Abstract

PURPOSE:To facilitate getting on and off from the front face of an operating floor as well as to secure a wide space at the time of operations by providing a handle post inclined toward an operating handle section on the central upper section at a front face from the transversal end section of the operating floor in such a way as to be capable of being rotated to the transversely outward side. CONSTITUTION:A handle post 4 is fitted onto the one front section side of an operating floor at its lower end section in such a way as to be rotatably supported around a tilt axis 14 in the longitudinal direction. It can be rotated from the position in close proximity to the operating floor 2 to the position where it is vertically raised, and a mechanism is concurrently provided, which locks each rotating range of it by an appropriate angle. It is so configurated that the handle post 4 is disengaged from a locking mechanism with a lock pedal 15 depressed, and is engaged therewith again with the depressed pedal released. At the time of operations, the position of the handle post 4 is locked at the front face A of an operator's seat 1 by the use of an operating handle 3, and at the time of getting on and off, the post is locked in an attitude B which is raised to the transversely outward side. In addition, when the post is housed in and so on, the handle post 4 is knocked down in a position close to the upper surface of the operating floor.
