閉式排気ダンパ。 A cylindrical body provided in the middle of the exhaust passage, a damper plate rotatably provided inside the body to open and close the exhaust passage, and a damper plate provided so as to be interlocked with the damper plate to keep the damper plate open at all times. The damper plate is made of a shape memory alloy and receives the heat of the exhaust gas passing through the main body directly or indirectly, and opens the damper plate by the shape restoring force when a predetermined high temperature range is reached. A heat-sensitive opening/closing type exhaust damper comprising: a shape memory spring that generates a sufficient output; and a driving force transmitting member that transmits the shape restoring force of the shape memory spring to the damper plate to open and close the damper plate.
