An amplitude sensitive damper apparatus that is provided with an amplitude sensitive valve unit may include a plug coupled to a piston rod to form a spring groove with the piston rod in a predetermined section, a spool member configured and dimensioned to cover the spring groove and slidably coupled to the piston rod to move up and down along the piston rod, wherein the spool member includes a supporting portion that protrudes toward the piston rod from a middle portion of an inner surface of the spool member, upper and lower elastic members that are mounted inside the spring groove to support the supporting portion of the spool member upwards and downwards respectively along the piston rod, and an amplitude sensitive valve that is integrally mounted on an outer surface of the spool member to generate a damping force when the spool member is moving. |
