Patent ID: 7618593

Claim:
A reducing agent container, comprising: a body; a concentration meter, configured to detect a concentration of a liquid reducing agent based on a heat transmission characteristic between two spaced points, including a base portion being attached on an upper surface of the body; a heat exchanger configured to allow a heating medium using an engine as a heat source thereof to circulate therein and arranged to surround a detecting section of the concentration meter which is suspended from the base portion of the concentration meter via a supporting column thereof, to thereby perform the heat exchange with the liquid reducing agent, the heat exchanger being attached on the upper surface of the body; an encasing member of substantially box shape, having six faces and an interior region, which is arranged to surround a lower portion of the heat exchanger and the detecting section of the concentration meter; and a visor arranged to be attached on the supporting column of the concentration meter, at a position located above and spaced apart from the encasing member by a predetermined interval, wherein the concentration meter and the encasing member are separated by a space, and wherein the supporting column penetrates an upper surface of the encasing member and extends into the interior region of the encasing member.
