摘要

A front side of a floor panel (15) is pivotally supported on a floor panel support mechanism (21), permitting to tilt up the floor panel in forward direction of a revolving frame (5). A tilting mechanism (30) is provided between the floor panel (15) and the revolving frame (5). The tilting mechanism (30) is constituted by a guide rail assembly (33) which is pivotally supported on the side of the revolving frame (5), a screw rod (34) which is rotatably supported on the guide rail assembly (33), and a displacement member (35) which is attached to the floor panel (15) and held in threaded engagement with the screw rod (34). The floor panel (15) and a cab (29) are tilted up in forward direction upon rotationally driving the screw rod (34) to translate the displacement member (35) constituting the tilting mechanism (30). Furthermore, the tilting mechanism (30) can stop and fix the floor panel (15) and a cab (29) at an arbitrary tilted position.
