<P>PROBLEM TO BE SOLVED: To provide a urea water tank inhibiting enlargement of a tank and preventing a pressure control valve from being immersed with urea water even if a vehicle is inclined. <P>SOLUTION: The urea water tank for storing the urea water, is mounted on the vehicle, and includes the pressure control valve controlling pressure of an inside through a filter absorbing ammonia. In the urea tank, a projection part including a top part at a position higher than top parts of other sections at an upper part of the urea water tank, the top part of the projection part is positioned higher than a liquid surface of urea water stored inside when the vehicle is inclined in an inclination range of the vehicle, and the pressure control valve controlling pressure of the inside through the filter absorbing ammonia is disposed at the top part of the projection part. <P>COPYRIGHT: (C)2010,JPO&INPIT |
