LIQUID DISCHARGE STRUCTURE

An objective of the present invention is to reduce a space for installation of a casing while discharging liquid collected within the casing and suppressing liquid being introduced into a discharge opening from the outside. A liquid discharge structure 10 includes a plate-shaped bottom wall 11 with a discharge opening 111 for liquid, the liquid being collected inside a casing 1 which is configured to be installed in a vehicle, a blocking wall 12 disposed outside the bottom wall 11 so that the blocking wall 12 is overlapped with the discharge opening 111 in a plan view on the bottom wall 11 and opposed to the bottom wall 11 with a gap d11 between the blocking wall 12 and the bottom wall 11, and a pair of vertical walls extending towards the bottom wall 11 from the blocking wall 12 in a front-rear direction D11 of the vehicle, the pair of vertical walls 13 being opposed to each other in a width direction D12 of the vehicle, wherein the pair of vertical walls is configured to define a discharge path together with the bottom wall 11 and the blocking wall 12, the discharge path 14 being opened towards both of a front and rear side of the vehicle and configured to discharge the liquid in the front-rear direction D11, wherein the liquid has passed through the discharge opening 111.
