摘要 PROBLEM TO BE SOLVED: To mount a working lamp while largely securing a storage space for mounted devices in a right front cover. SOLUTION: Second, third and fourth getting-on/off steps 21, 22, 23 project from the front plate 19 of the right front cover 17, a box 26 is installed on the lower side of the second getting-on/off step 21, and the working lamp 29 is contained in the box 26. The working lamp 29 is disposed outside the right front cover 17 containing the mounted devices such as a control valve group 15 and a hydraulic hose/pipe group 16. Since the storage space for the mounted devices can be largely secured in the right front cover 17 and the control valve group 15 and the hydraulic hose/pipe group 16 can be disposed in the right front cover 17 with allowance, the degree of freedom of the layout of these mounted devices can be increased.
