An aqueous urea tank structure is provided for a construction machine, in which a temperature rise of the aqueous urea within the tank can be suppressed and the load applied to the tank due to vibration of a vehicle body can be reduced. The aqueous urea tank structure including an aqueous urea tank which is disposed within a revolving upperstructure of a hydraulic excavator to store aqueous urea that purifies the exhaust gas discharged from an engine, wherein the aqueous urea tank structure further includes a securing member which encloses the periphery of the aqueous urea tank to secure the aqueous urea tank within the revolving upperstructure, and heat insulating materials which are interposed between the securing member and the aqueous urea tank to hold the aqueous urea tank. The securing member contains a box.
An aqueous urea tank structure for a construction machine, the aqueous urea tank structure being provided in the construction machine which has a revolving upperstructure, an engine disposed within the revolving upperstructure, and a hydraulic pump driven by drive force of the engine, the aqueous urea tank structure comprising:
