Abstract
A ventilation device has a duct main body, a valve body, and pairs of widened portions. The duct main body has an opening. The duct main body has an upper edge defining a part of the opening. A plurality of insertion slots are formed in and along the upper edge. The valve body has a plurality of substantially triangular engaging pieces provided at an upper end of the valve body. Each engaging piece is inserted in one of the insertion slots, such that the valve body is hung by the duct body to be capable of opening and closing the opening. Each pair of the widened portions is provided at side sections of one of the insertion slots. When the engaging pieces are being inserted in the insertion slots, each pair of the widened portions permit the corresponding engaging piece to be deformed.
