An improved dryer exhaust vent comprising an open rectangular body forming an air passage between opposite ends, a pair of cooperating housing caps having an inlet opening into said air passage and an exit openings therefrom, said housing caps defining entrance and exit duct connection means, three pair of spaced notch means having entranceways located along opposite sides of the body edge bounding said inlet opening, and three vanes each having end pivots laterally extending from an upper edge and collectively sized to serve as a closure for said inlet opening, said vanes being mounted by their end pivots in said pairs of notch means and being mounted therein such that said top and middle vanes have their lower edges in slightly overlapped relation, said vanes being movable from said overlapped relation through a pivotal traverse into said air passage towards said exit opening, said inlet opening housing caps being removable and being mounted against said body edge bounding said inlet opening whereby said entranceways of said notch means are closed to retain said vanes within said notches, whereby discharging air is exhausted between the vanes while said vanes remain protected against weather elements within the confines of said air passage.
