PROBLEM TO BE SOLVED: To improve the workability of detection and maintenance by greatly exposing a heat exchanger, a hydraulic oil tank, a fuel tank, etc., and to enable a plurality of covers to be locked with one key. SOLUTION: An upper structure 3 is provided with an integrated right cover 30 which concurrently covers the three surfaces, that is, the right side surface part, top surface part and front surface part of the equipment such as the heat exchanger 11, the hydraulic oil tank 12, the fuel tank 13 and a battery 17. This enables the respective pieces of equipment to be greatly exposed to the outside only by opening one right cover 30, and facilitates the detection and the maintenance. A fuel filler cover 34 is openably/closably provided in the integrated right cover 30; and work for feeding oil into the fuel tank 13, and an operation of a locking mechanism 33 for the right cover 30 can be performed by opening the fuel filler cover 34. Thus, the work for feeding the oil into the fuel tank 13 can be easily performed, and the right cover 30 can also be locked with a key cylinder 36 for locking the fuel filler cover 34.
