<p>The provided breather pipe structure for a liquid reductant storage tank can take in and expel air in accordance with changes in the amount of liquid in said liquid reductant storage tank. Also, when the liquid reductant is being injected into the tank, the provided breather pipe structure can regulate the liquid level at which the tank is full. In the provided structure, a breather pipe (20) that takes in and expels air is attached to the top of a liquid reductant storage tank (10) that stores a liquid reductant (5). The position of the bottom end (20c) of the breather pipe (20), which extends downwards from the top of the liquid reductant storage tank (10), is the level at which the tank is full.</p> |
