Abstract
A suspension includes: a cylinder; a piston rod including a piston provided at one end-side, and inserted in the cylinder together with the piston; an outer tube part opened at the one end-side, a position of which relative to the piston rod is fixed at the other end-side, and configured to receive therein at least a part of the cylinder; and a tubular rolling diaphragm having one end disposed at the cylinder and the other end fixed to the outer tube part, and configured to roll in conjunction with displacement of the piston rod with respect to the cylinder. The rolling diaphragm becomes convex toward the other end-side of the outer tube part and is accommodated in the outer tube part, upon contraction of the suspension.

A suspension comprising:
- a cylinder;
- a piston rod including a piston provided at one end-side, and inserted in the cylinder together with the piston;
- an outer tube part opened at the one end-side, a position of which relative to the piston rod is fixed at the other end-side, and configured to receive therein at least a part of the cylinder;
- and
- a tubular rolling diaphragm having one end disposed at the cylinder and the other end fixed to the outer tube part, and configured to roll in conjunction with displacement of the piston rod with respect to the cylinder;
- and
- a diaphragm having one end fixed to the cylinder and the other end fixed to the other end-side of the suspension, and configured to form an air chamber around at least the piston rod,
- wherein the rolling diaphragm becomes convex toward the other end-side of the outer tube part and is accommodated in the outer tube part, upon contraction of the suspension, and
- wherein the diaphragm is disposed in the outer tube part.
A suspension comprising:
- a cylinder;
- a piston rod including a piston provided at one end-side, and inserted in the cylinder together with the piston;
- an outer tube part opened at the one end-side, a position of which relative to the piston rod is fixed at the other end-side, and configured to receive therein at least a part of the cylinder;
- and
- a tubular rolling diaphragm having one end disposed at the cylinder and the other end fixed to the outer tube part, and configured to roll in conjunction with displacement of the piston rod with respect to the cylinder,
- wherein the rolling diaphragm becomes convex toward the other end-side of the outer tube part and is accommodated in the outer tube part, upon contraction of the suspension, and
- wherein the one end of the rolling diaphragm is disposed to be displaceable with respect to the cylinder.
