Abstract:
1. A structure of a reducing agent container having a main body thereof and storing therein a liquid reducing agent used in an exhaust gas purification apparatus for reducing and purifying nitrogen oxide in an exhaust gas, the container main body having an upper surface thereof on which there are provided: a base of a water level indicator which detects a remaining amount of liquid reducing agent; a base of a densitometer which detects concentration of the liquid reducing agent; a heat exchanger which surrounds detectors arranged to suspend from the bases of the water level indicator and the densitometer and to circulate heat medium of which a heat source is an engine to carry out heat exchange between the liquid reducing agent and the heat medium; and a suction tube which allows the liquid reducing agent to be sucked from a position located adjacent to a bottom of the container main body and between the water level indicator and the densitometer; wherein a box-shaped member formed in a substantially box shape is disposed so as to surround the water level indicator, the densitometer and the suction tube located at a position adjacent to a lower portion of the heat exchanger.
