Abstract
PURPOSE:To restrain pitching generated in a machine body by providing a trunk roller movable longitudinally of the machine body except for ground contacting rollers located on both longitudinal ends of machine body among the ground contacting rollers. CONSTITUTION:A support bracket 12 is welded to the lateral outside surface of a slide member 11 slidably fitted on a truck frame 3 to support a movable trunk roller 5C under the idling condition. A double-acting type hydraulic cylinder 15 is provided between a mounting member 13 attached to the upper surface of slide member 11 and a mounting member 14 attached to the front side support member 2. A change-over valve 17 for changing over the destination of supplying pressurized oil from a hydraulic pump 16 is changed over by an operating lever 18, so that the hydraulic cylinder 15 is operatively expanded and contracted to displace the movable trunk roller 5C longitudinally of a machine body.
