Abstract
A damper opening/closing mechanism includes: a damper which swings about a shaft to open and close a flow passage; an actuating lever which swings so as to swing the damper about the shaft; a reciprocating part which moves reciprocatively; and elastic members which are attached to the reciprocating part and positioned on forward-and-backward both sides in a swinging direction of the actuating lever and moreover which elastically bias the actuating lever along with reciprocative motions of the reciprocating part.
