An adjustingleg 17 including a screw portion and a bracket supporting the screw portion may be provided at thebase 16. When the screw portion is turned in one direction, such as, for example, rotated clockwise or counterclockwise, the bracket moves away from thebase 16 to adjust (increase) a height of the ventilation apparatus.

front panel 20 contacts therear panel 18. When a length of the left andright side plates front panel 20 in the front and back direction is greater than a length of the left andright side plates rear panel 18 in the front and back direction, a gap between therear panel 18 and thefront panel 20 is not easily seen or noticed in the interior space in which the ventilation apparatus is installed.
