2. Description of the Related Art In recent years, from the viewpoint of energy saving, a heat exchange type ventilation unit for recovering heat while exchanging exhaust heat during air conditioning during ventilation with air in a supply air stream has become popular.

Conventionally, a heat exchange type ventilation unit of this type has a main body 101 as shown in FIG. 6, and a blower chamber 102 for accommodating a blower for air supply and a blower for exhaust (neither is shown). And a heat exchange chamber 104 accommodating the heat exchanger 103 for heat recovery. On one side of the main body 101, an opening 105 is provided for laterally attaching and detaching the heat exchanger 103. Since the heat exchanger 103 is held against the ridges 106 on both sides, a sliding rail 107 having a U-shaped cross section is fixed in the heat exchange chamber 104 by a rail mounting member 108.

In the above structure, before housing the heat exchanger 103 in the heat exchange chamber 104, first, the slide rail 107 is fixed inside the heat exchange chamber 104 by a rail mounting member 108, and the heat exchanger 103 is fixed. Are inserted and removed along the sliding rail 107 in the lateral direction.
