PROBLEM TO BE SOLVED: To use a cabin in common between backhoes which differ in the height of a bonnet from a steering floor by interposing a spacer member in a space between the bonnet upper surface of a swivel base and the placed surface of a cabin. SOLUTION: In an A-machine A1, to the bonnet height ha from a steering floor 10, the height difference between placed surfaces 23, 24 of a cabin 17 is also set to ha, so that the cabin 17 can be placed on the steering floor 10 and a bonnet 16A as it is. In a B-machine 1B, since the bonnet height hb is set lower than the height difference ha between front and rear placed surfaces 23, 24 of the cabin 17, a space is formed with a bonnet 16B when the cabin 17 is placed on the steering floor 10. Since the cabin 17 has a spacer member 29 so as to fill the space, the cabin 17 can be mounted on the B-machine 1B without any gap. Accordingly, providing the spacer member 29 allows the use of the common cabin 17.
