Damping valve
A damping valve includes a valve seat member provided with a port, a valve body that opens or closes the port, a tubular spool that abuts on a side of the valve body opposite to the valve seat member, a spool holding member that has an outer circumference where the spool is mounted movably along an axial direction, a ring mounted to the outer circumference of the spool holding member, the ring contacting slidably with an inner circumference of the spool, and a back-pressure chamber partitioned by the spool and the spool holding member, the back-pressure chamber being configured to bias the spool such that the valve body is pressed toward the valve seat member using an internal pressure, wherein the internal pressure of the back-pressure chamber is applied to an inner circumferential side of the ring.
