PROBLEM TO BE SOLVED: To prevent or reduce leakage of the sound from the inside to the outside of a hood while effectively discharging the heat inside the hood outward. SOLUTION: In a shield plate of a cabin arranged so as to face an engine, a plurality of ribs extending forward within a region reserving a passage opening an inner space of the hood outward at a gap against a rear edge of the hood are arranged. The plurality of ribs are disposed consecutively from the center of the shield plate to the outer peripheral edge side while lying along the outer periphery of the shield plate. A recess part opened forward is formed by one rib of the plurality of ribs and another rib positioned on the outer periphery side of the rib. COPYRIGHT: (C)2011,JPO&INPIT
