An object of the present invention is to provide lighting lamps of different colors near a fuel supply port of a fuel tank and a water supply port of a urea water tank, and to illuminate when a cap is opened at the time of supply, thereby erroneous supply. The purpose is to prevent. The present invention provides an openable / closable combine in which a water supply port of a urea water tank (16) is disposed near a predetermined location near a fuel supply port of a fuel tank (12) mounted on a machine base. An oil supply lamp (21) and a water supply lamp (22) of different colors are provided near an oil supply port and a water supply port provided with caps (14, 17), respectively. When the caps (14, 17) are opened, the oil supply lamp ( 21) or the water supply lamp (22) is turned on.
