The present invention relates to a urea solution tank capable of supplying and storing urea solution in a urea solution spraying device provided in an exhaust device of a diesel vehicle applied with a selective catalytic reduction (SCR). The urea solution tank comprises: a tank housing storing urea solution; a sensor module mounted so that a heating pipe, an intake pipe, a level sensor, a quality sensor protrude downward; and an air vent which is installed on the upper surface of the tank housing and which discharges gas in the tank housing to the outside. When the level sensor support which is made of a synthetic resin and a synthetic rubber is inserted into the sensor module so as to absorb impact on a bottom end part of the vertical pole-shaped level sensor, the lower surface of the level sensor support closely meets the bottom surface of the inside of the tank housing each other. The heating pipe has a vertical part fixed and connected to a module head vertically downward and a horizontal part horizontally bent in a lower part of the vertical part. A heating pipe support which is made of a synthetic resin and a synthetic rubber is inserted into the horizontal part so as to absorb impact, and a lower part of the heating pipe support closely meets the bottom surface of the inside of the tank housing. Therefore, the urea solution tank for a diesel vehicle with a sensor support can absorb impact and prevent the sensor module from moving while the level sensor support and the heating pipe support support the lower part of the sensor module. |
