Stacked structure, and heat-exchange-type ventilation device and air purification device using same

A stacked structure comprising:

• a plurality of rib structures;
• and
• a plurality of partition members,
• wherein first air ducts and second air ducts intersecting with the first air ducts in a plan view are alternately provided one by one by alternately stacking each of the plurality of rib structures and each of the plurality of partition members in an up-down direction,
• the each of the plurality of rib structures includes
• a pair of first sides facing each other,
• an end opening provided at an end of the each of the plurality of rib structures along each of the pair of first sides,
• a pair of second sides facing each other, the second sides being different from the first sides, and
• an upper projection and a lower projection provided at the end of the each of the plurality of rib structures along each of the pair of second sides,
• the plurality of rib structures include a central rib structure, an upper rib structure adjacent to the central rib structure on an upper side of the central rib structure, and a lower rib structure adjacent to the central rib structure on a lower side of the central rib structure, and
• at the end opening of the central rib structure, the lower projection of the upper rib structure is fitted via a partition member positioned on an upper side adjacent to the central rib structure among the plurality of partition members, and the upper projection of the lower rib structure is fitted via a partition member positioned on a lower side adjacent to the central rib structure among the plurality of partition members.
