<p>[Problem] To provide an aqueous urea tank structure for a construction machine, in which the rise of the temperature of the aqueous urea within the aqueous urea tank can be suppressed and the load applied to the aqueous urea tank due to vibration of a vehicle body can be reduced. [Solution] An aqueous urea tank structure for a hydraulic excavator (1), the aqueous urea tank structure being provided in the hydraulic excavator (1) which has a revolving upperstructure (3), an engine disposed within the revolving upperstructure (3), and a hydraulic pump driven by the drive force of the engine, the aqueous urea tank structure including an aqueous urea tank (11) which is disposed within the revolving upperstructure (3) to store aqueous urea (11a) that purifies the exhaust gas discharged from the engine, wherein: the aqueous urea tank structure further includes a securing member which encloses the periphery of the aqueous urea tank (11) to secure the aqueous urea tank (11) within the revolving upperstructure (3), and heat insulating materials (13a, 13b) which are interposed between the securing member and the aqueous urea tank (11) to hold the aqueous urea tank (11); and the securing member contains a box (12).</p> |
