On a lower part of an outer surface of the front plate, a linear hollow lower rib extending in a right-left direction and a pair of right and left vertical ribs that are in communication with the lower rib at lower ends thereof are provided. An exhaust gas flow path of an exhaust gas is defined including an inner space of the lower rib and an inner space of the vertical ribs. The exhaust gas flow path is in communication a flow-path forming section of a box shape that allows the exhaust gas flowing in the exhaust gas flow path to go downward relative to the lower rib. |
