ABSTRACT:
The present invention provides a spacious operation cabin of a construction machine which has a large opening for a door, and which prevents the door from jutting out of the turning radius of the cabin when the door is opened. The outer side (2a) of the operation cabin (2) opposite to a working equipment boom installed on a turntable (1) is formed into an outwardly curved arc including the door (3), and the door (3) is adapted to be freely slidable with rails and rollers which are appropriately positioned. The position of the door (3) when it is opened is controlled to be within the turning radius (R) of the turntable.
