Abstract
A urea water tank () is arranged in a cab () at which an operator boards, thereby making it possible to arrange urea water under a preferred temperature environment for preventing freeze and crystallization of the urea water. A water supply port (A) is provided to be opened to a left surface portion (C) of a cab box () constituting the cab () for supplying the urea water to the urea water tank () from an outside of the cab (). Therefore, even in a case of resupplying the urea water to the urea water tank (), an operator can easily resupply the urea water through a water supply hose () to the urea water tank () from the outside of the cab () without entering into the cab ().
