構造。 In a construction machine in which a door is installed at the entrance of a cabin so that it can slide back and forth and is pulled inward at the end point on the closing side, a slide frame is installed on the wall plate behind the entrance of the cabin to move back and forth with a constant stroke. On the other hand, a connecting arm is provided at the rear end of the door so as to be rotatable around a vertical axis, and this connecting arm is connected to the slide frame so as to be slidable back and forth with a constant stroke. A cabin door opening/closing structure for a construction machine, which is characterized by:
