<p>A valve structure of a damper including a piston (1) defining a first chamber (41) and a second chamber (42) within the damper and having a port (2) for communicating the first chamber (41) and the second chamber (42), and a first leaf valve (10) layered to the end surface of the second chamber (42) side of the piston (1), for closing the downstream of the port (2) against the flowing direction of the working fluid when the working fluid is flowing from the first chamber (41) to the second chamber (42), wherein the valve structure further comprising a flow channel (20) for communicating the first chamber (41) and the upstream of the port (2) in the flowing direction, and a restrictor (16, 51) provided in the flow channel (20), and wherein the restrictor (16) decreases the flow channel area in the flow channel (20) when the pressure of the first chamber (41) is exceeded the downstream pressure from the restrictor (16) inside the flow channel (20) by the prescribed level.</p> |
