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.
