PROBLEM TO BE SOLVED: To suppress work load in maintenance and further to suppress degradation of ventilation efficiency.SOLUTION: A heat exchange ventilation device includes a casing having an air supply passage and an exhaust passage, a heat exchanger detachably mounted in the casing for exchanging heat between air in the air supply passage and air in the exhaust passage, and movement restricting means disposed on a position opposed to the heat exchanger in the casing for restricting movement of the heat exchanger. The movement restricting means restricts the movement of the heat exchanger by being kept into contact with the heat exchanger, and releases the restriction of the movement of the heat exchanger by not kept into contact with the heat exchanger. |
