The right and left front struts of the cabin frame are formed in outwardly protruding circular-arc shapes when viewed from the front and outwardly protruding circular-arc shapes when viewed from the sides. The upper front beam of the cabin frame located in front of the roof is formed in an upwardly protruding circular-arc shape when viewed from the front. The right an left side edges of the front panel are formed along the right and left front struts in outwardly protruding circular-arc shapes when viewed from the front and outwardly protruding circular-arc shapes when viewed from the sides. The upper edge of the front panel are formed along the upper front beam in an upwardly protruding circular-arc shape when viewed from the front. The front panel is formed in a nearly spherical shape that gradually protrudes forward from the right and left side edges and the upper edge toward a central area. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
