摘要:
A suspension device includes a partition wall body which partitions the outside of a hollow pipe into a working chamber and a reservoir first chamber, a first piston which partitions the working chamber into an extension-side first chamber and a contraction-side first chamber, a first flow passage which allows communication between the extension-side first chamber and the reservoir first chamber, an extension-side second chamber which communicates with the extension-side first chamber, a second piston which partitions the interior of the hollow pipe into a contraction-side second chamber and a reservoir second chamber, a first damping flow passage which allows communication between an extension-side chamber and a contraction-side chamber, and a second damping flow passage which allows communication between the contraction-side chamber and a reservoir. A cross-sectional area of the extension-side second chamber is larger than that of the hollow pipe.
