical mount in which an inner member and an outer cylindrical member are connected by a main rubber elastic body in a cylindrical shape, the inner member includes a cup member open toward the main rubber elastic body, an end of the main rubber elastic body in an axial direction is inserted and installed to the cup member, a bottom wall of the cup member is superimposed to an end surface of the main rubber elastic body in the axial direction without being bonded, and a circumferential wall of the cup member expands toward an opening side, and, at least in an opening portion, is arranged as a deformation regulation part which has a gap in a state of being separated with respect to the main rubber elastic body toward an outer circumference to be externally inserted.
Claims6
A cylindrical mount, comprising:
- an inner member;
- an outer cylindrical member;
- and
- a main rubber elastic body, in a cylindrical shape, and connecting the inner member and the outer cylindrical member,
- wherein the inner member comprises a cup member open toward the main rubber elastic body,
- an end of the main rubber elastic body in an axial direction is inserted and installed to the cup member, a bottom wall of the cup member is superimposed to an end surface of the main rubber elastic body in the axial direction without being bonded, and
- a circumferential wall of the cup member expands toward an opening side, and the circumferential wall, at least in an opening portion, is arranged as a deformation regulation part which has a gap in a state of being separated with respect to the main rubber elastic body toward an outer circumference to be externally inserted,
- wherein the circumferential wall of the cup member is arranged in a stepped cylindrical shape having a step difference in middle,
- an opening side of the circumferential wall with respect to the step difference is arranged as the deformation regulation part, and
- a bottom side of the circumferential wall with respect to the step difference is arranged as a proximal part closer to an outer circumferential surface of the main rubber elastic body than the deformation regulation part,
- wherein the main rubber elastic body is formed with a groove open on an end surface in the axial direction to which the bottom wall of the cup member is superimposed, and an end of the groove is open on the outer circumferential surface of the main rubber elastic body,
- wherein a bottom side end of the circumferential wall is arranged as a mounting part superimposed to the outer circumferential surface of the main rubber elastic body, and
- a groove depth dimension of the end of the groove open on the outer circumferential surface of the main rubber elastic body is greater than a height dimension of the mounting part in the axial direction.
