To provide a fall protection structure capable of protecting an operator by preventing a cabin from being damaged even if a construction machine falls while securing view for working.
In the construction machine in which the cabin 12 is disposed on the lateral one side of an upper rotating body, support bodies 15 and 16 supporting the construction machine 1 in the falling of the construction machine 1 are installed on the upper rotating body 4. The support bodies 15 and 16 are installed on the upper rotating body 4 at the rear of the cabin in the state of being projected in a generally horizontal direction and a generally vertical direction so that a virtual line connecting ground contact points to each other does not invade into the area DLV of the operator seated in the cabin 12 even if the construction machine 1 falls down with a working attachment 5 fallen at the maximum working radius or the construction machine 1 is turned over upside down.
